1. Gather all the files that you wish to hide in a folder anywhere in your PC (make it in C:\hidden - RECOMMENDED).

2. Now, add those files in a RAR archive (e.g. secret.rar). This file should also be in the same directory (C:\hidden).

3. Now, look for a simple JPEG picture file (e.g. logo.jpg). Copy/Paste that file also in C:\hidden.

4. Now, open Command Prompt (Go to Run and type ‘cmd‘). Make your working directory C:\hidden.

5. Now type: “COPY /b logo.jpg + secret.rar output.jpg” (without quotes) - Now, logo.jpg is the picture you want to

show, secret.rar is the file to be hidden, and output.jpg is the file which contains both. :D

6. Now, after you have done this, you will see a file output.jpg in C:\hidden. Open it (double-click) and it will show the

picture you wanted to show. Now try opening the same file with WinRAR, it will show the hidden archive .

Copy a full DVD movie on one disk

Posted by DoMiN8ToR on Monday 5 March 2001A BIGPLUTER FAQ

This FAQ will tell you how to copy a full DVD film onto one disk, with excellent video quality and sound. But before I get started you must have these programs in order to do it because without these you cannot do it cheaply, basically you would have to buy a dvd ripper and some very expensive disks.

Programs needed:

Dvd to Mpeg squeezer.
Panasonic Plugins.
Xing encoder and Xing player (Xing player optional as windows player can run them).

You will probably find them at DVDSoft.net

Once you have installed (here's help) all these programs correctly you have to apply the appropriate settings.

1. Before you start the Dvd to Mpeg squeezer you have to initialize the encoder, then when the box appears you have to click on options.

2. Click on the capture settings box.

3. The frame rate must be 23.976fps.

4. Maximum frame number must be set at 300,000.

5. Leave a tick in the stop capturing by title change.

6. Leaving a tick in add bands is optional as this is for the zoom function.

7. No ticks in the other 2 boxes.

8. Resize filter set to BiCubic filter.

9. Interpolation mode set to No Interpolation.

10. Then come out of that menu and go into MPV settings.

11. This is the main part of the rip and you must get these settings exact or it will not fit on one disk.

12. The Data Rate (kbits/sec) Video must be set to 600kbits/sec delete the number what's in and put that one in the Video. The Audio must read 224 and the System must say 824 and the Stream format must be MPEG1.

13. Noise Reduction must be set to: Medium.
Video filter must be set to: Adaptive.
Level must be set to: Strongest.

Color tone optional but I set it to TV.

These are the settings for a full film rip and full match source taken from a Dvd.

This is the amount of film you can put on:
1. 650 meg disk equals to 106 minutes of
2. 700 meg disk equals to 116 minutes of film.

Now if a film is longer than 116 minutes you will have to encode the film at a lower meg rate. To do this you will have to encode the ripped Dvd down to an NTSC rip or even lower down to a PAL rip. This should put any film onto 1 disk then, but this will still be a very good quality. If you encode a film even lower than PAL say a 384k rip you could get up to 4 hours of film on 1 disk but the quality of the film degrades drastically but watch able from 7 feet away.

This FAQ was written by Bigpluter and can be modified only by someone who has got a littlepluter, but if you do let me know ok.

ONLY BIGPLUTER MAKES IT POSSIBLE.

Reaction by fzkuno on Tuesday 6 March 2001seen as how the goal is not to make a vcd compliant Mpeg stream, why not compress the audio further.. 112 kbit/s does the trick for me..
and why not use DivX instead.. mpeg 1 video is not necessarily the best format, because much of the computing power will go into the bicubic filtering necessary to downscale the video to a cif format in OK quality.

video:
640*320 (for widescreen)at 600kbit/s DivX lowmotion with a keyframe every 3 secs.
bilinear filtering.
and
Audio:
112 kbit/s mp3
and you're all set..I choose DivX low motion because of the nature of the films I usually back up, but fastmotion could be applied as well.

sure the quality of mpeg is good, because of the frequency of keyframes, (1/15 I think..) but the problem is the bicubic filtering, and the rescaling to 352*X
it's just not too cool..

theres a version of flaskmpeg out there with DeCss built in.. that means you can rip directly from the DVD instead of having to copy it to the HD.

What is Network Cabling?

2011-05-02T03:12:00.000-07:00

Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size. Understanding the characteristics of different types of cable and how they relate to other aspects of a network is necessary for the development of a successful network.
The following sections discuss the types of cables used in networks and other related topics.

Unshielded Twisted Pair (UTP) Cable

Twisted pair cabling comes in two varieties: shielded and unshielded. Unshielded twisted pair (UTP) is the most popular and is generally the best option for school networks (See fig. 1).

Fig.1. Unshielded twisted pair

The quality of UTP may vary from telephone-grade wire to extremely high-speed cable. The cable has four pairs of wires inside the jacket. Each pair is twisted with a different number of twists per inch to help eliminate interference from adjacent pairs and other electrical devices. The tighter the twisting, the higher the supported transmission rate and the greater the cost per foot. The EIA/TIA (Electronic Industry Association/Telecommunication Industry Association) has established standards of UTP and rated five categories of wire.

Categories of Unshielded Twisted Pair

Type	Use
Category 1	Voice Only (Telephone Wire)
Category 2	Data to 4 Mbps (LocalTalk)
Category 3	Data to 10 Mbps (Ethernet)
Category 4	Data to 20 Mbps (16 Mbps Token Ring)
Category 5	Data to 100 Mbps (Fast Ethernet)

Buy the best cable you can afford; most schools purchase Category 3 or Category 5. If you are designing a 10 Mbps Ethernet network and are considering the cost savings of buying Category 3 wire instead of Category 5, remember that the Category 5 cable will provide more "room to grow" as transmission technologies increase. Both Category 3 and Category 5 UTP have a maximum segment length of 100 meters. In Florida, Category 5 cable is required for retrofit grants. 10BaseT refers to the specifications for unshielded twisted pair cable (Category 3, 4, or 5) carrying Ethernet signals. Category 6 is relatively new and is used for gigabit connections.

Unshielded Twisted Pair Connector

The standard connector for unshielded twisted pair cabling is an RJ-45 connector. This is a plastic connector that looks like a large telephone-style connector (See fig. 2). A slot allows the RJ-45 to be inserted only one way. RJ stands for Registered Jack, implying that the connector follows a standard borrowed from the telephone industry. This standard designates which wire goes with each pin inside the connector.

Fig. 2. RJ-45 connector

Shielded Twisted Pair (STP) Cable

A disadvantage of UTP is that it may be susceptible to radio and electrical frequency interference. Shielded twisted pair (STP) is suitable for environments with electrical interference; however, the extra shielding can make the cables quite bulky. Shielded twisted pair is often used on networks using Token Ring topology.

Coaxial Cable

Coaxial cabling has a single copper conductor at its center. A plastic layer provides insulation between the center conductor and a braided metal shield (See fig. 3). The metal shield helps to block any outside interference from fluorescent lights, motors, and other computers.

Fig. 3. Coaxial cable

Although coaxial cabling is difficult to install, it is highly resistant to signal interference. In addition, it can support greater cable lengths between network devices than twisted pair cable. The two types of coaxial cabling are thick coaxial and thin coaxial.
Thin coaxial cable is also referred to as thinnet. 10Base2 refers to the specifications for thin coaxial cable carrying Ethernet signals. The 2 refers to the approximate maximum segment length being 200 meters. In actual fact the maximum segment length is 185 meters. Thin coaxial cable is popular in school networks, especially linear bus networks.
Thick coaxial cable is also referred to as thicknet. 10Base5 refers to the specifications for thick coaxial cable carrying Ethernet signals. The 5 refers to the maximum segment length being 500 meters. Thick coaxial cable has an extra protective plastic cover that helps keep moisture away from the center conductor. This makes thick coaxial a great choice when running longer lengths in a linear bus network. One disadvantage of thick coaxial is that it does not bend easily and is difficult to install.

Coaxial Cable Connectors

The most common type of connector used with coaxial cables is the Bayone-Neill-Concelman (BNC) connector (See fig. 4). Different types of adapters are available for BNC connectors, including a T-connector, barrel connector, and terminator. Connectors on the cable are the weakest points in any network. To help avoid problems with your network, always use the BNC connectors that crimp, rather than screw, onto the cable.

Fig. 4. BNC connector

Fiber Optic Cable

Fiber optic cabling consists of a center glass core surrounded by several layers of protective materials (See fig. 5). It transmits light rather than electronic signals eliminating the problem of electrical interference. This makes it ideal for certain environments that contain a large amount of electrical interference. It has also made it the standard for connecting networks between buildings, due to its immunity to the effects of moisture and lighting.
Fiber optic cable has the ability to transmit signals over much longer distances than coaxial and twisted pair. It also has the capability to carry information at vastly greater speeds. This capacity broadens communication possibilities to include services such as video conferencing and interactive services. The cost of fiber optic cabling is comparable to copper cabling; however, it is more difficult to install and modify. 10BaseF refers to the specifications for fiber optic cable carrying Ethernet signals.

Fig.5. Fiber optic cable

Facts about fiber optic cables:

Outer insulating jacket is made of Teflon or PVC.
Kevlar fiber helps to strengthen the cable and prevent breakage.
A plastic coating is used to cushion the fiber center.
Center (core) is made of glass or plastic fibers.

Fiber Optic Connector

The most common connector used with fiber optic cable is an ST connector. It is barrel shaped, similar to a BNC connector. A newer connector, the SC, is becoming more popular. It has a squared face and is easier to connect in a confined space.

Ethernet Cable Summary

Specification	Cable Type	Maximum length
10BaseT	Unshielded Twisted Pair	100 meters
10Base2	Thin Coaxial	185 meters
10Base5	Thick Coaxial	500 meters
10BaseF	Fiber Optic	2000 meters
100BaseT	Unshielded Twisted Pair	100 meters
100BaseTX	Unshielded Twisted Pair	220 meters

Wireless LANs

Not all networks are connected with cabling; some networks are wireless. Wireless LANs use high frequency radio signals, infrared light beams, or lasers to communicate between the workstations and the file server or hubs. Each workstation and file server on a wireless network has some sort of transceiver/antenna to send and receive the data. Information is relayed between transceivers as if they were physically connected. For longer distance, wireless communications can also take place through cellular telephone technology, microwave transmission, or by satellite.
Wireless networks are great for allowing laptop computers or remote computers to connect to the LAN. Wireless networks are also beneficial in older buildings where it may be difficult or impossible to install cables.
The two most common types of infrared communications used in schools are line-of-sight and scattered broadcast. Line-of-sight communication means that there must be an unblocked direct line between the workstation and the transceiver. If a person walks within the line-of-sight while there is a transmission, the information would need to be sent again. This kind of obstruction can slow down the wireless network.
Scattered infrared communication is a broadcast of infrared transmissions sent out in multiple directions that bounces off walls and ceilings until it eventually hits the receiver. Networking communications with laser are virtually the same as line-of-sight infrared networks.
Wireless LANs have several disadvantages. They provide poor security, and are susceptible to interference from lights and electronic devices. They are also slower than LANs using cabling.

Installing Cable - Some Guidelines

When running cable, it is best to follow a few simple rules:

Always use more cable than you need. Leave plenty of slack.
Test every part of a network as you install it. Even if it is brand new, it may have problems that will be difficult to isolate later.
Stay at least 3 feet away from fluorescent light boxes and other sources of electrical interference.
If it is necessary to run cable across the floor, cover the cable with cable protectors.
Label both ends of each cable.
Use cable ties (not tape) to keep cables in the same location together.

What is a Network Operating System?

2011-05-02T03:04:00.000-07:00

Unlike operating systems, such as DOS and Windows, that are designed for single users to control one computer, network operating systems (NOS) coordinate the activities of multiple computers across a network. The network operating system acts as a director to keep the network running smoothly.
The two major types of network operating systems are:

Peer-to-Peer

Peer-to-peer network operating systems allow users to share resources and files located on their computers and to access shared resources found on other computers. However, they do not have a file server or a centralized management source (See fig. 1). In a peer-to-peer network, all computers are considered equal; they all have the same abilities to use the resources available on the network. Peer-to-peer networks are designed primarily for small to medium local area networks. AppleShare and Windows for Workgroups are examples of programs that can function as peer-to-peer network operating systems.

Fig. 1. Peer-to-peer network

Advantages of a peer-to-peer network:

Less initial expense - No need for a dedicated server.
Setup - An operating system (such as Windows XP) already in place may only need to be reconfigured for peer-to-peer operations.

Disadvantages of a peer-to-peer network:

Decentralized - No central repository for files and applications.
Security - Does not provide the security available on a client/server network.

Client/Server

Client/server network operating systems allow the network to centralize functions and applications in one or more dedicated file servers (See fig. 2). The file servers become the heart of the system, providing access to resources and providing security. Individual workstations (clients) have access to the resources available on the file servers. The network operating system provides the mechanism to integrate all the components of the network and allow multiple users to simultaneously share the same resources irrespective of physical location. Novell Netware and Windows 2000 Server are examples of client/server network operating systems.

Fig. 2. Client/server network

Advantages of a client/server network:

Centralized - Resources and data security are controlled through the server.
Scalability - Any or all elements can be replaced individually as needs increase.
Flexibility - New technology can be easily integrated into system.
Interoperability - All components (client/network/server) work together.
Accessibility - Server can be accessed remotely and across multiple platforms.

Disadvantages of a client/server network:

Expense - Requires initial investment in dedicated server.
Maintenance - Large networks will require a staff to ensure efficient operation.
Dependence - When server goes down, operations will cease across the network.

Examples of network operating systems

The following list includes some of the more popular peer-to-peer and client/server network operating systems.

What is a Protocol?

2011-05-02T03:00:00.000-07:00

A protocol is a set of rules that governs the communications between computers on a network. These rules include guidelines that regulate the following characteristics of a network: access method, allowed physical topologies, types of cabling, and speed of data transfer.
See the Topology and Cabling sections of this tutorial for more information.
The most common protocols are:

Ethernet

The Ethernet protocol is by far the most widely used. Ethernet uses an access method called CSMA/CD (Carrier Sense Multiple Access/Collision Detection). This is a system where each computer listens to the cable before sending anything through the network. If the network is clear, the computer will transmit. If some other node is already transmitting on the cable, the computer will wait and try again when the line is clear. Sometimes, two computers attempt to transmit at the same instant. When this happens a collision occurs. Each computer then backs off and waits a random amount of time before attempting to retransmit. With this access method, it is normal to have collisions. However, the delay caused by collisions and retransmitting is very small and does not normally effect the speed of transmission on the network.
The Ethernet protocol allows for linear bus, star, or tree topologies. Data can be transmitted over wireless access points, twisted pair, coaxial, or fiber optic cable at a speed of 10 Mbps up to 1000 Mbps.

Fast Ethernet

To allow for an increased speed of transmission, the Ethernet protocol has developed a new standard that supports 100 Mbps. This is commonly called Fast Ethernet. Fast Ethernet requires the use of different, more expensive network concentrators/hubs and network interface cards. In addition, category 5 twisted pair or fiber optic cable is necessary. Fast Ethernet is becoming common in schools that have been recently wired.

Gigabit Ethernet

The most recent development in the Ethernet standard is a protocol that has a transmission speed of 1 Gbps. Gigabit Ethernet is primarily used for backbones on a network at this time. In the future, it will probably be used for workstation and server connections also. It can be used with both fiber optic cabling and copper. The 1000BaseTX, the copper cable used for Gigabit Ethernet, is expected to become the formal standard in 1999.

LocalTalk

LocalTalk is a network protocol that was developed by Apple Computer, Inc. for Macintosh computers. The method used by LocalTalk is called CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance). It is similar to CSMA/CD except that a computer signals its intent to transmit before it actually does so. LocalTalk adapters and special twisted pair cable can be used to connect a series of computers through the serial port. The Macintosh operating system allows the establishment of a peer-to-peer network without the need for additional software. With the addition of the server version of AppleShare software, a client/server network can be established.
The LocalTalk protocol allows for linear bus, star, or tree topologies using twisted pair cable. A primary disadvantage of LocalTalk is speed. Its speed of transmission is only 230 Kbps.

Token Ring

The Token Ring protocol was developed by IBM in the mid-1980s. The access method used involves token-passing. In Token Ring, the computers are connected so that the signal travels around the network from one computer to another in a logical ring. A single electronic token moves around the ring from one computer to the next. If a computer does not have information to transmit, it simply passes the token on to the next workstation. If a computer wishes to transmit and receives an empty token, it attaches data to the token. The token then proceeds around the ring until it comes to the computer for which the data is meant. At this point, the data is captured by the receiving computer. The Token Ring protocol requires a star-wired ring using twisted pair or fiber optic cable. It can operate at transmission speeds of 4 Mbps or 16 Mbps. Due to the increasing popularity of Ethernet, the use of Token Ring in school environments has decreased.

FDDI

Fiber Distributed Data Interface (FDDI) is a network protocol that is used primarily to interconnect two or more local area networks, often over large distances. The access method used by FDDI involves token-passing. FDDI uses a dual ring physical topology. Transmission normally occurs on one of the rings; however, if a break occurs, the system keeps information moving by automatically using portions of the second ring to create a new complete ring. A major advantage of FDDI is speed. It operates over fiber optic cable at 100 Mbps.

ATM

Asynchronous Transfer Mode (ATM) is a network protocol that transmits data at a speed of 155 Mbps and higher. ATM works by transmitting all data in small packets of a fixed size; whereas, other protocols transfer variable length packets. ATM supports a variety of media such as video, CD-quality audio, and imaging. ATM employs a star topology, which can work with fiber optic as well as twisted pair cable.
ATM is most often used to interconnect two or more local area networks. It is also frequently used by Internet Service Providers to utilize high-speed access to the Internet for their clients. As ATM technology becomes more cost-effective, it will provide another solution for constructing faster local area networks.

Protocol Summary

Protocol	Cable	Speed	Topology
Ethernet	Twisted Pair, Coaxial, Fiber	10 Mbps	Linear Bus, Star, Tree
Fast Ethernet	Twisted Pair, Fiber	100 Mbps	Star
LocalTalk	Twisted Pair	.23 Mbps	Linear Bus or Star
Token Ring	Twisted Pair	4 Mbps - 16 Mbps	Star-Wired Ring
FDDI	Fiber	100 Mbps	Dual ring
ATM	Twisted Pair, Fiber	155-2488 Mbps	Linear Bus, Star, Tree

Networking hardware includes all computers, peripherals, interface cards and other equipment needed to perform data-processing and communications within the network. CLICK on the terms below to learn more about those pieces of networking hardware.

This section provides information on the following components:

File Servers

A file server stands at the heart of most networks. It is a very fast computer with a large amount of RAM and storage space, along with a fast network interface card. The network operating system software resides on this computer, along with any software applications and data files that need to be shared.
The file server controls the communication of information between the nodes on a network. For example, it may be asked to send a word processor program to one workstation, receive a database file from another workstation, and store an e-mail message during the same time period. This requires a computer that can store a lot of information and share it very quickly. File servers should have at least the following characteristics:

800 megahertz or faster microprocessor (Pentium 3 or 4, G4 or G5)
A fast hard drive with at least 120 gigabytes of storage
A RAID (Redundant Array of Inexpensive Disks) to preserve data after a disk casualty
A tape back-up unit (i.e. DAT, JAZ, Zip, or CD-RW drive)
Numerous expansion slots
Fast network interface card
At least of 512 MB of RAM

Workstations

All of the user computers connected to a network are called workstations. A typical workstation is a computer that is configured with a network interface card, networking software, and the appropriate cables. Workstations do not necessarily need floppy disk drives because files can be saved on the file server. Almost any computer can serve as a network workstation.

Network Interface Cards

The network interface card (NIC) provides the physical connection between the network and the computer workstation. Most NICs are internal, with the card fitting into an expansion slot inside the computer. Some computers, such as Mac Classics, use external boxes which are attached to a serial port or a SCSI port. Laptop computers can now be purchased with a network interface card built-in or with network cards that slip into a PCMCIA slot.
Network interface cards are a major factor in determining the speed and performance of a network. It is a good idea to use the fastest network card available for the type of workstation you are using.
The three most common network interface connections are Ethernet cards, LocalTalk connectors, and Token Ring cards. According to a International Data Corporation study, Ethernet is the most popular, followed by Token Ring and LocalTalk (Sant'Angelo, R. (1995). NetWare Unleashed, Indianapolis, IN: Sams Publishing).

Ethernet Cards

Ethernet cards are usually purchased separately from a computer, although many computers (such as the Macintosh) now include an option for a pre-installed Ethernet card. Ethernet cards contain connections for either coaxial or twisted pair cables (or both) (See fig. 1). If it is designed for coaxial cable, the connection will be BNC. If it is designed for twisted pair, it will have a RJ-45 connection. Some Ethernet cards also contain an AUI connector. This can be used to attach coaxial, twisted pair, or fiber optics cable to an Ethernet card. When this method is used there is always an external transceiver attached to the workstation. (See the Cabling section for more information on connectors.)

RJ-45, AUI, and BNC connectors

LocalTalk Connectors

LocalTalk is Apple's built-in solution for networking Macintosh computers. It utilizes a special adapter box and a cable that plugs into the printer port of a Macintosh (See fig. 2). A major disadvantage of LocalTalk is that it is slow in comparison to Ethernet. Most Ethernet connections operate at 10 Mbps (Megabits per second). In contrast, LocalTalk operates at only 230 Kbps (or .23 Mbps).

Ethernet Cards vs. LocalTalk Connections
Ethernet	LocalTalk
Fast data transfer (10 to 100 Mbps)	Slow data transfer (.23 Mbps)
Expensive - purchased separately	Built into Macintosh computers
Requires computer slot	No computer slot necessary
Available for most computers	Works only on Macintosh computers

Requires computer slot	No computer slot necessary
Available for most computers	Works only on Macintosh computers

Token Ring Cards

Token Ring network cards look similar to Ethernet cards. One visible difference is the type of connector on the back end of the card. Token Ring cards generally have a nine pin DIN type connector to attach the card to the network cable.

Switch

A concentrator is a device that provides a central connection point for cables from workstations, servers, and peripherals. In a star topology, twisted-pair wire is run from each workstation to a central switch/hub. Most switches are active, that is they electrically amplify the signal as it moves from one device to another. Switches no longer broadcast network packets as hubs did in the past, they memorize addressing of computers and send the information to the correct location directly. Switches are:

Usually configured with 8, 12, or 24 RJ-45 ports
Often used in a star or star-wired ring topology
Sold with specialized software for port management
Also called hubs
Usually installed in a standardized metal rack that also may store netmodems, bridges, or routers

Repeaters

Since a signal loses strength as it passes along a cable, it is often necessary to boost the signal with a device called a repeater. The repeater electrically amplifies the signal it receives and rebroadcasts it. Repeaters can be separate devices or they can be incorporated into a concentrator. They are used when the total length of your network cable exceeds the standards set for the type of cable being used.
A good example of the use of repeaters would be in a local area network using a star topology with unshielded twisted-pair cabling. The length limit for unshielded twisted-pair cable is 100 meters. The most common configuration is for each workstation to be connected by twisted-pair cable to a multi-port active concentrator. The concentrator amplifies all the signals that pass through it allowing for the total length of cable on the network to exceed the 100 meter limit.

Bridges

A bridge is a device that allows you to segment a large network into two smaller, more efficient networks. If you are adding to an older wiring scheme and want the new network to be up-to-date, a bridge can connect the two.
A bridge monitors the information traffic on both sides of the network so that it can pass packets of information to the correct location. Most bridges can "listen" to the network and automatically figure out the address of each computer on both sides of the bridge. The bridge can inspect each message and, if necessary, broadcast it on the other side of the network.
The bridge manages the traffic to maintain optimum performance on both sides of the network. You might say that the bridge is like a traffic cop at a busy intersection during rush hour. It keeps information flowing on both sides of the network, but it does not allow unnecessary traffic through. Bridges can be used to connect different types of cabling, or physical topologies. They must, however, be used between networks with the same protocol.

Routers

A router translates information from one network to another; it is similar to a superintelligent bridge. Routers select the best path to route a message, based on the destination address and origin. The router can direct traffic to prevent head-on collisions, and is smart enough to know when to direct traffic along back roads and shortcuts.
While bridges know the addresses of all computers on each side of the network, routers know the addresses of computers, bridges, and other routers on the network. Routers can even "listen" to the entire network to determine which sections are busiest -- they can then redirect data around those sections until they clear up.
If you have a school LAN that you want to connect to the Internet, you will need to purchase a router. In this case, the router serves as the translator between the information on your LAN and the Internet. It also determines the best route to send the data over the Internet. Routers can:

Direct signal traffic efficiently
Route messages between any two protocols
Route messages between linear bus, star, and star-wired ring topologies
Route messages across fiber optic, coaxial, and twisted-pair cabling

How to UTP Cabling

2011-04-18T01:43:00.000-07:00

UTP, stands for “unshielded twisted pair”. Called unshielded because less resistant to electromagnetic interference. And called twisted pair as it includes couples who are prepared spiral cable berlilitan alias each other. There are 5 categories of UTP cable. From category 1 to category 5. For the famous computer network is a category 3 and category 5.
Category 3 can be used for data transmission up to 10 mbps, while category 5 to 100 mbps. If only create such a network in your office or campus computer or internet cafe, yes the most efficient use of the category 3. That was more than enough.

As far as the writer there are many brands on the market, it’s just that stubborn and relatively cheap famous brand is Belden – Made in USA. If you want a cheaper and use a lot, then just buy one box, approximately 150 meters in length. Do not forget to buy the connectors. Shaped like a telephone socket connector only bigger.

Another very important, you must have a special pliers for installing the connector to the UTP cable, fancy term is “the crimp tool.” This tool is useful to ‘turn off’ or ‘planting’ connector to the UTP cable. So once already in the ‘tang’, then it can not be removed again connectors. And if you want a more OK, I’ll not bear the same buy a LAN tester. You can buy a brand from Taiwan just so much cheaper. Shaped like a box and there are LED lights his eight pairs and can-blink-resistant.

OK now you ready tools, the authors start. In general, the UTP cabling are of two types, namely straight and cross type. Type is called straight because each cable corresponding numbers were 1-1 8, directly. While called a cross because there are crosses on the composition of the cord. Confused?

OK! For the straight type is used to connect the cable from the client to the hub. While for the type of cross is to the client directly connected to the client (cpu to cpu) or also from hub to hub.

We first discuss the types of straight
This type is most easily made. Why? Because the direct correspondence 1-1. Standard sequence like this: 2 orange – green 1 – 2 blue – green 1 – 2 brown. 2 orange here meaning the same pair of young orange dark orange and so on. But do not come standard staining was also really no problem. The important sequence of the cord. For example the first end of the first order of pins young orange, the other end of the first order of the pins must also be young orange, so between the end connect to each other. Actually, not all pins are used.

The important thing is the pin numbers 1,2,3 and 6. So for example which are connected only pins 1,2,3 and 6 while the other pins are not installed, no problem. For more details, please see the picture below is the author of a book of photographs.

Who left the order for the type of correspondence straight, the right of the cross

Time will install it, then cut the tip of the cord, then stacking the cord then flattened with a knife cutting at the crimp tool available. Andak not have to bother to let go at the end of the cable insulation, because when you insert the cable into the connector then pressed (pressed) using a crimp tool, when it was actually there at the connector pins that penetrate down to the wire. Consider, for emphasis (pressing) a hard, hard sometimes because if you do not pin it does not penetrate into the cable insulation. If you have then you test using the LAN tester. Insert the tip ends of the wires to the device, then turn it on, if the LED lights on the LAN tester that lights up everything, from number 1 to 8 means that you have been successful. If there’s one that does not work means the possibility of the pin numbers are no problem. The easiest way is that you press (press), again using the pliers. Possibility of the pin has not been transparent. If you press but still does not connect, then try to check the correspondence between pins 1-1 or have not already. If it was true and still fail, then indeed you are not lucky. Repeat again until it works.

Change Startbutton text

2011-04-14T03:41:00.000-07:00

Hacking the Start button
This works on XP Pro Build 2600 (The final verison),
and it should work on all other versions as well.

ALWAYS BACKUP EVERYTHING YOU EDIT OR DELETE.
I'M NOT RESPONSIBLE IF YOU MESS YOUR COMPUTER
UP BY DOING THIS HACK. DO IT AT YOUR OWN RISK.

First off, you need to download a program called
Resource Hacker. It's kinda like a hex editor,
it allows you to change bitmaps, text, ect.
in program files.
Windows XP has a feature called Windows File Protection.
This feature stops you from changing important system files,
that could leave your operating system, non-fuctional.
The file that we need to edit, Explorer.exe,
is protected by Windows File Protection. What we need to do,
is make Explorer.exe not part of Windows File Protection.
Once we do that, we will be able to edit
Explorer.exe when we want, and as much as we want.

Click on your start button -> then Run and type in
"%systemroot%system32Restore" without the quotes.
Now you should see the file filelist.xml.
What? You don't see it? We can fix that.
In windows explorer click Tools->Folder Options->
View and scroll down where it says Hide protected
operating system files (recommend) and un-check it.
Also click where it says Show hidden files and folders,
and uncheck Hide extensions for unknown file types. Lastly, hit Ok.
Now, you should see filelist.xml listed. Right click on filelist.xml
and click properties. Uncheck where it says Read Only and then click OK.
Good, now we can edit filelist.xml. Right click filelist.xml again,
and click Open with then on Notepad.
The file should now be opened in notepad.
This is where Windows File Protection looks to see if it needs to
protect a file or not. Where it says:

%windir%system.ini

add this a line above it:

%sytemroot%explorer.exe

Now, click file -> Save. (NOT Save as)

Next click on your start menu-> run and type in
"%systemroot%system32dllcache" without the quotes.
In this DIR, find and delete Explorer.exe.
This is a backup copy of Explorer.exe and windows might
try and replace this copy with your hacked copy if it isn't deleted.
After you delete it, windows will popup a message, just hit cancel then yes.

We should now be able to edit Explorer.exe as we wish. Run Resource Hacker
(The file you downloaded earlier). In ResHacker click File->
Open and open Explorer.exe. Mine is located in C:winntexplorer.exe
yours maybe located in C:windowsexplorer.exe. Once you have it open you should see something like this:

To change the "Start" text on the start button go to:
String Table -> 37 -> 1033. To the right, you should see the words "start".
You can change this to anything you want. I changed mine to LinuXProX.
Next, hit the Compile Script button above.
Now, go to String Table -> 38 -> 1033. Again, to the right you should see "Start".
Change this to the same thing you changed the other one to, mine says LinuXProX. Next,
hit the Compile Script button above. Now, if you just wanted to change the start button text,
you can skip down to "Saving".

Don't you hate the little icon (image) on the start button? Well,
we change it, and it's very easy to do.
In ResHacker, go to Bitmap -> 143 -> 1033.
You should see the window that is on the start button to the right.
To change it, you Action -> Replace bitmap -> Open with new bitmap.
Now you can make your own image, If you want to make your own,
it has to be 25x20 and 16 million colors. Once you found the bitmap you want to use,
just click open then click Replace.

Lastly, to change the Start Menu border, go to Bitmap -> 167 -> 1033.
(This is Windows XP Pro. If you have Home Editon It's Bitmap->166->1033) Click Action ->
Replace bitmap -> and where it says Select bitmap to replace:
scroll down to 167 or 166 if you have XP Home Editon.
Now, click Open file with new bitmap and find the image you want to replace it with,
click open, then on Replace.
It's best to make your own image on this one,
I just edited the default bitmap since I'm not that great with graphics.
Maybe someone will make me a cool one, and send to me. *Hint* *Hint* :)
If you want to edit the default image, or use it as a template,
just right click on the Windows XP Pro/Home image and click copy.
Now, open up your favorite graphics program, I have Jasc Paint Shop Pro,
and hit CTRL-V. That should paste the image from your clipboard to your graphics program.
If you want to make your own, it has to be 21x233 16 million colors. Once your down editing,
just save it as a .bmp somewhere on your drive. I saved mine to C: est.bmp :).

Additional Comments:

-Saving

There are alot of bitmaps in Explorer.exe along with Text Strings, that you can change,
just hack around in it and see what you can find. If you try and save Explorer.exe it wont save.
Why? Because Explorer.exe is currently running on your computer and it can't save it
while the program is running. So how am I suppose to save it? Well, there are a few ways to do that.
One, you could save your hacked version to floppy, boot to dos and copy it.
Two, if you dual boot you could save it from within another operating system.
Or three, the easiest and fastest way, save it without rebooting, and here is how:

Hit CTRL-ALT-DEL and Windows Task Manager should popup.
Click on the processes tab and find Explorer.exe, and click it once.
Now, hit the end process button at the bottom (Make sure you don't have any other programs open).
Your taskbar at the bottom of the screen should disappear.
Hold ALT then click tab while holding ALT, then let off the ALT.
Keep doing this until Resource Hacker comes in to view.
We can now save Explorer.exe because it is not running. Click File-> Save as->
and find Explorer.exe again, mine is located in C:winnt.
It will ask you if you want to overwrite, just click yes.
Now, ALT-TAB back to Windows Task Manager and click on File -> New Task ->
in the black type in Explorer.exe, or type in the full path to explorer like:
C:winntexplorer.exe. If you did everything correctly,
you should see your new image and name on the start button, along with the start menu border.

You will also find that Goodwill Community Foundation will provide people with several free computer technology courses as well. There are tons of options out there for people to learn computer technology and go far in their lives.

What is a FTP Client?

2011-04-08T07:27:00.001-07:00

What is a FTP Client? As a website or blog owner, knowing how to use a FTP client (FTP software) is a useful skill. Instead of relying on your WYSWYG (What you see what you get) software or the interface of your blogging software to upload files, images and other content to your webspace you can use a FTP client and be in full control. What Does FTP Stand For? FTP is the acronym for the File Transfer Protocol, a protocol for transfering files. What is FTP Software Used For? FTP software (or FTP client) is used to copy files from one computer to another over the Internet. Your FTP software connects to another computer connected to the Internet using a file host name, user name and password when we are talking about using it to upload (or download) files and content for your website or blog. FTP Security Regular FTP transfers are not secure. The data sent over the Internet is not encrypted therefore the file, user name, password and commands sent can be read/seen by a packet sniffer (capture) piece of software surfing the net to find such information. For better security use a FTPS connection. Using a FTP Client First of all, you have to download a FTP program. FTP clients can either be free or a paid version. Comparison of FTP Client Software at Wikipedia has a list sorted by free, freeware,freeware and payware, payware and operating system. You will need the FTP information from your web hosting firm. Try and get the secure FTP information. Once you have installed the FTP client on your computer you need to set it up for the site you wish to FTP the files to. Start the FTP client and enter: 1. A profile name. The profile name can be anything you want. Make it something that will make sense to you later if you will be using the FTP software for more than one site. 2. The host name. The host name will be given to you by your web hosting compay. It can be an IP address (123.123.123.123) or your domain name with ftp in front (ftp.mydomain.com). 3. Your FTP user name. Depending on how your web hosting handles FTP, you could have been automatically assigned a FTP user name or you may have to create a FTP account yourself. 4. Your FTP password. For security reasons, this should be different from your web hosting account login password. If your web hosting company has setup the FTP account with the same password as your main login, change it to something else. Use PCTools Secure Password Generator to create a secure password. Make sure you record it somewhere for safekeeping! Also for security reasons, do not save the password to the software. If you do, anyone that gains access to your computer can upload/download or otherwise mess up your site. Don’t worry, you will soon remember the password to enter each time you use the FTP client. 5. Location of files on your computer. To make things easier each time you use the FTP client, enter the path on your computer to the folder that contains your website or blog’s files. 6. Location of the folder on the web server. Like the location of the files on your computer, if you enter the path to the correct location on the web server for your site you won’t have to navigate the path next time you use the FTP client. Using a FTP client to transfer your website or blog files is a skill each site owner should learn. You can also use your FTP client software to backup your site. You have a backup, right?

Definition of 3G:

2011-04-08T06:32:00.000-07:00

3G is the third generation of wireless technologies. It comes with enhancements over previous
wireless technologies, like high-speed transmission, advanced multimedia access and global
roaming. 3G is mostly used with mobile phones and handsets as a means to connect the phone
to the Internet or other IP networks in order to make voice and video calls, to download
and upload data and to surf the net.

3G has the following enhancements over 2.5G and previous networks:

Several times higher data speed;
Enhanced audio and video streaming;
Video-conferencing support;
Web and WAP browsing at higher speeds;
IPTV (TV through the Internet) support.

3G Technical Specifications:

The transfer rate for 3G networks is between 128 and 144 kbps (kilobits per second)
for devices that are moving fast and 384 kbps for slow ones(like for pedestrians).
For fixed wirelessLANs, the speed goes beyond 2 Mbps.

3G is a set of technologies and standards that include W-CDMA,
WLAN and cellular radio, among others.

3G follows a pattern of G's that started in the early 1990's by the ITU.
The pattern is actually a wireless initiative called the IMT-2000
(International Mobile Communications 2000). 3G therefore comes
just after 2G and 2.5G, the second generation technologies.
2G technologies include, among others, the Global System for
Mobile (GSM)
- the famous mobile phone technology we use today.
2.5G brings standards that are midway between 2G and 3G,
including the General Packet Radio Service (GPRS),
Enhanced Data rates for GSM Evolution (EDGE),
Universal Mobile Telecommunications System (UMTS) etc.

What is Required for Using 3G?:

The first thing you require is a device (e.g. a mobile phone)
that is 3G compatible. This is where the name 3G phone comes
from - a phone that has 3G functionality; nothing to do with the
number of cameras or the memory it has. An example is the iPhone 3G.

3G phones commonly have two cameras since the technology
allows the user to have video calls, for which a user-facing
camera is required for capturing him/her.

Unlike with Wi-Fi which you can get for free in hotspots, you
need to be subscribed to a service provider to get 3G network
connectivity. We often call this kind of service a data plan or network plan.

Your device is connected to the 3G network through its SIM card
(in the case of a mobile phone) or its 3G data card
(which can be of different types: USB, PCMCIA etc.),
which are both generally provided/sold by the service provider.
Through that, you get connected to the Internet whenever you are
within a 3G network. Even if you are not in one, you can still use
2G or 2.5G services provided by the service provider.

What Does 3G Cost?:

3G is not very cheap, but it is worthwhile for users that
need connectivity on the move. Some providers offer
it within a somewhat costly package, but most of them have
plans where the user pays for the amount of data transferred
. This is because the technology is packet-based. For example,
there are service plans where there is
a flat rate for the first Gigabyte of data transferred,
and a per minute cost for each additional Megabyte.

3G and Voice:

Wireless technologies are a way for mobile users to make free or
cheap calls worldwide and save a lot of money
due to the latest telephony applications and services.
3G networks have the advantage of being available on the
move, unlike Wi-Fi, which is limited to a few meters
around the emitting router. So, a user with a 3G phone and
a 3G data plan is well-equipped for making free mobile calls.
She will only have to download one of the free
applications and install on
her mobile phone and start making calls. Here are examples of mobile VoIP services.

Using VoIP is a great way of saving money on phone calls. Here's how
