A good network security ensures that your company needs to meet regulatory requirements, due to network security to protect sensitive data and reduce the risk of data theft to fulfill. Network security also avoid your company’s media because of bad credit ratings due to security breaches. Ultimately ensures network security protection for your most important asset – your reputation.

In short, the measures implemented to protect the security of computer network in your office by the integrity, reliability, usability and security of computer networks and data.

Term, Computer Network Security

Network security starts with authenticating the user, usually with a username and password. Since this is only one of the user name, password, ie, sometimes a single-factor authentication is called. With two-factor authentication, “have” is used (eg, ATM card or cell phone), or with your three-factor authentication “is” being used (eg fingerprint).

After confirming firewalls enforce access policies such as what services can be accessed by network users. Although effective to prevent unauthorized access, these components can not check for potentially harmful content such as worms or Trojan horses sent through to the network. Anti-virus software and intrusion prevention system (IPS) to detect and block the action of the pest. An anomaly-based intrusion detection system can also network traffic for the content and the unexpected (ie, suspicious) or other abnormal behavior, and resources, such as denial-of-service attack or an employee access to the file . protect

Network Security Implementation

Required for network security skills:

• LAN / WAN networks and computer networking solutions
• Multi-Service Network

Computer Network Consulting can be provided as one-off projects or as part of ongoing management services, as the need determines. VFZDKVJA88ZW

Ram? Mouse? One is an animal and one is a rodent right? Ram: that is the zodiac sign for Aries. If this is what these words mean to you than you can surely use this quick glossary of computer terminology. It would be a good idea to read through them before purchasing a computer because these are things you should know about first. If you already have a computer then these computer terms can help you know what to do if your new computer equipment is unfamiliar. Also, this computer terminology can help you if you have to call in for technical help.

Cache: Cache is another type of memory kindred to RAM. The computer uses cache to quickly move data between the RAM and the CPU.

CD-ROM Drive: Most new computers now come with a CD-ROM drive as standard equipment. A CD-ROM drive reads data from a disc. These CDs look like a music CD, but hold data instead of music. CD-ROMs also contain games, dictionaries, recipe files, and lots of other things that you can load onto your computer.

CPU: The CPU, or central processing unit, is the brains of the computer. Most new Windows based programs use a Pentium processor or a AMD Athlon XP. New Macs use a different type of CPU called Power PC.

Disk Drive: Virtually all computers come with a disk drive that can read and save information on portable diskettes, also called floppy disks. You can use floppy disks to save information or to load new software onto your computer.

Hard Drive: The hard drive is also called the hard disk. You’ll probably never see it because it is nestled inside your computer. It’s the computer’s electronic filling cabinet, and it stores the computer’s operating system, files, programs and documents.

Keyboard: Just like a typewriter keyboard, this device is the primary way of inputting data into the computer programs.

Megahertz (MHz): This is the clock speed of the microprocessor. The higher the number, the quicker the information is processed. MHz relates to how many millions of instructions can be processed per second.

Memory: This is the circuitry or device that holds information in an electrical or magnetic form. There is read-only memory (ROM), which is information primarily stored on a disk, and random-access memory (RAM), which is chip-based storage inside the computer. Memory is typically measured in megabytes (MBs).

Modem: This mechanism connects a computer to a phone line so information can be sent from one computer to another or the user can access an on-line service or the Internet. In view of the popularity of the Internet, a modem is now considered basic equipment and comes on practically all-new computers. Most modems come with fax capabilities.

Monitor: An output device that allows you to see what you are doing (it is what you are looking into right now to see this). Most computers come with 14 or 15-inch monitors. This size is good for most people’s needs. Larger 17 or 21-inch monitors also are available, but may cost more.

Motherboard: The motherboard is the circuit board that everything in the computer plugs into. The CPU, RAM and cache all plug into the motherboard.

Mouse: The mouse is another input device that makes getting around in your computer easier. It is a handheld object that is good for doing tasks such as moving and pointing to objects on the screen, and can replace the function and control keys of the keyboard. (If you need a lesson on how the mouse works and how to use it click here for a tutorial.)

Printer: A printer is an essential part of the computer if you want a hard copy of your work. There are four types of printers on the market: dot matrix, inkjet, bubble jet and laser. The dot matrix is the most basic. Most inkjets and bubble jets can print color and graphics, and a laser printer offers the best resolution at the highest speed.

RAM: Computers save data in two ways: on the hard drive and in random access memory or internal memory. New computer buyers should look for models with at least 16 MBs of RAM (or more, depending on what types of programs you’ll be running). Make sure that the computer can be upgraded.

Scanner: A scanner is a useful accessory to have if you are working with lots of artwork or photos. This device can copy written documents, pictures or photographs directly into your computer. There are three types of scanners: handheld, hopper-feed and flatbed.

Sound Card: This device allows your computer to reproduce music, sounds and voices. Make sure you have a sound card if you’re planning to play multimedia games.

Video Card: The video card is the part of the computer that sends the images to the monitor.

Well there you have it, a quick course on computer terms. I hope it has helped to guide you in your purchase of a new computer; or to help you with the one you have.

Where do you start? There are so many brands and models of computers available, and it can all be a little overwhelming when you start to look around.

How do you decide what type of computer you need? And perhaps more importantly, how do you decide what the best value is?

1. Buy What You Need, Maybe a Little More

One of the most important things you can do when buying a new computer is make a list of the things that you will be using it for. There are so many different models with different capabilities that you can easily buy more, or less, than you really need if you don’t.

If this is your first computer, this can be a little tougher. Until you’ve used a computer, it’s hard to know exactly what you might want to do with it beyond the obvious, like connecting to the internet.

Regardless, you should think about some of the things you might want to do. Some possibilities include:

• Connect to the internet
• Play games
• Digital photography
• Digital video
• Type documents
• Accounting
• Design websites
• Programming
• Digital scrapbooking
• Geneology

Some of these things need more power than others. For example, connecting to the internet really doesn’t need a lot of power. Even the most basic computer available will probably work just fine.

Digital video and many games need a lot more power. If you don’t get a fast enough computer with enough memory, you’ll be disappointed with the performance.

Knowing what you’re going to be using your computer for will help your salesperson, whether they’re on the phone, the internet or standing in front of you, recommend the best system for your needs.

As a general rule you’re always better off buying more power than you need rather than less, but buying too much can be a waste of money.

2. Warranty Considerations

Computer warranties are one of the most confusing and obscure parts of your purchase. Most manufacturers have cut back on their customer service to the point where poor service has become a given.

The three most common options are onsite, carry-in or manufacturer’s depot service.

Onsite service can be helpful, but think about whether you want to have to be available for a technician to come and diagnose your computer, and possibly have to come back with parts at another time.

Carry in service is a good option, but find out whether the service center is factory authorized for warranty repairs, as well as whether the technicians are all certified.

Shipping your computer to a factory service center can take a long time, sometimes a number of weeks. It also creates risk that your computer will be damaged or even lost in shipping. In some cases, the manufacturer will even replace your computer with another unit and ship it back to you, rather than repairing it. This can result in your losing any information that was on your system and having to reload all your software.

Another aspect of the warranty to find out about is technical support. Find out if the computer manufacturer offers a toll-free phone number and what the quality of service is like.

The better computer salespeople will be honest about this and tell you if a company’s service leaves something to be desired. You can also do some research on the internet, most of the computer magazines like PC Magazine and PC World have annual customer service comparisons that rate the larger computer companies.

Always find out how the warranty is handled before making your decision. Even if it doesn’t influence your choice, knowing what to expect if something does go wrong will save some nasty surprises down the road.

3. Can You Negotiate the Price Down?

A computer is a relatively large investment, anywhere from a few hundred to a few thousand dollars. Many computer buyers expect that there is a significant amount of “wiggle room” on the price.

The reality is that most computer hardware – the physical pieces like the computer, monitor and printer is sold at very low profit margins. Often, computer systems are even sold at or below the dealer cost. When you’re buying a computer, it never hurts to ask for a better deal, but don’t be surprised if you only get a few dollars off, if anything.

What you can do to get the best price is to do some comparison shopping. Most computer stores offer price matching guarantees, so if you find your computer for less at another store, most dealers will match or beat that price, even if it means they lose money.

4. How Do Computer Stores Make Any Money?

You might be wondering how these computer stores make any money if they’re selling computer for so little profit.

Their money is made on add-on items. The highest profit areas in most computer stores are cables and “consumable” products such as printer ink and paper.

Printer ink is a huge money-maker for most computer stores (even more so for the printer manufacturers). Why is this? Once you’ve bought a printer, you’re going to have to replace your ink at some point, and continue to replace it as it runs out.

Most chain computer stores and office supply stores that carry a large selection of ink cartridges make more from ink than they do from the computers themselves.

If you’re buying a new computer, you will likely need to buy some cables. Some items printers, for example don’t often include the cables needed to hook them up.

Many printers also come with “starter” ink cartridges that are only half-full. You might also want to pick up some extra ink cartridges.

This is where you should be able to negotiate a better price. Don’t expect the salesperson to throw them in for nothing, but they should be willing to offer you a better price. After all, if you’re happy with their service, you’ll probably continue to buy your ink, paper and other products from that store in the future.

5. What Software is Included?

The last secret of buying a new computer has to do with the software that is included. Most new computer systems include quite a few programs and sometimes the value of the software can be quite high.

Something to watch out for when looking at the included software is “trial versions” or “limited editions”.

Many programs that are preloaded are either crippled versions that don’t have all the features of the full program, or trial versions that will only run for a certain amount of time before they expire.

Computer are often sold with trial versions of the following types of software:

• antivirus
• firewall
• MS Office or other office suites
• Accounting – both business and personal

The computer manufacturers generally don’t make it easy to tell whether the software on their systems are trial versions or limited versions. This is a question that you should specifically ask if you can’t find the answer in their promotional information.

If you’re buying a new computer with trial versions of the software, keep in mind that you will need to pay to continue using it after the trial period is over. This is an added cost that you need to consider as part of your overall budget.

These five “secrets” of buying a new computer are fairly common sense, but they are not always made clear up front. Knowing what to ask will help you in two ways. First, you can be sure you are getting the right computer for your needs.

Second, if the salesperson or company that you’re dealing with explains these things to you without being asked, you’ll know you’re dealing with someone who is honest and upfront.

Knowing you can trust the people you’re dealing with is an invaluable feature of your new computer system.

Spyware is the most troublesome software to appear on the Internet in recent times. When spyware infects a computer system, it may be relatively harmless or it may be devastating.

What Is Spyware?

Spyware is any software that collects information about computer usage and/or the computer user. It is installed on one computer and sends information to another computer. Some spywares like the Weather Bug, Bear Share and Kazaa are knowingly downloaded and installed by users. Other spyware is installed without the knowledge or permission of the user.

How Does Spyware Affect A Computer?

Symptoms of spyware infection includes:

• Very slow system performance while browsing the Internet.
• Your homepage changing mysteriously on its own.
• Excessive appearance of pop-ups, on sites likes Google, Yahoo and MSN, which don’t use them.
• You can only get your browser to visit sites, which are trying to dupe you into buying spy ware removal software.

Many spyware detection and elimination programs are easily available for free on the Internet.

How Does One Deal With Spyware?

There are many tools and catalogues available to deal with spyware. One of these tools is Spybot Search and Destroy. It scans computers for spyware and harmful programs. It shows a list of problem areas to the user and allows him to delete any or all of them.

A user can leave legitimate programs installed by him. These may include peer-to-peer file sharing software or software installed to monitor the on-line activities of children.

A Comprehensive Solution

It may be a good idea for most computer owners to get a comprehensive PC security solution as a bundle. Norton and McAfee, now offer a complete security suite consisting of anti-virus, personal firewall, anti-spam and privacy offerings, and anti-spyware.

They are quite easy to install and allow parents to monitor children who use the computer. There are many threats on the Internet, from which these suites can protect your computer.

Holiday travelers should be on alert when arriving home from long weekends, such as the Fourth of July, a popular time for computer viruses to spread.

Most computer users have a tendency to turn off their computers when away on trips, which means you’re not getting newly released anti-virus patches or anti-spyware updates; the two most common areas that cause computers problems. We recommend you update anti-virus and anti-spyware scans before opening e-mail or going online after an extended absence.

We consistently see an increase in calls for virus related problems immediately following long weekends. Avoid the problems altogether by updating your security software before using your computer.

2. Should You Leave Your Computer Running?

One question we hear frequently is, “Should I leave my desktop computer on or turn it off?”

There are 2 schools of thought

Turning it on and off numerous times during the day subjects the microcircuits to flexing and fatigue due to change in temperatures. Over time this could lead to a break in the circuitry and result in system failure.

Leaving the computer on all the time puts excess wear on the mechanical components (the hard drive spindle motor and cooling fans).

Best compromise. First user in the morning turns it on; last user turns it off.

We leave our desktops on all the time allowing for scheduled utility tasks to run during overnight hours. We also restart the systems (to flush the RAM and reset the operating system) on a regular basis and routinely remove the case covers to clean out any dust that may have accumulated, especially around the fans and screens.

3. Stop Popups!

Never click inside the window of a popup. Instead, close it by clicking on the X in the upper right corner. Many people are fooled into installing spyware applications by popups that promise to clean their system. If you receive a message saying it can help, assume it’s spyware and don’t click.

Having a corporate or promotional video for your company is often viewed as something of an expensive luxury useful, but rarely considered to be an essential marketing tool. Whilst many businesses can understand the benefits of having a corporate video, all too often they are put off by the perceived cost and subsequently find it hard to justify commercially. Furthermore, the process of making a video can at times, appear complex and intimidating, with an array of technical terms and processes.

Streaming video provides a number of useful opportunities for maximising the potential of an existing corporate video. And compared to other distribution media such as DVD or CD-ROMs it also offers a cost effective solution for broadcasting a new corporate presentation to a wider audience.

Although streaming video is certainly not a new concept and has been around for some time, it’s now easier than ever to add streaming video content to your website. The technology required to enable video streaming is widely available, it’s relatively inexpensive and with the dramatic growth in high speed, broadband internet connections, a growing number of internet users can now view high quality, streaming video on their computers.

Provide Compelling Content

Try to provide content that creates a real interest for the viewer. Instead of simply informing them of your key corporate values, the typical narrative being ‘how successful we are, the great products & services we offer, our featured clients’ why not turn the message into something that is actually useful and engaging to watch.

Take for example a company that manufactures kitchen products. Whilst you could produce a video to establish company values by highlighting such areas as quality of craftsmanship and original design of the product, this information is almost certainly available more easily on the web pages. It could be far more interesting for the viewer to provide them with a series of recipes, which feature the products being used in context.

Another technique is to provide content that is not centrally focused to your company’s core products & services. For example, your company sponsors a sports event or art exhibition. How about showing some clips from the event, with company branding around it? By using more recognisable and popular content, you are creating a wider ‘reach’ for the video, with the added possibility of gaining increased website traffic.

Re-Package Content

Lets say you already have a corporate video, it’s around ten minutes long and you currently distribute it on a video tape format or DVD. The most obvious solution would be to have it transferred to a streaming format in it’s entirety and loaded up onto your website. Whilst a ten minute corporate video sequence may be useful as a backdrop display in a trade exhibition or screened to a captive audience in a conference, it’s often far too long to use as a streaming video clip on your website. Who really has the time to sit and watch a corporate video clip for this length of time? It’s often far more useful to break the sequence down into a series of individual clips or re-edit into a shorter, condensed version that has greater impact.

Following on from this, you might also want to distribute streaming video clips around different areas on your website. This way, the clips featured can be targeted to match and complement the page content. For example, on a page detailing company clients and case studies, the video clip could feature customer testimonials; situated on a contact details page, the video sequence could feature some generic shots of company locations and building exterior shots.

Brand The Video

Whatever streaming video clips you use, try to ensure they are branded with your corporate identity. This could be a small logo in the top corner of the screen or a ‘picture frame’ wrapped around the moving images. Taking it a step further, you may want to add an introduction sequence with animated corporate logos at the beginning and end of every sequence. Another option is to create an HTML or Flash ‘player’ customised with your corporate identity. The video clip would then play within this frame and could be complemented by some animated product or service information around it.

When reviewing website statistics, it is frequently pages featuring streaming video content that are the most ‘sticky’ and have the longest viewing times by site visitors. Use this factor to your advantage, it’s an ideal opportunity to get your core brand values, products and services across to the site visitor.
