COMPUTER HARDWARE SERVICING NC II BASIC ELECTRONICS: FAMILIARIZING THE RESISTANCE

noreply@blogger.com (zxheejhei) — Thu, 20 Dec 2012 02:22:00 +0000

Resistance

Resistance is the measure of how difficult it is for current to flow through something. And being familiar with resistance, it can help you better understand electronic circuitry. Resistance deals also with current that involves in voltage and with the conductors and insulators. Insulators are those do not easily carry a current like glass, ceramics, woods, and plastics. For best result in resistance study, Good Conductors is the one to deal with. Metal is the good conductor that I am talking about. Current can easily flows trhough metals that’s why plastics is used as cover for metal wires to be its insulator. Now how about the Silicon and Germanium? They are called “the semi-conductors” which fall between conductor and insulator.

Size also reflects the resistance. A thick metal wire can produce lower resistance, likewise shorter wire the shorter the resistance. To have a higher resistance you need to have a longer wire.

Resistors

More of circuits nowadays often carry small amount of power that’s why resistors born. If the resistor carries higher value of resistance, then if a voltage placed across it, the less current will flow through it. To get the value of the resistor, color code is need to be read or else you need a multitester to get the amount of resistance into it. The unit for this time is “Ohms”, a very small size. Ohms is named after German physicist George Simon Ohm.

Resistor Color Coding

0 Black

1 Brown

2 Red

3 Orange

4 Yellow

5 Green

6 Blue

7 Purple/Violet

8 Gray

9 White

Reading the Color Codes

Mose of the resistors composes of 3 color bands. The first and the second band is the number and the third is the number of noughts. See example below:

Computer Hardwrae Servicing NC II Basic Electronics: Familiarizing the Voltage

noreply@blogger.com (zxheejhei) — Thu, 20 Dec 2012 02:19:00 +0000

Voltage

To understand what electronics is, you need to know first, what is voltage. All we know that if there is no Voltage, electronics is non sense. Yet, we know all about this, if not , this article can help you.

Let us say I have a battery in my hand. Does the battery have voltage? Yes, it has. The batteries have voltage between its terminals. This voltage helps the Current to flow through any electrical circuit placed across it. If there is a current flow into the circuit, you will see some happenings like a bulb produce light, you can create heat, sound, movement, magnetism, sparks and etc.

How to Test the Voltage

In able to test the voltage or the amount of voltage, we need a Voltmeter or the Multitester. Take note that the unit used for voltage is “Volts” named after Voltaire, the man who introduce voltage in the human history. Multitester or Voltmeter can help you to figure out how big or small is the amount of voltage. The bigger the voltage, yet, the bigger the current flows into the circuit. Let us get back to the battery. We can see that there indicators, the Positive (+) and the Negativ (-). Those are what we called the polarity. In using Multitester for testing the voltage of the battery, set your point to DC (Direct Current) section. This tester is having two wirings colored Red and Black (Most of All). The Red indicates the positive and the Black indicates the negative. To begin the test, put the Red wire with pin into the positive part of the battery and Black on the negative part. You can see that the metter indicator on the Tester move from left to right, it means that there is voltage and if the meter don’t move a bit, it means that there is no flow of current. Shown below is the picture of testing the voltage of a battery.

Top 10 PC Optimization Technique for Old Computers

noreply@blogger.com (zxheejhei) — Tue, 18 Dec 2012 20:39:00 +0000

Optimization helps you to speed up your computer. If your computer is well optimized you can do many things without interruption. It can make your work be easy most specially in typing jobs or any related work. More of us wants to have a high end computer but not affordable with our budget. That's why we are still making sense of our old computer or let us say not a high end one like P4, PM and Sempron processor inside the system unit and only having 512 MB of RAM. What I want to say is, there is a way on how to optimize computer/PC without upgrading. Office works, is what I meant, for what I have in the said old computer. Not only for that, also with the students who cannot afford to buy a new one. Listed below are the ways on how you can optimize your PC without upgrading.

1. Check Up - I can say that computers are like humans that needs care also. If a human got sick he/she goes to a doctor for check up. Computers need check up too, and you will be the doctor. Checking up all the peripherals inside the system unit can help a lot that we can say diagnose. Now once the computer diagnosed or checked up already, and if you found somethings wrong, you are now going for troubleshooting. Although you can not totally fix the problem, at least you knew what are the problems on your computer. On that time you can call a Computer Technician or any specialist to fix that problem.

2. Anti - Virus - like what I have said computers are like humans, viruses can destroy the system system of the human body like in computers it will destroy your files and other system files. Make sure that you have installed Anti-Virus and keeping it updated. How if I can't buy that kind of Anti-Virus. In the internet, there are lots of freeware Anti-Virus software that you can download. Or you can visit the Freeware Download Link on the Page menu on this Blog. Keeping your PC Virus free helps you a lot in maintaining the good performance of your PC. Always scan your system for Viruses.

3. Unused Programs - delete some unused programs for the system not to be crowded. Make sure that the file is not important. Take a look first before deleting them.

4. Start Up - disable programs that are not needed to be run on system start up. Enable only the important applications like Anti-Virus.

5. Cleaning - you can clean the PC outside and inside. Outside is for physical cleaning, uncasing the unit and clean the whole PC. Inside is for cleaning the disc storage, the registry, cookies, recycle Bin, and any temporary files. CCleaner can help a lot with this one.

6. Updates - updating your computer system can also optimize your PC. Take advantage of that.

7. Proper Shutdown - improper shutting down of the system unit can give the Hard Disk Bad Sectors and also System Crash. Make sure that you will always shutdown your PC properly.

8. Defragmentation - fragmented files can make your PC slow down. Defrag your Hard Disk to arranged those fragmented files.

9. Virtual RAM - this is an advance technique. You can read the whole process Here.

10. Graphics - minimize using of screensavers and other desktop enhancers. It can also affects the CPU performance.

BIOS Familiarization for Computer Hardware Servicing NC II Students (BASIC)

noreply@blogger.com (zxheejhei) — Mon, 17 Dec 2012 17:21:00 +0000

The read-only memory BIOS provides a intrinsic Setup program that permits the user to change the fundamental system configuration and hardware parameters, Bios may be a set of routines that affects however transfer information between computer parts, like memory, disk, and also the display adaptor. The changed information are going to be hold on in an exceedingly battery-backed CMOS, in order that the info are going to be preserved even once the ability is turned-off. In general, the knowledge saved within the CMOS RAM can keep unchanged unless there's a configuration amendment within the system, like disc drive replacement or a tool is side. During this model we tend to are mistreatment recent form of BIOS version, appearance can disagree on some Machine model particularly for the newer models.

How to get inside the BIOS Settings?

As a computer technician, based on my experiences, hitting the key on keyboard is the easiest way to get into the BIOS. Now, what are the keys? The keys depends on the types of BIOS or models you are entering with. Most used are, F2 and Del key that almost works in most of BIOS'. The F9 key almost goes to Load Optimized Defaults and F10 for Save and Exit.

THE GRAPHICAL USER INTERFACE

The Main Menu

CMOS Features

-commonly used for configuring Hard Drive Channels, Date, Time, Floppy Mode and Halt On.

The Advance BIOS Features

- deals with the booting process which is needed to be prioritize and for configuring various parts of your system unit.

Best Understanding and Identifying about RAM (Random Access Memory)

noreply@blogger.com (zxheejhei) — Mon, 17 Dec 2012 15:39:00 +0000

(Useful Term for Student of Computer Hardware Servicing NC II)

RAM (Random Access memory) basically known as the Computer Memory or Computer Data Storage. It allows keep information to be accessed in terribly nearly an equivalent quantity of your time for any storage location, thus information is accessed quickly in any random order.

There are two main types or forms of RAM; the SRAM (Static RAM) and DRAM (Dynamic RAM). SRAM is a form of RAM that is costlier to provide, however is usually quicker and needs less power than DRAM and, in trendy computers, is usually used as cache memory for the electronic equipment While DRAM stores a bit of data using a transistor and capacitor pair, which together comprise a memory cell. To read more about basics on RAM click here.

Different Versions of RAM

1. SDRAM (Synchronous Dynamic Random-Access Memory) - is dynamic random access memory (DRAM) that is synchronized with the system bus. Classic DRAM has an asynchronous interface, which means that it responds as quickly as possible to changes in control inputs. SDRAM has a synchronous interface, meaning that it waits for a clock signal before responding to control inputs and is therefore synchronized with the computer's system bus. The clock is used to drive an internal finite state machine that pipelines incoming commands. The data storage area is divided into several banks, allowing the chip to work on several memory access commands at a time, interleaved among the separate banks. This allows higher data access rates than an asynchronous DRAM.

2. DDR SDRAM (Double Data Rate Synchronous Dynamic Random-Access Memory) - is a class of memory integrated circuits used in computers. Sometime referred to as DDR1 SDRAM. Compared to single data rate (SDR) SDRAM, the DDR SDRAM interface makes higher transfer rates possible by more strict control of the timing of the electrical data and clock signals. Implementations often have to use schemes such as phase-locked loops and self-calibration to reach the required timing accuracy.

Source: http://en.wikipedia.org/wiki/DDR_SDRAM

3. DDR2 SDRAM (Double Data Rate Synchronous Dynamic Random-Access Memory) - It supersedes the original DDR SDRAM specification and has itself been superseded by DDR3 SDRAM. DDR2 is neither forward nor backward compatible with either DDR or DDR3.

In addition to double pumping the data bus as in DDR SDRAM (transferring data on the rising and falling edges of the bus clock signal), DDR2 allows higher bus speed and requires lower power by running the internal clock at half the speed of the data bus. The two factors combine to require a total of four data transfers per internal clock cycle. With data being transferred 64 bits at a time, DDR2 SDRAM gives a transfer rate of (memory clock rate) × 2 (for bus clock multiplier) × 2 (for dual rate) × 64 (number of bits transferred) / 8 (number of bits/byte). Thus with a memory clock frequency of 100 MHz, DDR2 SDRAM gives a maximum transfer rate of 3200 MB/s.

Source: http://en.wikipedia.org/wiki/DDR2_SDRAM

4. DDR3 SDRAM (Double Data Rate Synchronous Dynamic Random-Access Memory) - is a modern kind of dynamic random access memory (DRAM) with a high bandwidth interface, and has been in use since 2007. DDR3 SDRAM is neither forward nor backward compatible with any earlier type of random access memory (RAM) due to different signaling voltages, timings, and other factors.

DDR3 is a DRAM interface specification. The actual DRAM arrays that store the data are similar to earlier types, with similar performance.

Source: http://en.wikipedia.org/wiki/DDR3_SDRAM

5. DDR4 SDRAM (Double Data Rate Synchronous Dynamic Random-Access Memory) - is a type of dynamic random-access memory (DRAM) with a high bandwidth interface expected to be released to market in 2012. It is one of several variants of DRAM which have been in use since the early 1970s. And is not compatible with any earlier type of random access memory (RAM) due to different signaling voltages, physical interface and other factors.

How to repair No Display Desktop Computer?

noreply@blogger.com (zxheejhei) — Fri, 14 Dec 2012 12:41:00 +0000

No display computer can be categorized by different problems that occurs. First you need to check all the possibilities why computer having no display. This moment I will show you some of my experiences and how do I fixed it.

Power Supply

I have encountered on one of my costumers system unit that almost all of the primary peripherals are replaced but still the computer or PC is having No Display. But in the end when I replaced the Power Supply Unit (PSU), boom, it displays again. Not easy to believe but it's true.

Monitor

1. Is the monitor having power? If not, try to check the power cable or adapter.
2. If having power then check if the VGA or DVI cable is properly plugged. Sometimes there is a loss of connection.
3. Cable is good, now still no display. For this time, get a flashlight and take a light on the screen and look for any pictures or images on black area of the monitor.
4. If you can't see anything it means wee need to try replacing the monitor.
5. If still having no display proceed now to System Unit.

System Unit

1. Open the side cover of the casing and look for the Memory or RAM.
2. If you are using 2 RAM, take out the one and turn on the PC.
3. Still no display? Now take out the last RAM and put again the other one.
4. Again No Display, remove all the RAM, get an eraser and clean the gold section of the RAM.
3. Put again the memory on the slot and turn on the PC.
4. If still no Display, Replace the RAM with the new one.

You need also to check all the peripherals inside like Video Card, Processor, Hard Disk and Motherboard one by one.

PROTECT IP Act (Preventing Real Online Threats to Economic Creativity and Theft of Intellectual Property Act, or PIPA)

noreply@blogger.com (zxheejhei) — Thu, 13 Dec 2012 18:57:00 +0000

While surfing the internet I found this video below that get my attention. It tells about censoring the Internet. No! PIPA or (Protect IP Act) is dangerous. Let us stop it! Most of the popular Internet Companies are dealing with it. Let us vote now for the future! Sign the petition.

Content of the letter for voting:

I am writing to you as a voter in your district. I urge you to vote "no" on cloture for S. 968, the PROTECT IP Act, on Jan. 24th. The PROTECT IP Act is dangerous, ineffective, and short-sighted. It does not deserve floor consideration. I urge my representative to vote "no" on SOPA, the corresponding House bill.

Over coming days you'll be hearing from the many businesses, advocacy organizations, and ordinary Americans who oppose this legislation because of the myriad ways in which it will stifle free speech and innovation. We hope you'll take our concerns to heart and oppose this legislation by voting "no" on cloture.

Best Way On How To Install Windows 8 Using USB or Flash Drive

noreply@blogger.com (zxheejhei) — Tue, 11 Dec 2012 18:54:00 +0000

We all know most specially with the computer technicians that not all of system units are having Optical Disk Drive like Netbook, unless you are going to use an external ODD. It means that we are going to have an alternative way on how to install Windows 8 without the use of Optical Disc Drive. Let us talk about USB and Flash Drives. Yes, we can use it for installing Windows 8 using it's ISO file, because Microsoft also sold ISO version of the said system (optional). Or else if you have another system unit and if you have only the DVD copy make an image of it using either of the following: Power ISO, IMGBurn, or Magic ISO.

Requirements:

1. At least 4GB Flash Drive
2. ISO file of Windows 8
3. Windows 7 USB/DVD Download Tool (Click Here)

Note: Windows 7 USB/DVD Download Tool Also Works in Windows 8

Procedure:

1. Format your Flash Drive:

Create Bootable USB Using Wins 7 USB/DVD Download tool as instructed below:

2. Open Wins 7 USB/DVD Download tool and browse for the ISO file.

3. In Step 2-4 : Choose USB Device

4. Make sure that the USB device is properly selected. Then click Begin Copying.

5. The tool can detect if the device is having files, so just make sure it is freshly formatted. Then it will prompt you that all the data in the device will be erased. And click Yes button for continuation.

6. Wait for the process to be finished!

7. Once finished, you can use the USB or Flash Drive by setting it as First Boot on BIOS.

GMER the Rootkit Detector

noreply@blogger.com (zxheejhei) — Sun, 09 Dec 2012 09:57:00 +0000

A ROOTKIT is a stealthy type of software, often malicious, designed to hide the existence of certain processes or programs from normal methods of detection and enable continued privileged access to a computer. The term rootkit is a concatenation of "root" (the traditional name of the privileged account on Unix operating systems) and the word "kit" (which refers to the software components that implement the tool). The term "rootkit" has negative connotations through its association with malware.

Rootkit installation can be automated, or an attacker can install it once they've obtained root or Administrator access. Obtaining this access is a result of direct attack on a system (i.e. exploiting a known vulnerability, password (either by cracking, privilege escalation, or social engineering). Once installed it becomes possible to hide the intrusion as well as to maintain privileged access. The key is the root/Administrator access. Full control over a system means that existing software can be modified, including software that might otherwise be used to detect or circumvent it.

Rootkit detection is difficult because a rootkit may be able to subvert the software that is intended to find it. Detection methods include using an alternative and trusted operating system, behavioral-based methods, signature scanning, difference scanning, and memory dump analysis. Removal can be complicated or practically impossible, especially in cases where the rootkit resides in the kernel; reinstallation of the operating system may be the only available solution to the problem. When dealing with firmware rootkits, removal may require hardware replacement, or specialized equipment.

GMER is an application that detects and removes ROOTKITS. It scans:

hidden processes

hidden threads

hidden modules

hidden services

hidden files

hidden disk sectors (MBR)

hidden Alternate Data Streams

hidden registry keys

drivers hooking SSDT

drivers hooking IDT

drivers hooking IRP calls

inline hooks

How to use GMER?
1. Basically scanning and removing rootkits is the main purpose of GMER. To be able to avail it, download a fresh copy of GMER here.2. Once finished download, run the application.3. Start scanning now.4. If GMER won't start when your computer is infected try to rename gmer.exe to test.exe and open the renamed text.exe.5. To remove the rustock rootkit click >Delete the Service< and answr 'Yes' to all questions.

Dead Pixels on LCD Monitor, How to remove?

noreply@blogger.com (zxheejhei) — Fri, 07 Dec 2012 16:44:00 +0000

Defective pixels are pixels on a liquid crystal display (LCD) that are not performing as expected. Of those, a dead pixel never shows light, and a stuck pixel always shows light (typically red, blue or green), when the device is active. The ISO standard ISO 13406-2 distinguishes between three different types of defective pixels, while hardware companies tend to have further distinguishing types.

Similar defects can also occur in a charge-coupled device (CCD) or CMOS image sensor in digital cameras. In these devices, defective pixels fail to sense light levels correctly, whereas defective pixels in LCDs fail to reproduce light levels correctly.

HOW TO REMOVE

1. Turn off your computer.
2. Get yourself a damp cloth, so that you don't scratch your screen.
3. Apply pressure to the area where the dead pixel is. Do not put pressure anywhere else, as this may make more dead pixels.
4. While applying pressure, turn on your computer and screen.
5. Remove pressure and the dead pixel should be gone. This works as the liquid in the liquid crystal has not spread into each little pixel. This liquid is used with the backlight on your monitor, allowing different amounts of light through which give off different colors.

Spots on LCD Monitor, How to Remove
