Power Supply for Home Server Computer

0 comments
This project describes a home made power supply for a small server computer. It uses a toroidal power transformer (not the conventional transformer) to step down the mains AC voltage. The advantages of using a Toroidal is it is quiet, efficient and smaller in size. The transformer output is then rectified and capacitive filtered. DC regulation is achieved using PTN78020 for the 12v supply, and PTN78000 for the 5V one.

Video Card Driver Problems

0 comments
If you have outdated or corrupt video card drivers you will find it impossible to enjoy your computing experience. You may notice poor graphics, lock ups in the work of program use or even no graphics at all. The video card driver work as a bridge to communicate with the card itself, so if the drivers go bad it is like speaking on a mobile phone with poor reception, choppy, broken up and impossible to deal with.

Troubleshooting Video Card Driver Problems

You can find diagnostic tools such as Windows Aero troubleshooter. You can find this through your Start menu or if it is not installed on your process, go to Microsoft is Support page and find it under the Fix it tab. The program will scan your systems hardware and find any missing or corrupt drivers that require to get replaced.

Plenty of times when you install a new video card or a new operating process you will run in to issues with outdated, missing or corrupt drivers. Viruses can be the reason for a missing or corrupt driver as well, some viruses will often be named as an important file on your process and replace the actual with the false.

You can get missing or updated video card driver by visiting the manufactureres web-site directly. You will require to know the operating process you are jogging , the name and model of the video card installed and sometimes the type of monitor you are using, either CRT or LCD.

If you have no idea what type of video card you have installed, you can find out by following this process . 

  • Go to Start
  • Open Control Panel
  • Click Appearance and Personalization
  • Select Personalization
  • Click Display Settings
 This will display not only the information on the video card you have installed but the monitor information as well.
It can be tedious installing the updated driver by yourself. The best way to put in it is to save it to a folder on your desktop so it is basically located & go to the tool manager & then the properties of the video card & click update driver. This way you can have it follow the path you select to locate the driver you downloaded. Some manufacturer sites offer automatic installation of the drivers, where you click it to download & it will install itself after it is opened.

memory, information

Random Access Memory (Ram)

Random-access memory is a kind of data storage for computers. Often known as the acronym RAM or basically memory, random-access memory details the speed in which data that are stored can be accessed at random. This means that the strength of the RAM determines, at random, how fast a piece of data can be pulled & returned. Regardless of where the data is on a drive or whether it is at all related to any earlier bit of data is irrelevant; RAM pulls it back at a constant time.
AM differs tremendous from other types of storage devices such as optical discs. These depend on the consistent movement of the medium in which information has been recorded. For example, a DVD player needs to have the DVD within to read the information. The downside to this is that it takes longer than an information transfer, but more importantly, based on where the information is physically in relation to the earlier minuscule bit of information determines the speed in which it's recovered. Because of this, RAM is faster at obtaining information than optical or magnetic discs. Their use, though, is in the fact that the information doesn't must be stored on the actual drive.

Types of RAM

  • SRAM: Static random access memory has anywhere from four to six transistors for each memory cell. Because it doesn't have a capacitor for each cell, its primary use is for caching.
  • DRAM: Dynamic random access memory gets its name because it consistently needs to be refreshed. It has memory cells that have a transistor and capacitor pair.
  • FPM DRAM: This is known as fast page mode DRAM which is the original type. For each process – 0 or 1 – it goes from column to column and row to row to find the data. This slow speed allows for a max of 176 MBps.
  • EDO DRAM: Extended data-out DRAM goes faster than its predecessor because it doesn't wait for the first bit of data to be found before it begins finding the second bit. This means it has a max transfer rate of 264 MBps.
  • SDRAM: Synchronous DRAM is the most common used RAM in today's computers. Because it understands the principle that most CPU will have the data in sequence, it stays on one row containing a needed bit and then checks each column. This increases the transfer speed up to 528 MBps.
There are faster types of RAM, but the main point is that speed is based on how the RAM finds information. Therefore, when there is more RAM in a pc, it suggests that information can be found at a great speed which begs the final query: how much RAM do I require? The answer to that is simple. What are you going to do together with your machine? Most people suggest getting more if it is feasible & since upgrading RAM is usually cheap, getting more should not be looked down on. A faster machine means things are done more efficiently.
Read only Memory (Rom)
Because information is fully incorporated at the ROM chip's manufacture, information stored can neither be erased nor replaced. This means permanent & secure information storage. However, if a mistake is made in manufacture, a ROM chip becomes unusable. The costliest stage of ROM manufacture, therefore, is generating the template. If a template is obtainable, duplicating the ROM chip is very easy & affordable.
Read-Only Memory or ROM is an integrated-circuit memory chip that contains configuration information. ROM is often called firmware because its programming is fully embedded in to the ROM chip. As such, ROM is a hardware & program in one.
A ROM chip is also non volatile so information stored in it isn't lost when power is turned off.

RAM versus ROM

Both RAM plus ROM provide the user random access to stored information. However, RAM provides only short-term memory since information stored in RAM is lost when power is turned off. ROM, on the other hand, provides long-term storage since information is permanently etched in to the ROM chip.
One other difference between the two is that RAM's information can often plus speedily be altered plus changed at will. ROM cannot be reconfigured at all.

ROM Chip Manufacture

The ROM chip has a matrix of columns and rows. The point of intersection between the column and the row is called a cell. Each cell will have a value of either 1 or 0. The manufacturer of the ROM chip has to select each cell's value before the ROM manufacture ensues.
After the program has been designed, the ROM chip can now be made. At each cell where the worth ought to be 1, a diode is placed to connect column to row. At each cell where the worth ought to be 0, no diode is placed.

The ROM Chip's Diode

The diode has a maximum voltage requirement, what is often called the forward breakover, which needs to be surpassed before the diode will transfer the charge from the column to the row of the cell. The usual ROM diode forward breakover voltage is around 0.6 volts.
The diode is the cell's electronic check valve. Its main function in the ROM chip is to control & direct the flow of electrical current in cells. Specifically, it transfers the electrical current from column to row.
The ROM activates cells by sending through voltage that is over the cells' diode forward breakover. The charge that is directed through the column gets passed on by the diode to the appropriate grounded row. Since charge is successfully transmitted from column to row, the cell where a diode is present has a value of 1.
In the ROM circuit, passing a charge through the column won't affect the cells whose values are supposed to be 0. In any cell, this charge cannot be passed from column to row if there is no diode to facilitate the transfer. Therefore, once a cell's value has been determined to be 0, it will permanently be 0 .

Your Computer is Slow?

There are lots of reasons why your computer may be jogging slower than normal. of the main causes is your systems registry. The registry in your computer is the systems main brain & stores everything you do. So, every action you take on your computer from turning up the volume to downloading a program makes an entry in the registry.

Over time your registry becomes bloated or even corrupt. In the event you uninstall programs without using the uninstall feature you will finish up with left over fragments of the program in your registry and this can generate an issue with speed as well as how your technique functions. Malicious program is another cause of a corrupt registry. In the event you surf the web chances are you have been infected with some kind of malicious program. Adware and adware are common and sometimes missed by your antivirus program, but viruses and Trojans are common as well for those who download files from the web. You can run your antivirus program to try to remove the malware from your technique but in lots of cases it will still have fragments left behind in the registry.

 The best way to deal together with your registry issues is to download a registry cleaner. Trying to mess together with your systems registry by yourself can be not only tedious, but dicy as well. You do not need to chance making a mistake that will fine-tune how your technique works, so let the program do it for you. Always be definite that you use the backup option in the program before you make any changes to your registry, in case the program removes something you might have needed. If after cleaning the registry of all errors you still notice your technique being slow, you may need to think about storage space, memory issues or even malfunctioning hardware as the cause.

Definition of a computer

A computer is an electronic machine that uses a set of instructions that are stored in its memory unit, to do many kinds of jobs.
A computer accepts data from an input device (keyboard,mouse etc )and processes it into useful information which it displays on its output device ( monitor,printer etc )



Actually, a Computer a collection of hardware and software components that help you do many different task.

A computer can do math it can collect, and display information.
It can help you write, draw, and play games. It also lets you communicate with people all over the world.

Computer cannot think. A computer makes decisions based on simple comparisons such as one number being larger than another.
Although the computer can help solve variety of problems,it is simply a machine.
It cannot solve problem on its own.
Computer comes in different size and models . A small computer is called a microcomputer. It is also popularly known as a personal computer or PC because it is normally used by only one person at one time .
Here are some examples of computers.
