Socket 423 is a CPU socket used for early Intel Pentium 4 CPU’s, operating at up to 2GHz. Socket 423, also known as PGA423, is a pin grid array (PGA) socket with 423 pins arranged in a 39×39 matrix with 26×26 pins removed from near the center. Each Socket 423 is 2.1″ x 2.1″ (5.33cm x 5.33 cm). The Socket 423 was used by Intel for less than a year, from November 2000 to August of 2001.  Socket 423 only supported Pentium 4’s built with the Williamette core.  The fastest Read More

Most of us are using Windows PCs and sometimes some of your get into a situation where your floppy drive is randomly accessed every few minutes even though it has no floppy drive inserted. This is not dangerous for a computer system but is off course annoying to almost everyone. This occurs when some program (You are running on your computer, it could be any) considers that something should be written (or backed up) on a diskette. One of the cases, there can be a document in your recent history Read More

How to Rip a DVD Modern technology allows for many different kinds of storage media. Examples of such storage media include CDs and DVDs. Although more advanced means of storage exist (such as external hard drives, USB flash drives, and online servers), CDs and DVDs still provide a fundamental source of information in today’s society. Therefore, it is necessary that users know how to access and transfer data from CDs and DVDs to their computers through a process known as “ripping”. This article will explain how to do so by Read More

A breakout box is a device in which a multi-cable electric line is split into its component cables in order to allow for testing or signal enhancement. There are two main types of breakout boxes. They include breakout boxes that are built to enhance or customize audio or visual signals and breakout boxes that are created to test electronic equipment. Breakout boxes, commonly referred to as BoB's are generally small to medium sized boxes. The smallest boxes can easily fit in a computer's hard drive bay and are usually installed Read More

The most expensive part of buying an inkjet cartridge is the actual cartridge. The ink is much cheaper and therefore, buying refilling your old cartridges rather than buying new ones, you are able to save money that can be used on other things. The only problem with refilling cartridges is that there are so many different types that HP creates, so the plan of attack might vary. For the most part, though, it is the same across the board. Refilling the Cartridge Before you begin to refill the cartridge, make Read More

An SMPS (Switched-Mode Power Supply) is a device that provides power to motherboards in small electronic devices such as laptops and mobile devices. It is often used in situations that require small or light weight components, where an ATX power supply would not be suitable. An SMPS is also capable of a much more efficient transfer of energy, as it is capable of managing voltage and current levels by switching between on and off at fast speeds, rather than simply dissipating extra voltage like ATX power supplies do.   Applications Read More

A VME to PCI adapter is simply a device that is used to send data from one computer component (e.g. server) to another (e.g. peripheral). Here is some more information. What is VME? VME stands for Virtual Machine Environment, developed in the UK during the 1970's; VME was an operating system for main frame computers. Today, newer servers include an updated Unix version called OpenVME. What is PCI? PCI stands for Peripheral Component Interconnect. PCI is a computer bus that is used for connecting peripheral devices to a computer motherboard. Read More

Socket-939 is a 939-contact CPU socket which is used by AMD CPU's, such as the Athlon 64 and Athlon 64 FX. Socket-939 supports a 200MHz system clock and a 1000Mhz HyperTransport link. The Socket-939 is a Pin Grid Array (PGA) Zero Insertion Force (ZIF) socket. A ZIF socket features a lever on one side of the socket. When this lever is pulled up, the spring contacts inside the socket are opened. This allows the CPU to be inserted easily into the socket. The lever is then pushed down, closing the Read More

The Peripheral Component Interconnect (PCI) Express card slots for the x1 devices are small and compact enough to allow an additional peripheral that can be used for low power, low bandwidth, and general additions to the computer system. A PCI express x1 video card provides access to additional graphical power to add one or more monitors to the system. Generally, a video card of this type will provide access to VGA, DVI, S-Video, VHDI, or other possible connectors for additional monitor connections.         Specialized cards that offer Read More

EPROM or Erasable Programmable Read Only Memory was invented by Engr. Dov Frohman. It is a ROM-type chip that can hold data from 10-20 years. It is different from PROM because it can be programmed more than once. An EPROM programming is erased only through exposure to ultra violet light. The EPROM is configured or reconfigured using an EPROM programmer. Configuring an EPROM An EPROM is an array of columns and rows. Each intersection is called a cell and each cell has a floating gate transistor and a control gate Read More
