      CPU (Central Processing Unit)

      CPU is an acronym that stands for central processing unit. The central processing unit is responsible for performing all of the mathematical calculations that are required for a computer to function properly. Because a computer cannot function without the CPU (which may also be referred to as the central processor or just the processor), it

      How Do Quad Core Processors Work?

      A quad core processor is a piece of hardware made up of three components. The first is the core, which in this case, there are four of them. Then these are bundled up and fit inside a die. The die is the silver tab you might see on your processor. Finally, this is added to

    • Hard Disk Partitions

      Hard Disk Partitions

      A hard disk partition is a defined storage space on a hard drive. Most operating systems allow users to divide a hard disk into multiple partitions, in effect making one physical hard disk into several smaller logical hard disks. Reasons to Use Hard Disk Partitions A user may decide to split a hard disk into

      AMD64

      AMD64 is a set of 64-bit extensions to AMD x86-compatible microprocessors. AMD64 extends the industry-standard x86 instruction set architecture while maintaining full compatibility with existing x86 applications. The 64-bit architecture of AMD64 enables applications to utilize up to 256 terabytes of memory, overcoming the 4 gigabytes limitation of 32-bit processors. AMD64 doubles the number of

      How to Repair an Inkjet Printer

      Inkjet printers are cheap but they are still expensive enough to make some repairs worthwhile. There is a surprising number of parts in them, and every part is a potential failure point. The most common failure is a clogged print head. They are notoriously difficult to clean because of their microscopic nozzles. The first attempt

      Blu-Ray

      Blu-ray is an optical storage format developed by Sony and Phillips. It was created to store large amounts of high definition video and sound. Blu-ray’s name came from the type of laser it uses to read and write data. The laser is a hue of blue-violet. A blue-violet laser has a shorter wavelength than the

      How to Measure Sound Quality

      There are many ways to measure sound quality. Many measurements have been created to specifically measure and rate the quality of sound. Here are a few of the most common types of measurements used for sound quality. THD THD stands for Total Harmonic Distortion. It is a measurement taken to view the total amount of

      SVGA (Super Video Graphics Array)

      SVGA is an acronym for Super Video Graphics Array and covers a wide range of computer display standards used in the manufacture of computer monitors and screens. The SVGA standard was designed by VESA, the Video Electronics Standards Association. When using SVGA as a direct comparison to other display standards such as XGA (Extended Graphics

      DASD (Direct Access Storage Disk)

      A DASD, or Direct Access Storage Disk, is a type of storage device that is connected directly to a user’s computer rather than being connected to the network. Because many types of storage device connect directly to a user’s computer, the term “DASD” may apply to a variety of different devices; however, a DASD is

      Address Bus

      The address bus is the set of wire traces that is used to identify which address in memory the CPU is accessing. The number of wire traces in the address bus limits the maximum amount of RAM which the CPU can address. CPU Address Bus Sizes CPU Address Bus Size 8086 20 bit 8088 20
