Computer caches are memory circuits that serve to speed up a much larger memory drive. In a typical computer it takes the microprocessor 60 nanoseconds to access the RAM. To cut the time it takes for the microprocessor to access data from the RAM, a special memory bank or memory circuit is installed into the …
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 …
The Universal Serial Bus (USB) interface connects peripherals in a variety of ways. These peripherals include the standard and non-standard computer mouse, keyboards, gaming controllers, scanners, printers, digital cameras, hard disks, CD/DVD-Rom drives, card media devices, music devices, speakers, and networking components. A variety of other devices that use USBs as well as devices that …
If you have ever wanted to display the same image or video on two or more separate monitors, you can understand the need for a VGA splitter. VGA splitters are great for home theater projectors that are used in classrooms and home theaters as they allow you to continue using your desktop while you fiddle …
EEPROM stands for Electrically Erasable Programmable Read-Only Memory. An EEPROM is like an EPROM chip since it can be written in or programmed more than once. Unlike the EPROM chip, however, an EEPROM chip need not be taken out of the computer or electronic device of which it is part when a new program or …
SCSI (Small Computer System Interface) is a set of ANSI standards for connecting devices to computer systems. The vast majority of SCSI devices are data storage devices. Standard SCSI is a parallel technology, but many serial SCSI variants exist, including FireWire and Fibre Channel. SCSI is generally considered a higher-end alternative to IDE (Integrated Drive …
VGA (Video Graphics Array) cables connect computers with monitors or television sets. The cables are based on the graphics standard that IBM developed on personal computers sold during the 1980s. Since that time, almost all personal computers that are built to support the Windows operating system (OS) incorporate support for VGA connections and the more …
A computer’s BIOS (Basic Input/Output System) is software that sets up the operating system by locating various hardware components and telling the operating system how to use them. Updating BIOS will minimize the amount of time it takes for the computer to boot up, correct compatibility issues, and improve the computer’s overall performance. The computer …
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 …
Just like every other technology, video home system (VHS) recording tapes are being affected by technological change. Just as consumers become used to one form of home technology, a new and better technology comes along. Unfortunately, consumers have already recorded many precious moments on their VHS tapes and are increasingly finding that they do not …
