Device Driver

A program that allows for the operating system to support hardware like printers, video cards, sound cards and other devices. You must have the proper device drivers to allow for the device to work properly with the operating system.

(Dual In-line Memory Module) - A printed circuit board with gold contacts and memory devices. A DIMM is similar to a SIMM, but with this primary difference: unlike the metal leads on either side of a SIMM, which are "tied together" electrically, the leads on either side of a DIMM are electrically independent.

(Dual In-line Package) - A DRAM component packaging. DIPs can be installed in sockets or permanently soldered into holes on the printed circuit board. The DIP package was extremely popular when memory was installed directly on the motherboard.

(Dynamic Random-Access Memory) - The most common form of RAM. DRAM can hold data for only a short time. To retain data, DRAM must be refreshed periodically. If the cell is not refreshed, the data disappear.

(Extended Data-Out) - A DRAM technology that shortens the read cycle between memory and CPU. On computers that support it, EDO memory allows a CPU to access memory 10 to 20 percent faster than comparable fast-page mode memory.

(Enhanced DRAM) - Enhanced Memory Systems, Inc. DRAM that contains a small amount of SRAM.

(Electrically Erasable Programmable Read-Only Memory) - A memory chip that retains data content after power has been removed. EEPROM can be erased and reprogrammed within the computer or externally.

(Extended ISA) - A bus architecture that extended the 16-bit ISA bus to 32 bits. EISA operates at 8MHz and has a peak data transfer rate of 33MB per second. EISA was introduced in 1988 as an open alternative to IBM's proprietary Micro Channel bus.

(Erasable Programmable Read-Only Memory) - A programmable and reusable chip that retains content until erasure under ultraviolet light. Special equipment erases and reprograms EPROMs.

(Enhanced Synchronous DRAM) - A type of SDRAM developed by Enhanced Memory Systems, Inc. ESDRAM replaces expensive SRAM in embedded systems and offers comparable speed with less power consumption and lower cost.

(FCRAM) - FCRAM is a memory technology currently being developed by Toshiba and Fujitsu. FCRAM is not intended for PC main memory but will be used in specialty applications such as high-end servers, printers, and telecommunications switching systems.

An early form of DRAM, fast-page mode's advantage over previous page mode memory technologies was faster access to data in the same row.
