DRAM
Dynamic random-access memory (RAM). Referred to as "dynamic" because it
must be regularly refreshed, unlike SRAM, which retains a value as long as
power is supplied. See also RDRAM and SDRAM.
DRDRAM
Direct Rambus dynamic random-access memory (RDRAM). Provides a 16-bit
bus, rather than the 8-bit DRAM bus. At a speed of 800 MHz, the peak data
transfer rate is 1.6 billion Bps. DRDRAM uses pipelining to accelerate
processing, allowing up to eight operations to be performed simultaneously.
DTE
Data terminal equipment. In computer data transmission, DTE is the RS-232
interface that a computer uses to exchange data with a modem or other serial
device. See also DCE.
