DMA Direct Memory Access (DMA) enables some peripheral devices to

bypass the system processor and communicate directly with the system

memory.

DIMM Dual Inline Memory Modules are a type of RAM that offer a 64-bit data

bus and have separate electrical contacts on each side of the module.

DIO The digital inputs and digital outputs are general control signals that

control the on/off circuit of external devices or TTL devices. Data can be
