download. (1) To transfer programs or data from a
computer to a connected device, typically a personal
computer. (2) To transfer data from a computer to a
connected device, such as a workstation or
microcomputer.
DRAM. Dynamic random-access memory.
drive, magnetic tape. A mechanism for moving
magnetic tape and controlling its movement.
Drive Not Configured. This message occurs during
the first boot after a factory settings restore is executed.
This is not a real issue since it takes the library a while
to configure.
DRV. Drive.
DSE. Data security erase.
DSP. Digital signal processor.

server.
Encapsulation Security Payload (ESP). A protocol that
provides confidentiality, data-origin authentication,
connectionless integrity, an anti-replay service (a form
of partial sequence integrity), and limited traffic-flow
confidentiality.
EPO. Emergency power off.
EPROM. Erasable programmable read only memory.
EQC . Equipment check.
