ECP
E nhanced C apabilities P ort.
A parallel standard. This
mode is designed for print-
ers. It uses DMA channels,
which reduces CPU over-
head, and also provides a
buffer. The peripheral driver
determines which mode to
use. See
Parallel printer .
EPP
E nhanced P arallel P ort. A
parallel standard. This mode
increases bi-directional
transfer from the Centronics
port 150 Kbytes/sec to be-
tween 600 Kbytes/sec and
1.5 Mbytes/sec. See

External option
An device attached to the

FireWire (IEEE 1394)
A high-speed serial bus devel-
oped by Apple and Texas In-
struments that allows for the
connection of up to 63 de-
vices. Original spec calls for
100, 200 and 400 Mbits/sec
transfer rates. IEEE 1394b
provides 800, 1600 and 3200
Mbps. FireWire supports hot
swapping, multiple speeds on
the same bus and isochro-
nous data transfer, which
guarantees bandwidth for
multimedia operations.
Flash memory
By Toshiba from “in a flash”.
A memory chip that holds its
content without power. De-
rived from EEPROM chip
technology, which can be
