A measure
of
the speed
at
which data is
transmitted. In personal
computers,
the
baud rate is
equivalent
to bits per
second
.
With serial interfaces, the
printer must be set to receive data at the
same baud rate at
which
the
computer
transmits it.
Binary diglT. Each bit
is either
1
or
0.
A basic unit
of
information consisting of
8
bits. One byte
can
represent any ASCII
character
or
any number between 0
and
256. {Note:
Some
computers
handle
data in
7-bit
units.)
Characters
Per Inch:
A
measure
of
the
width of
characters. Note that
10 CPI
characters are wider
than 17 CPI
char-
acters.
