1. <
hardware> A
type of computer peripheral connector so named
because one side is shorter (with one less pin) than the other
giving a (squarish) "
D" shape. The connectors have two rows
of pins (or holes). Common types are 25-way (13+12 pins) and
9-way (5+4 pins). They are often used for serial lines,
especially
EIA-232.
