administrators in the early 1990s, but
fell out of popularity in favor of the
very similar, but higher performing,
Category 5 cable standard. Since the
early 2000s most new structured
cable installations are built with Cat
5e or Cat 6 cable.

Category 4 Cable(Cat4)
is a description of a cable that consists of
four unshielded twisted-pair (UTP) copper wires
with a data rate of 16 Mbit/s and performance of
up to 20 MHz. It was used in token ring networks,
10BASE-T, 100BASE-T4, and is no longer common
or used in new installations. It is used in
telephone networks which can transmit voice and
data from 12 Mbit/s to 16 Mbit/s.

Category 5 cable (Cat 5)
is a twisted pair cable for carrying signals.
This type of cable is used in structured cabling for
computer networks such as Ethernet. It is also
used to carry other signals such as telephony and
video.

Category 6 Cable(Cat6)
cable, commonly referred
to as Cat 6, is a cable standard
for Gigabit Ethernet and other
network physical layers that
is backward compatible with
