UDP (User Datagram Protocol)
Abbreviation of User Datagram Protocol, which is
a TCP/IP transaction protocol used for specific
applications such as remote network management
and naming service access
Unicast
Communication with a station at a single address
(i.e., most general one-to-one communication)
UTP Cable
Abbreviation of unshielded twisted pair. It is a
unshielded pair of wires twisted together, and
these wires are used for Ethernet cabling and
other purposes.
10BASE-T
LAN that uses unshielded twisted-pair (UTP)
cables and complies with the IEEE 802.3
standard. A 10BASE-T connection uses a
concentrator called a hub.
because special cabling work is not necessary
and wiring can be done easily. The maximum
length of cable wiring is 100 m.
100BASE-TX
One of the 100BASE LAN standards (also
called Fast Ethernet), it supports a transfer rate
of 100 Mbps. Other 100BASE standards are
10BASE-T4 and 100BASE-FX, and the differ-
ence is the type of cable used. 100BASE-TX
uses unshielded twisted-pair (UTP) cables. It
also uses the RJ-45 connector, which is similar
to the modular jacks used for telephones.
It is widely used
