piece of hardware, for example a server, which provides backup power
for conducting an orderly shutdown if the server's normal power supply
fails.
Unshielded Twisted Pair. Two insulated wires twisted together with the

pairs. The standard cabling used for telephone lines and Ethernet
10BASE-T.
V
A logical, rather than a physical, LAN that includes workgroups drawn
