Subnet
Subdivision of a network based on IP address. For example, with a
subnet mask of "255.255.255.0," all computers and devices assigned an
IP address starting with "195.172.8" belong to one subnet (there are
255 possible). An IP address starting with "195.172.9" designates a
different subnet.
Subnet Mask
Divides the latter portion of an IP address into subnet and host
designations. For example, in a regular class B network, the first two
numbers in an IP address define the network ID while the last two
numbers define the host ID (the individual computer or device on that
network). A subnet mask changes the format of these last two
numbers by designating the third number as the subnet ID and
designating the last number as the host ID (the computer or device
within that subnet).
SW
Software.
Switch
Device that connects two segments of a LAN. Routes data from one
segment to another based on the MAC address of the destination.
TCP/IP
Transmission Control Protocol/Internet Protocol. Two
communications protocols for the Internet. IP handles the delivery of
data packets over the Internet; TCP ensures that all data packets are
successfully delivered and assembled in the proper order.
Transponder
Component of a satellite that receives radio transmissions from Earth,
amplifies them, and retransmits them back to Earth on a different
frequency.
Twisted Pair
Cable type consisting of multiple pairs of cable in which two wires are
spiraled together to reduce electromagnetic noise. Can be either
shielded (STP) or unshielded (UTP). Used extensively in LANs and
telephone networks.
