Business Data Communications Exam 1
computer network - ANS-An interconnected group of computers and computing
equipment using either wires or radio waves that can share data and computing
resources.
wireless - ANS-Computer networks that use radio waves and can involve broadcast
radio, microwaves, or satellite transmissions.
personal area networks (PANs) - ANS-Networks spanning an area of several meters
around an individual include devices such as laptop computers, smart cell phones,
music players, and wireless connections.
local area networks (LANs) - ANS-Networks that are a little larger in geographic size.
Spanning a room, a floor within a building, or an entire building.
metropolitan area networks (MANs) - ANS-Networks that serve an area up to roughly 50
kilometers--approximately the area of a typical city. High-speed networks that
interconnect businesses with other businesses and the Internet.
wide area networks (WANs) - ANS-Large networks encompassing parts of states,
multiple states, countries,
and the world.
backbone network (BN) - ANS-A larger, central network connecting several LANs, BNs,
MANs, and WANs. They provide very high speed data transmission.
data communications - ANS-The transfer of digital or analog
data using digital or analog signals.
interfacing - ANS-Connecting devices to a computer, or a computer to a network.
encoding - ANS-The process of converting data into a format required for a number of
information processing needs.
client/server model - ANS-The client establishes a connection to the server over a LAN
or WAN such as the internet. Once the server has fulfilled the clients request, the
connection is terminated.
