Machine Language - Answer- Binary code made up of 0s and 1s; usually this is data
converted from a high-level language by a compiler. Often used as a synonym for low-
level programming language. (0000 1001 0110 0100 1101 1111 1010 0011)

Bandwidth - Answer- Transfer rate permissible over the media, described as some
number of bits per second (bps)
Network hub - Answer- A device that connects multiple computers into a network.
Network Switch - Answer- More functional connection than a hub. Its purpose is to only

Router - Answer- A device that connects multiple networks together; routes packets to
their next location in order to efficiently reach their destination.
Wireless Access Point (WAP) - Answer- Connected to a hub, switch, or router. Sends
out a wireless signal so computers on the network can connect without a cable.
Circuit Switched Network - Answer- Requires that a full pathway, or circuit, be est.
before transmission can begin and maintained during the entire transmission.
