.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. This is known as bandwidth. Channels with high bandwidth are known as broadband - while channels with low bandwidth are known as ___________.
Bus
Transmitter clock
Communications
Narrowband
2. ___________ communication lets you send and receive at the same time.
Bus
Full duplex
Asynchronous
Transmitter clock
3. Bandwidth is the amount of data that can be sent over a ______________ channel line in one second.
Parallel
Parity [Explanation: With an even parity protocol - it would either add a 1 - to make the byte have an even number of 1 bits or a 0 if the byte already has an even number of 1 bits. With an odd parity protocol - it would either add a 1 - to make the
