Q6. In modems that support more than 300 baud, baud and bps do not mean the same thing.

A. TrueB. false

Q7. "bps" stands for bits per second. Baud is the number of discrete signals per second One discrete

signal can encode more than one bit. Hence, a 9600 bps modem actually operates at 2400 baud.

However, in common non-techie terminology, baud and bps are used synonymously, though that is not

technically correct. These are all true statements.

A. TrueB. false
