8. In modems that support more than 300 baud, baud and bps do not mean the same thing.
   1. true
   2. false

   Answer :A

9. "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.
   1. true
   2. false

   Answer :A

10. ________ is the term used to refer to the process of two modems establishing communications with each other.
