Answer 1

1. A cable connection is a connection between two computers via a physical wire, whereas a wireless connection is exactly what its name is, wireless.

2. Most computers will come with USB1.1, so don't worry about it.

3. Analog transmission is in the form of waves, while digital is in binary form. Usually digital will be the better bet, depending on your needs.

4. Take a look at this page to see the maximum length: http://www.iec-usa.com/Browse05/DTLNGHLM...

Sounds like you DO know about computers, unless this is a homework assignment.
