The Divestiture of AT&T and the Telecommunications Act of 1996 had a major impact in the United States. The Divestiture of the Bell Operating Companies from AT&T was one of the critical events of the 1980s that continues in importance today.

Give a brief description of the rationale for divestiture, how it relates to the AT&T Consent Decree and other legal actions, and recent consolidation in the industry.

Build a matrix of three pro and three con arguments concerning the break-up of AT&T.

Layer Two: controls access and handles errors.

Describe three access control methodologies.

Describe the techniques in Layer 2 that Prevent errors.

Describe the methods in Layer 2 that Control errors.

Draw how a series of FOUR separate messages would be successfully sent from one computer to another using ARQ if:

the first message was transmitted without error

the second message was initially transmitted with an error

the third message was initially lost

and the ACK for the fourth message was initially lost.
