Identify the characteristics of TCP from the list below. Explain each of the characteristic you identified.
- Manages the data transfer.
- Support for error checking.
- Establishes network connection.
- Finding shortest path.

Answer:

a) Support error checking.

TCP is transfer control protocol. It conrol reliability using error error controls include mechanism of correcting errors after they are detected. It uses 3 simple tools :

1.Check sum : used to check a corrupted segment.if sigal is corrupted and disgarded by destination of TCP.

2.Acknowledgment: It is used to confirm the receipt of data segments.

3.Retransmission: It is the heart of the error control mechanism.when a segment is delay or lost it retransmitted.
