Describe TCP and how it provides reliability of packet delivery.
What will be an ideal response?
In TCP/IP, the protocol that guarantees packet delivery is TCP (Transmission Control Protocol). TCP makes a connection, checks whether the data is received, and resends it if it is not. TCP is, therefore, called a connection-oriented protocol. TCP is used by applications such as web browsers and email. Guaranteed delivery takes longer and is used when it is important to know that the data reached its destination. For TCP to guarantee delivery, it uses protocols at the IP layer to establish a session between client and server to verify that communication has taken place. When a TCP packet reaches its destination, an acknowledgment is sent back to the source. If the source TCP does not receive the acknowledgment, it resends the data or passes an error message back to the higher-level application protocol.
