Answer Posted / krishna mohan
TCP/IP is stack of protocols.
TCP operates at transport layer on top of IP layer providing
other features: Ports(multiplexing data among applications),
flow control, sequence control.
Once the ethernet driver has the frame, it sends that to the
data link layer. Depending on the "type" field, the stack
forwards the packet to IP or ARP. IP layer depending on the
"protocol" field, passes it up to the Transport layer, which
supports TCP or UDP.
TCP requires a handshake while establishing and terminating
a connection.
TCP supports:
- Piggybacking of acknowledgment on data
- sliding window protocols with timeouts and retransmissions
- full-duplex, sequenced, byte-stream communication
So TCP takes care of the reliability and guaranteeing
delivery of data.
