TCP/IP = Transmission Control Protocol / Internet Protocol

Purpose in network communication

TCP/IP is actually a pair of protocols that work together, each handling a different part of the job of moving data across a network:

• TCP (Transmission Control Protocol):

  • Breaks the data to be sent into smaller units called packets.
  • Ensures reliable, ordered delivery — it checks that every packet arrives, requests re-transmission of any lost packet, and reassembles the packets in the correct order at the receiving end.
  • Establishes a connection between sender and receiver before data transfer begins.

• IP (Internet Protocol):

  • Handles addressing and routing — every device on the network has an IP address, and IP is responsible for finding the best path and delivering each packet to the correct destination address. …
