Transmission Control Protocol/Internet Protocol(TCP/IP)
The pair of protocols that most major applications use to communicate over the Internet. TCP and IP work in tandem to provide reliable delivery of data between applications running on host systems connected to a network. During an Internet transmission:
- IP breaks the sender’s data into small pieces called packets and relays the packets across the Internet based on the IP address in the packet header.
- TCP establishes a connection between the applications and ensures that the sender’s data is delivered, error-checked, and reassembled in the proper order on the receiving end.
