What is TCP IP Internet Networking

What is TCP IP Internet Networking


TCP/IP, Transmission Control Protocol/Internet Protocol, is a suite of communications protocols used to interconnect network devices on the Internet. TCP/IP implements layers of protocol stacks, and each layer provides a well-defined network services to the upper layer protocol. TCP and IP are the two protocols used by TCP/IP, as well as the (higher) application, (lower) data link and (lower) physical layer protocols.

What is TCP/IP?

- TCP/IP is the communication protocol for communication between computers on the Internet.
- TCP/IP stands for Transmission Control Protocol / Internet Protocol.
- TCP/IP defines how electronic devices (like computers) should be connected to the Internet, and how data should be transmitted between them.

Inside TCP/IP

Inside the TCP/IP standard there are several protocols for handling data communication:
  • 1. TCP (Transmission Control Protocol) communication between applications
  • 2. UDP (User Datagram Protocol) simple communication between applications
  • 3. IP (Internet Protocol) communication between computers
  • 4. ICMP (Internet Control Message Protocol) for errors and statistics
  • 5. DHCP (Dynamic Host Configuration Protocol) for dynamic addressing
  •  

TCP/IP

- TCP/IP is TCP and IP working together.
- TCP takes care of the communication between your application software (i.e. your browser) and your network software.
 - IP takes care of the communication with other computers.
- TCP is responsible for breaking data down into IP packets before they are sent, and for assembling the packets when they arrive.
- IP is responsible for sending the packets to the correct destination.
