42.Explain TCP/IP networking.
Ans.
1. TCP/IP is transmission control protocol and belongs to the family of protocols used for computer communication.
2. TCP and IP are two different protocols from the group of protocols called as TCP/IP protocol suite.
3. TCP/IP protocols suite also includes address resolution protocol (ARP);Domain Name System (DNS);Internet Control message protocol(ICMP);User Datagram Protocol(UDP);Routing Information Protocol(RIP);Simple Mail Transfer Protocol(SMTP);Telnet and many others.
4. Each device connected to a network must have an address to communicate called as Device address.
5. Device address has two parts: the address of the network to which the device is connected and the address of device itself, i.e. host address.
6. These two unique addresses are called as network layer addresses and the media access control (MAC).
7. Network layer addresses are IP addresses that have been assigned to the device whereas Mac addresses are built into the Ethernet card by the manufacturer.
8. Data is transferred by breaking information into small piece of data called packets or Datagrams
9. Transferring data in packets avoids error in communication.
