How do you read TCP IP?


TCP/IP Basics

When you use TCP/IP, you are using a network of computers to communicate with other users, share data, and share processing resources. A computer network is a group of nodes connected by a communication medium.

Difference between TCP/IP and OSI Model

  • OSI refers to Open Systems Interconnection
  • TCP/IP refers to Transmission Control Protocol
  • OSI follows a vertical approach
  • TCP/IP follows a horizontal approach
  • OSI model, the transport layer, is only connection-oriented
  • The TCP/IP model is both connection-oriented and connectionless

IPv4 Address

  • An IPv4 address is a 32-bit address that uniquely defines a device’s connection to the Internet.

Reason for Inventing TCP/IP

  • The TCP/IP protocol suite was created in the 1970s by DARPA scientists Vint Cerf and Bob Kahn to explore alternative network designs and assist network research.

Analogous Layers in TCP/IP

  • Host-to-Host Layer is analogous to the transport layer of the OSI model.
  • The transport layer links the network support layers (physical, data link, and network) and user support layers (session, presentation, and application) by segmenting and rearranging the data.
