Introduction on TCP

  • TCP/IP stands for ‘Transmission Control Protocol/Internet Protocol’ .
  • It is a communication protocol that allows the computer to share various resources across a computer network.
  • It handles the reliable delivery of messages across the network.
Introduction

Layers of TCP/IP

  • Network Layer
  • Internet Layer
  • Transport Layer
  • Application Layer
Layers

Protocols Working in TCP/IP Model

Protocols

HTTP, FTP, POP3, SMTP, TCP, UDP, IP, Ethernet, ARP, IP

Full Forms

  • HTTP: Hyper Text Transfer Protocol
  • POP: Post Office Protocol
  • SMTP: Simple Mail Transfer Protocol
  • UDP: User Datagram Protocol
  • IP: Internet Protocol
  • ICMP: Internet Control Message Protocol
  • ARP: Address Resolution Protocol

Functions of TCP Layers

Data Network Layer

  • It controls all hardware devices and media.
  • It provides the interconnection between different hosts and nodes in a network.

Internet Layer

  • It determines the best appropriate path through the networks.
  • Routing of data to next level is possible.

Transport Layer

  • It is responsible for the transmission of messages and communication across diverse computer networks.
  • It provides end to end data delivery.

Application Layer

It represents the data to the users.

It uses:

  • HTTP & FTP: Web based
  • POP3 & SMTP: Email
  • SSL & TLS: Security
  • SNMP: Network management
