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.
Layers of TCP/IP
- Network Layer
- Internet Layer
- Transport Layer
- Application Layer
Protocols Working in TCP/IP Model
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
