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
