* Application Layer- is the highest layer of the Internet protocol suite commonly known as the internet user protocol which provides direct service to users such as the Telnet (remote login), [[FTP]] (file transfer) and [[SMTP]]   (electronic mail delivery).

* Transport Layers- provides a reliable end-to-end communication or data transfer for applications. TCP and UDP (User Datagram Protocol) are the main transport layers.

* Internet Layer- The Internet Protocol is the most important component of the layer which provides the addressing or the routing of a sent data to its destination.

* [[Internet Layer]]- The Internet Protocol is the most important component of the layer which provides the addressing or the routing of a sent data to its destination.

* Link Layer- also known as the media access protocol layer provides interface to an actual networking hardware such as the ethernet or gateways.
