Protocols

Application Protocol:

    Hypertext Transfer Protocol (HTTP)

Transport Protocol:

    Transmission Control Protocol(TCP)

Internetwork Protocol:

    (IP)

Network Access Protocols:

    Data-Link protocols take packets from IP and put in physical media (I.E. Ethernet)

Packet Switching

Packet switching is the process of transmitting data in small units called as packets. In packet switching, data that is to be transmitted is split into smaller units. A small header containing signalling/addressing information about the source and destination nodes is added to each such small data unit, to form packets. Each packet is then routed from the source to the destination by intermediate data exchange devices, using the signalling information present in each packet. Packet switching is the switching method used in data networks for computer communication.

TCP/IP Protocol Suite and Architecture

Just as Ethernet rules the roost when it comes to LAN technologies and IEEE 802.11 is the boss of the wireless LAN world, modern internetworking is dominated by the suite known as TCP/IP. Named for two key protocols of the many that comprise it, TCP/IP has been in continual development and use for about three decades. In that time, it has evolved from an experimental technology used to hook together a handful of research computers, to the powerhouse of the largest and most complex computer network in history: the global Internet, connecting together millions of networks and end devices.

Interaction of protocols

The application layer sends data to the Transport layer which breaks up the information into smaller packets and those smaller packets get an address from a sender to a receiver. This Packet then becomes a Datagram that gets sent over the Internet (or Media) to be sent.
