Understanding network protocols

A network protocol is a collection of rules and data formats that define intercommunication between applications. For example, a web browser and server communicate via HTTP. HTTP is more like a set of rules than a transport protocol. Transport protocols are at the base of every network communication. An example of a transport protocol would be TCP. When we mentioned the TCP/IP suite, we meant the implementation of TCP over IP. We can consider the IP protocol as the heart of internet communications.

It provides host-to-host routing and addressing. Everything we send or receive online is packaged as an IP packet. The following diagram shows what an IPv4 packet looks like. In this context, an octet refers to a group of 8 bits equivalent to 1 byte:

The IP header weighs 20 bytes. It combines necessary flags and options for delivering a packet from the source address to the destination address...
