Try to imagine if this whole write up appears as one really really long sentence.
"Trytoimagineifthiswholewriteupappearsasonereallyreallylongse ntence". You would find it hard to read and understand. A conversation between two people is usually made up of many smaller sentences instead of having one really long sentence.Smaller sentences make it easier for the message to be received with understanding. These smaller sentences have a limitation of size. The processing ability of the other person (amount of information the other person can process per time) might also be a limitation. In the same wise, when a long message is sent from one host and received at another over a network, it will only make meaning if the message is broken into smaller pieces. This process is known as segmenting. Each segment is encapsulated in a separate frame which has the address information before being sent over the network.There are rigid rules which govern this process as frames which are either too long or too short will not be delivered. It must meet the minimum and maximum size specification. These rules can be different depending on the media through which the message is sent. On arrival at the destination host, the message is de-encapsulated and then reconstructed back into the original message so as to be processed and interpreted.
