Community layer

The community layer delivers community addressing, routing and datagram transmission. Made use of protocols which will be of desire even further about DHCP are IP and ARP.

IP protocol

It truly is The fundamental protocol of the community layer and usually the net as a whole. It sends datagrams, which are impartial units that consist of details about the desired destination, source and the sequence amount of the datagram.

Application protocols use TCP, UDP or the two services simultaneously. So referred to as ports are utilized to differentiate concerning application protocols, they stand for a kind of label of the application. It is possible to alter the ports inside the options in the service, but Every service has a default port that isn’t changed for many solutions and it is made use of as an unwritten typical.

” FTP = 21

” DNS = 53
