three. Transport layer
four. Application layer
Community interface layer
The bottom layer with the TCP/IP design. Its process is to supply access to the transmission Actual physical medium and it differs based on the implementation from the medium.
Network layer
The network layer gives community addressing, routing and datagram transmission. Utilized protocols which will be of desire additional pertaining to DHCP are IP and ARP.
IP protocol
It really is The fundamental protocol of the network layer and usually the internet in general. It sends http://www.bbc.co.uk/search?q=해외스포츠중계 datagrams, that happen to be independent units that incorporate information regarding the destination, supply as well as sequence amount of the datagram.

Software layer
The applying layer is made up of plans that use net companies to fulfill the requires of customers. Examples of specific protocols are As an example FTP, DNS and DHCP.
Application protocols use TCP, UDP or both expert services simultaneously.

It is possible to alter the ports from the options on the company, but Each website individual services has a default port that isn’t improved for most expert services and is also employed as an unwritten typical.
” FTP = 21
” DNS = fifty three
” DHCP = sixty seven sixty eight
