Assigning a hostname to a PC or HOST is just like giving a name to an IP.
HOST means all the computers in a network.Each computer is a host in a network and the ip address assigned to that host machine or that computer is host address and the name given to that particular pc or computer or host is hostname.
IP assigned to the host pc or any pc in a network is known as host address and the name assigned to any pc or host in a network is known as hostname.
see it's not easy for anyone to remember ip address so we need a name for each ip in our local network to differentiate or to identify specific machine easily and to make our task easy.

IP assigned to the host pc or any pc in a network is known as host address and the name assigned to any pc or host in a network is known as hostname.
