What is the Full Form of DHCP ?

DHCP - Dynamic Host Configuration Protocol

Dynamic Host Configuration Protocol is a network based protocol that assigns dynamic IP addresses to a computer, each time it connects to an IP network. DHCP protocol allows a computer to connect to an IP enabled network without a need to pre-configure it with specified IP address and other configuration information.

With dynamic IP address, it means, every time a system is connected to a network, a new IP address is assigned to it from the pool of available IP addresses.

To accomplish this, a DHCP protocol needs a server, known as a DHCP server. A DHCP server stores all the relevant information like a pool of IP addresses, subnet mask, network gateway and other relevant information that the system needs while connecting to a network.

Dynamic Host Configuration Protocol resides at the topmost layer ie. the application layer of the TCP/IP model.  The protocol also reduces the work of the system administrator, by allowing him not to configure IP addressing on any system.
