Domain name System (DNS)
DNS stands fro Domain name system resolves hostname from IP addresses a look up on the DNS table will be performed which will retrieve the IP address otherwise it would have very for human beings to remember IP addresses but hostname are easy to remember.
www.google.com (its is a domain name) is much easier to remember than an IP address 64. 233.167.99, so all of them kindly remember the different in IP and domain name.
What Is DHCP?
DHCP stands for dynamic host configuration protocol .DHCP server dynamically assign Ip addresses (with the help of IP address one computer communicate with other computer) to clients (hosts) rather than network administration provide IP address to client statically . So it makes the administration purposes simpler.
