Dynamic Host Configuration Protocol (DHCP) allows someone's computer to ask the network for an Internet Protocol (IP) Address. The computer then makes use of the IP Address in order to browse the Internet or check a person's e-mail. The purpose of using DHCP is to avoid having to manually assign a specific IP address to every user's computer. In this situation, for example, if one person uses a computer with a specific IP address and another person tries to use another computer that has the same IP address, the second person will be unable to do anything until the first user has turned his computer off.  Using DHCP eliminates these problems.
