IP Address
Internet Protocol. The network layer of TCP/IP. Required for communication with the internet.
Subnet mask
A number that is used to identify a subnetwork so that IP addresses can be shared on a local area network.
Gateway
A router that serves as an entry point into and exit point out of a network. For example, a local network (LAN) may need a
gateway to connect it to a wide area network (WAN) or to the Internet.
HDCP
Dynamic host configuration protocol. DHCP is a communications protocol that lets network administrators manage centrally
and automate the assignment of IP addresses in an organization’s network. Using the Internet Protocol, each machine that
can connect to the Internet needs a unique IP address. When an organization sets up its computer users with a connection to
the Internet, an IP address must be assigned to each machine. Without DHCP, the IP address must be entered manually at
each computer and, if computers move to another location in another part of the network, a new IP address must be entered.
DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically sends a new
IP address when a computer is plugged into a different place in the network.
