10.1.1 Ethernet Connection
IP
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.
Default 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.
DHCP
Dynamic host configuration protocol. DHCP is a communications protocol that lets network
administrators manage centrally and automate the assignment of IP addresses in an organi-
zation’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 ad-
dress 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 ad-
ministrator 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.

2 ways can be used to assign an address:
