13.4.1 Introduction to a Network connection
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 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.
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.
MAC address
Media Access Control address. Unique hardware number, used in combination with the IP-address to connect to the
network (LAN or WAN).
