5.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
LAN
A Local Area Network, or a shared communication system to which many computers are
attached. A LAN, as its name implies, is limited to a local area such as a home or office
environment. LANs have different topologies, the most common being the linear bus and the
star configuration.
IP Address
IP addresses identify individual devices on a network. Every networking device (including
computers, servers, routers, printers, etc.) needs an IP address to communicate across the
network. These networking devices are also known as hosts.
Subnet Mask
The subnet mask specifies the network number portion of an IP address. Your device will
compute the subnet mask automatically based on the IP Address that you entered. You do not
need to change the computer subnet mask unless you are instructed to do so.
Daytime
A network protocol used by devices for debugging and time measurement. A computer can
use this protocol to set its internal clock but only if it knows in which order the year, month,
and day are returned by the server. Not all servers use the same format.
