LAN: Local Area Network. A LAN is a small network, which accesses a WAN through a
Gateway. In most cases, the LAN is the network of computers in your home, which access
the internet (WAN) through a router configured as a Gateway.
MAC: Media Access Control. A MAC address is a unique identifier assigned to network
interface devices. Each Network Interface Card (NIC), for example, has a unique MAC
address. While a computer's IP address may change frequently, its MAC address will
remain the same, unless it undergoes a physical change in hardware.
DNS: Domain Name System. The DNS is a system of alphanumeric names to identify
locations on the internet, rather than forcing users to use the raw IP address. Since an IP
can change, the DNS system allows users to continue to access a particular domain, even
if its IP has changed.
Channel: Because many wireless devices use the same frequency a system of channels is
used to separate the different transmissions, thereby eliminating interference and crosstalk.
This is the same functional concept as the use of channels on a TV to separate the different
transmissions coming in over the single RF cable.
SSID: SSID (Service Set Identifier) is the network name shared by all devices in a wireless
network. Your network's SSID should be unique to your network and all devices within the
network must use the same SSID. It is case-sensitive and limited to a maximum of 20
characters. You may use any of the characters on the keyboard.
DHCP: Dynamic Host Configuration Protocol. The DHCP is a system for configuring
computers connected to IP networks. It eliminates much of the manual work that would
have to be done by a network administrator. It also maintains a central database of all the
devices connected to a network and eliminates duplicate resource assignments.
