Kbps (Kilobits Per 
Second)

LAN (Local Area 
Network)

an office, single building, or group of buildings.

LED (Light Emitting 
Diode)

An electric component that emits light (turns ON) when current flows through it.

MAC (Media Access 
Control) address

A unique number that is assigned by manufacturers to each Ethernet network 

device. A MAC address lets a network identify Ethernet network devices at the 

hardware level.

Mbps (Megabits Per 
Second)

A measure of data transfer speed.

Megabits/Megabytes

One million bits/bytes.

Modem

A device that allows a computer to transmit data to other computers.

NAT (Network 
Address Translation)

An Internet standard that enables a LAN to use one set of IP addresses for internal 

traffic and a second set of IP addresses for external traffic. NAT provides a type of 

firewall security by hiding internal IP addresses. Since they are used internally, 

such IP addresses will not be in conflict with those used by other companies and 

organizations.
