Wide Area Network. Computer networks that encompass a wide geographical area and connect LANs, CANs, and MANs together.

Specialized wire that cancels out electromagnetic interference from other electronic devices and increases reliability.

The mapping of a physical network and logical interconnections between nodes.

Transmission Control Protocol / Internet Protocol, the most common network protocol that breaks large files into packets and guarantees the reliability of the computer file received by the network's end user.

A password that contains a specific amount of characters with mixed cases and often requires letters and numbers.

The star-shape created by network nodes that radiate around a central node in a spoke-like fashion.

A standard language that exists in order for the connected computers to communicate.

restricting or granting of access to specific files and folders on a computer network to a user or group of users.

A secret word or combination of keyboard characters typed in by a users to authenticate their identities to a computer network.

A memorable strong password.

Peer-to-Peer Network. Computer networks that generally connect computers directly to one another without the use of a server.

Any and every device connected to a network.

The person(s) responsible for smooth network operations, network performance and implementation of new nodes, or even new networks.

Network Operating System, software that controls an entire network.

Network Interface Controller Card, a computer card plugged into a slot on the motherboard inside of the computer and allows a network cable to be plugged in so it can interface or communicate with other computers.

Metropolitan Area Network. A computer network that connects two or more LANs or CANs together but within the boundaries of a town or city.

Local Area Network. A computer network that is relatively small, typically in a single building, but sometimes as small as a single room.

A private version of the Internet that works the same way, but it is confined within an organization.

A central location of the computer network that serves as a traffic cop for network connection and communication.

Specialized hardware and software that ensures that only authorized personnel can access and use an organization's Intranet.

Two or more computers connected together to communicate and share resources.

Campus Area Network. A computer network that connects two or more LANs that are located on a campus.

A network topology sometimes called a linear bus, where each of a network's nodes is connected to a common linear backbone that has two endpoints.
