In fiber-optic cable, the glass fiber at the center of the cable

How the signals travel electronically in a network. Also called the logical topology

A commonly used type of cabling consisting of twisted pairs of wires without shielding to protect the wires from EMI

A rating system that grades cables based on the highest frequency in megahertz (MHz) a cable can handle, which, in turn, helps network installers get the right cable for the network technology.

Any form of network topology that combines a physical topology with a signaling topology.

Transmits light rather than electricity, making it very attractive for both high-EMI areas and long-distance transmissions

Describes how cables and other pieces of hardware connect to each other in a network.

A type of cable that contains a central conductor wire surrounded by an insulating material, surround by a braided metal shield, which together effectively shield data transmissions from electromagnetic interference

A topology in which two computers connect directly together with no need for a central hub or box of any kind.

The organization that establishes and promotes standards, including networking standards

A network topology in which all computers connect to the network via a single cable that connects all of the computer in line

How cables physically connect networked components

The part of a fiber-optic cable that makes the light reflect down the fiber.

A mesh topology in which every computer connects directly to every other computer

A topology that connects all computers on the network with a central ring of cable.

A network topology in which every computer connects to every other computer via two or more routes, making this topology the most fault tolerant

A network topology that uses a physical star design, while the actual signals travel on a ring

Bayonet-style connectors used to connect coaxial cable to computers

A topology in which a single system acts as a common source through which all members of the network converse.

A problem unique to multimode fiber-optic cables that use LEDs as the light source for the signal

A network topology that uses a physical star design, while the actual signals travel on a bus.

A network topology in which the computers on the network connect to a central wiring point (usually called a hub)

A portion of a network in which all devices are directly connected to common physical-layer components, such as a hub or repeater.

A network topology in which at least two machines have redundant connections, but in which every machine doesn’t have to connect to every other machine.

Fiber-optic cable that uses LEDs as the light source for the signal
