Category of cellular transmission that transmits digital data at speeds from 9.6 Kbps to 144 Kbps.

Mobile computers and devices, such as a mouse, printer, and smartphone, often have this kind of port to enable the transfer of data from one device to another using light waves.

The core of this kind of cable consists of dozens or hundreds of thin strands of glass or plastic that use light to transmit signals.

Transmission media that uses wire, cable, and other tangible materials to send communications signals.

Contactless payment uses this technology.

A form of broadcast radio that is used widely for mobile communications.

This kind of device contains a small chip that allows it to communicate with other similar devices.

Kind of network that is sometimes called a file sharing network.

Category of cellular transmission that transmits digital data at speeds up to 100 Mbps.

A wireless transmission medium that distributes radio signals through the air over long distances.

Can be negatively affected by the distance between two points, the type of transmission media, and the number of nodes through which data must travel.

To prevent unauthorized users from accessing files and computers, many routers are protected by these.

Standard that specifies how wireless devices communicate over the air in a wide area.

Consists of a single copper wire surrounded by at least three layers.

Transmission media that sends communications signals through the air or space using radio, microwave, and infrared signals.

Examples of standards in this category include EDGE and UMTS.

Type of lines that can be either analog or digital.

Kind of cable designed to reduce noise.

Protocol that defines how a network uses radio signals to communicate with a tag placed in or attached to an object, an animal, or a person.

A network standard that specifies how two devices use short-range radio waves to communicate at high speeds with each other.
