Device which changes signals on a copper cable to signals that run on fiber, letting a company introduce fiber in the network without making other changes.

Devices which check how the network is running and ensure that it is running at its most efficient (optimum).

Device used to split a signal if the signal must be sent to two or more devices.

A network switch is a computer networking device that links network segments or network devices. The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. Switches that additionally process data at the network layer (layer 3) and above are often called layer-3 switches or multilayer switches. A network switch is made up of network switch components.

A network switch is a computer networking device that is used to connect many devices together on a computer network. A network switch module is a self-contained hardware or software component that interfaces between a network switch and other devices.

A switch is a device with which it is possible to connect computers into a (local area) network, provided your computers all have an appropriate networking device installed. Switches can be daisy chained to form larger networks and come in managed and unmanaged variaties. The unmanaged versions generally cannot filter data and will forward any data that is fed into them, so they are better suited for small networks. Switches are easy to set up (just plug in the network cables) and allow you to share printers, storage space and other network resources with your entire home or office network.
