Category:
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.
