D-Link DGS-2205 Ethernet Desktop Switch - DGS 2205 

A network switch is a computer networking device that connects network segments.

 Ethernet implementations of network switches support either 10/100 Mbit/s or 10/100/1000 Mbit/s ports Ethernet standards. Large switches may have 10 Gbit/s ports. Switches differ from hubs in that they can have ports of different speed.

A switch is something that is used to turn on or off various electronic devices. However, in computer networking, a switch is used to connect multiple computers with each other. Since it is an external device it becomes part of the hardware peripherals used in the operation of a computer system. This connection is done within an existing Local Area network (LAN) only and is identical to an Ethernet hub in terms of appearance except with more intelligence.

An Ethernet switchcan be thought of as a device that makes temporary crossover cable connections between computers that want to communicate. Just like crossover cables, switches do not suffer from the problem of collisions.

Switches may operate at one or more OSI layers, includingphysical, data link, network, or transport (i.e., end-to-end). A device that operates simultaneously at more than one of these layers is called amultilayer switch. switches not only receive data packets, but also have the ability to inspect them before passing them on to the next computer. That is, they can figure out the source, the contents of the data, and identify the destination as well.
