Switches are a bridge between the internet networking device and computing device. A switch is connected with the router to receive and responds to request operations. Multiple computers can be connected through switches. Switches are used at the networking Level devices. Not only computing devices but also printers and other devices are connected with a switch. It sends and receives data packets from another networking device like routers. For receiving data packets it uses MAC address in order to select destination port address. Computer devices, printers, Xerox machines, and other devices can be connected with each other through switches. It identifies each device through its MAC address. A switch operates in the 2nd layer of the OSI Model. The datalink layer is the second layer of the OSI Model. It uses different modes of communications like unicast (one-to-one), multi-cast (one-to-many), and broadcast (one-to-all). Switches are used in Complex network architecture to facilitate proper network operations.

Switches are one of the important components of networking devices. A switch is externally connected with routers or other switches, and internally it is connected with a computer device, printers, and switches itself also. There are many types of switches available. They are categorized used according to their need.
1) UnManaged Switch
It is a very special type of switch specially designed for small usage. It is designed in order to use at small offices and at the home networks. It is simply plugged into the other devices in order to operate it. There is no need of configuring Un Managed Switches.
2) Managed Switch
It is the advanced level of switch used in the networking module. It is expensive as compared to an unmanaged switch. It is used in big corporates. It is also used in complex network architecture. It is mostly demanded in the corporate world due to its simple configuration method and usage. It is durable and long-lasting. In the configuration process of a managed switch, SNMP (Simple network management protocol) is used.
3) LAN Switch
LAN Switches are used in a particular area. We can say that these switches are used in the local area networks. These switches are used to reduce the network congestion over the network. It is also referred data switches and ethernet switches. It is designed in such a manner that there is no delay or missing of data in data packets.

4) PoE Switch
It stands for Power Over Ethernet Switch. It is used for dual-use. Data and current both are passed at the same time. So it is used for data as well as for electric current. It is durable and simpler. The overall connectivity of the cable wire becomes simple.
