It has multiple ports and connects multiple devices, such as computers, laptops, wireless access points, printers, cameras and servers; on the same LAN within a building or campus. A switch enables connected devices to share information and talk to each other. It is called layer 2 device because it works on layer 2 of the OSI model and it uses mac address in order to share data from one end to other end. It learns the physical address of the devices that are connected to it and store the physical address called mac address in its mac table. Unlike hub switch is an intelligent device Switches are ASIC based .ASIC stands for application specific integrated circuit. This feature helps the switch to make the switching decisions very quickly. Every port on a switch is in a different collision domain, i.e a switch is a collision domain separator All ports on a switch are by default in the same broadcast domain. A broadcast domain contains all devices that can reach each other at the data link layer (OSI layer 2) by using broadcast. There are two types of switches Unmanaged switches An unmanaged network switch is designed so that you can simply plug them in and they work, no configuration required. Unmanaged switches are typically for basic connectivity. You'll often see them used in home networks or wherever a few more ports are needed, such as at your desk, in a lab, or in a conference room. One of the example of unmanaged switches include cisco 100 series switches. Managed switches Managed switches can be configure to custom-fit your network. Managed switches give you greater security and more features . With the greater control, and flexibility you can better protect your network and improve the quality of service for those who access the network.
