In the context of networking, a switch is a device that connects devices together in a computer network, enabling them to communicate with each other by exchanging data packets. A switch operates at the data link layer of the OSI model. With a switch, it's possible for wired network device...
A network switch operates on the data-link layer, or Layer 2, of the Open Systems Interconnection (OSI) model. In a local area network (LAN) usingEthernet, a network switch determines where to send each incoming message frame by looking at the media access control (MAC) address. Switches ...
Are you confused about how does a switch work? This article will help you understand what a switch is and how it works. A switch is a networking device that connects devices on a computer network. It allows multiple devices to communicate with each other by forwarding packets of data to ...
A network switch is networking hardware that connects devices on a network by using packet switching to receive and intelligently forward data to the destination device.
In the early stage of networking, the emergence of the hub brought great convenience to people, and were widely used before the invention of the switch. In a sense, the hub is merely a primitive predecessor to the switch. Therefore, hubs were replaced by switches a long time ago. Meanwhile...

The switch's CAM table is stored in memory. If the switch is turned off, the table will disappear and the switch has to relearn the table when it is rebooted. Now, suppose the switch was just turned on and has not yet created its CAM table. It does not know which ports Computers A...
What is a Network Switch? Anetwork switchis a crucial device in computer networking that serves to connect multiple devices within alocal area network (LAN). It operates at the data link layer (Layer 2) of the OSI model and, in some cases, at the network layer (Layer 3). ...

A switch combines the functionality of a bridge and a hub. It segments networks and can interpret and filter packet data to send it directly to an attached network device. Switches use the network device's MAC address to determine the data package's destination. A switch operates in full-dup...
