A network switch connects devices within a network (often a local area network, or LAN *) and forwards data packets to and from those devices. Unlike a router, a switch only sends data to the single device it is intended for (which may be another switch, a router, or a user's computer), not to networks of multiple devices.
An Ethernet switch is a type of network hardware that is foundational to networking and the internet. Ethernet switches connect cabled devices, like computers, Wi-Fi access points, PoE lighting and IoT devices, and servers, in an Ethernet LAN so they can communicate with each other and to the internet.

A network switch is a technology that allows two or more IT devices such as computers to communicate with each other, forming a communications network. Switches enable devices on the network to share IT resources such as printers, servers, file storage, internet access, and processing. Simple switches connect devices on a single local area ...
Jul 21, 2023 · A network switch is a small box that adds extra Ethernet ports to your router. If you want to use several devices over a wired internet connection, or if you plan to install Ethernet ports in the walls of your home, you will need a network switch. Note that expensive "managed" switches, which are intended for business and industrial settings ...

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 devices, like computers, printers, and routers, to share ...
May 22, 2018 · A network switch—not to be confused with a light switch or a Nintendo Switch —is a box that you connect to your home router to gain more Ethernet ports. Think of it as functioning like a USB ...

Jul 26, 2022 · A network switch appears as a node in network topology and works with other devices, such as routers and firewalls to create complete networks. Network switches use Layer 2 of the OSI model and work at the data link layer (Layer 2). Switches operate at this level because this is where frames are used to identify each frame with its MAC address.
