A network switch connects devices within a network and forwards data packets to and from them. Learn the difference between layer 2 and layer 3 switches, unmanaged and managed switches, and how to protect switches from DDoS attacks.
A network switch connects devices in a network to each other, enabling them to talk by exchanging data packets. Switches can be hardware devices that manage physical networks or software-based virtual devices. A network switch operates on the data-link layer, or Layer 2, of the Open Systems Interconnection ( OSI) model.
Switching in IT and computer networking is the transfer of data packets, or blocks of data, through a network switch. Switches transfer data from source ports on devices such as computers to destination ports on devices such as routers. See network switches.
A network switch (also called switching hub, bridging hub, Ethernet switch, and, by the IEEE, MAC bridge) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.
Jul 28, 2022 · A network switch connects and transmits data packets to and from devices on a local area network (LAN). Far from a router, a switch only distributes information to the one device for which it was designed, including some other switch, a router, or a user’s computer, rather than to several devices in a network.
