A network switch connects devices within a network and forwards data packets to and from them. Learn the difference between switch and router, layer 2 and layer 3 switches, and how to protect network 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.
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. A network switch is a multiport network bridge that uses MAC addresses to forward data at ...
A switch is a hardware component in network infrastructure that performs the switching process. The switch connects network devices, such as computers and servers, to one another. A switch enables multiple devices to share a network while preventing each device's traffic from interfering with other devices' traffic.
