Network Switch Details and Price in Kenya

A network switch (also called switching hub, bridging hub, 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 the data link layer of the OSI model. Some switches can also forward data at the network layer by additionally incorporating routing functionality. Such switches are commonly known as layer-3 switches or multilayer switches.

FEATURES

It is an intelligent network device that can be conceived as a multiport network bridge.

It uses MAC addresses (addresses of medium access control sublayer) to send data packets to selected destination ports.

It uses packet switching technique to receive and forward data packets from the source to the destination device.

It is supports unicast (one-to-one), multicast (one-to-many) and broadcast (one-to-all) communications.

Transmission mode is full duplex, i.e. communication in the channel occurs in both the directions at the same time. Due to this, collisions do not occur.

Switches are active devices, equipped with network software and network management capabilities.

Switches can perform some error checking before forwarding data to the destined port.
