Computer network consist of different devices such as router, hub, switch, gateway and others. Without these network devices data cannot be transmitted from one computer to another in a LAN or WAN network. These devices link up all the local and remote network segments with each other to make data communication from one segment to another. The two important devices of a big network are routers and switches. A computer network with good infrastructure with properly placed and configured network devices such as routers, switches etc. are helpful in reducing the overall operational cost, improve the performance, manageability and reliability.
LAN Devices
Hub
A hub is a networking device, which is used to connect the two segments of a wired network. In star topology, every computer is directly connected with the hub. In case of any fault in the hub, the data communication in the network computers stops. In an Ethernet-based network a hub is a central device that is used to connect all the computers with each other.
