1. Network Interface Card

   • Every device on a network will need a Network Interface. This is usually in the form of a NIC (network interface card). The purpose of the NIC is to provide a connection to the network. It converts data from nodes (any device on the network) into a format that is compatible with the network (network protocol). Every NIC has a unique address hard-wired called the MAC address (Media Access Control). Every node can be identified by this address.

2. Hub

   • A hub is a hardware device that allows nodes to be linked together and exchange data. On a wired network they are linked by cables. Data is moved in the form of 'packets'. This is a small chunk that has the destination address included. A hub transmits packets to every node on the network.#
