Cables:Cable is the medium through which information usually moves from one network device to another.
Copper Cables: copper cable is a group of two or more copper wires bundled together in a single sheath or jacket. Copper wire and cable is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment.
Fiber Cables: Fiber optic cables are used for lighting and imaging and as sensors to measure and monitor a vast array of variables. Fiber optic cables are also used in research and development and testing across all the above mentioned industries.
Hubs: A hub, also called a network hub, is a common connection point for devices in a network. Hubs are devices commonly used to connect segments of a LAN. The hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
Switches: A network switch is a multiport network bridge that uses hardware addresses to process and forward data at the data link layer (layer 2) of the OSI model. Some switches can also process data at the network layer (layer 3) by additionally incorporating routing functionality.
