Networks Hardware – Network Media Coaxial Cable(COAX) Coaxial Cable (COAX): It's a fairly common type of shielded data transmission cable, which is made up of two conductors that are coaxially oriented but separated by a layer of insulation. Data transfer speed has a rate between (10 to 100 Mbps), Maximum cable length 500 meters.

Networks Hardware – Network Media Twisted-Pair Cable: Twisted-pair cables can be either STP (shielded twisted pair) and UTP (unshielded twisted pair), data transfer speed has a rate between (10 to 1000 Mb / s), and maximum cable length 100 meters.

Networks Hardware – Network Media Fiber-Optic Caple Fiber-Optic Cable: is made up of 100 or more incredibly thin strands of glass or plastic known as optical fibers. each of which is capable of transmitting messages modulated onto light waves. data transfer speed has a rate between (100 Mb/s to 1 Gb/s), and is used to data transfer for very long distances.

Networks Hardware – Network Media WIRELESS NETWORKS Wireless: In some types of networks may not prefer or cannot extend the cables and thus media can be used for wireless sending and receiving data. • Radio Frequency (RF) like Wi-Fi, 3 G, 4 G and Bluetooth • Microwave • Satellite • Infrared

Networks Hardware Network Interface Card (NIC): 3 - Network Interface Card (NIC): is the hardware device that enables you to send and receive data to and from your computer. An adapter can connect to the network by cable (wired) or by air (wireless)

Networks Hardware – Connectivity Devices: Are devices that work on connecting peripheral devices using common media of data transfer in order to transfer data between these devices as well as other functions related to improving network performance

Networks Hardware – Connectivity Devices 1. Hub Central connecting device Is the network will be fast? ?

Networks Hardware – Connectivity Devices 2. Switch: Switches work the same was as a hub, but they can identify the intended recipient of the data. Switches can send and receive data at the same time. Modified hub Faster in data transfer

Networks Hardware – Connectivity Devices Router Connect between two networks
