§ Share Resources from one computer to another
§ Create files and store them in one computer, access those files from the other computer(s) connected over the network
§ Connect a printer, scanner, or a fax machine to one computer within the network and let other computers of the network use the machines available over network.
Following is the list of hardware’s required to setup a computer network.
§ Network Cables
§ Internal Network Cards
§ External Network Cards
§ Networking cables are networking hardware used to connect one network device to other network devices or to connect two or more computers to share printer, scanner etc.
§ Network Cable is the medium through which information usually moves from one network device to another.
§ A computer can be connected to another one via a serial port but if we need to connect many computers to produce a network, this serial connection will not work.
§ The solution is to use a central body to which other computers, printers, scanners etc. can be connected and then this body will manage or distribute network traffic.
§ A router is a type of device which acts as the central point among computers and other devices that are part of a network.
§ A router is equipped with holes called ports and computers and other devices are connected to a router using network cables. Now-a-days router comes in wireless modes using which computers can be connected without any physical cable.
§ Network card is a necessary component of a computer without which a computer cannot be connected over a network.
§ It is also known as network adapter or Network Interface Card (NIC).
§ Most branded computers have network card pre-installed.
§ Network cards are of two types:
· Internal Network Cards
· External Network Cards
Internal Network Cards:
§ Motherboard has a slot for internal network card where it is to be inserted.
§ Internal network cards are of two types in which first type uses Peripheral Component
§ Interconnect (PCI) connection while the second type uses Industry Standard Architecture (ISA).
§ Network cables are required to provide network access.
External Network Cards:
§ External network cards come in two flavours: Wireless and USB based.
§ Wireless network card need to be inserted into the motherboard but no network cable is required to connect to network.
§ USB card are easy to use and connect via USB port. Computers automatically detect USB card and can install the drivers required to support the USB network card automatically.
