Computer Networks are sets of computers linked to each other to enable communication to share assets and material. They can be joined using optical fibers, Ethernet, wireless LAN, to name a some options. Wireless technologies encompass microwaves, satellites, radio or cellular technology, Bluetooth, etc.

Wired technology uses twisted-pair wire, coaxial cables or fiber optics. Twisted-pair wires and optical fiber cables are positioned in buildings to enable local area networks |LANs}.These cables are arranged in position by towing them along a route which could cause them to turn as well as make it tough to tow many at a time. It could wreck the wires; hence a cable puller can be used by operators which can tow a group of wires simultaneously with same force applied to each on a given route. Cable pullers which are dependable, lightweight touse, enable these to be towed whilekeeping the exact amount of pull so the wires aren’t affected in the process. You can locate a list of them here http://www.cablepuller.org.

Networks are classified based on the area they cover, usage, and access rights. So we can have local area networks (LAN) which are confined to a building to larger usage space networks like wide area networks (WAN) to metropolitan area networks (MAN), personal area networks (PAN), these being the more general ones.

PAN is used for communications between personal computers, printers, telephones and can include wired or wireless associations. LAN covers a house, office or small cluster of buildings like a institution. It can also be wired or wireless. A MAN connects local areas and usually doesn’t stretch beyond a city. A WAN covers national boundaries; hence it spans a wider area.

The Intranet can be accessed only by valid users within a organization. It is the internal network of an organization. An extranet is likethe intranet except that it has associations to few other trusted entities not in the company like other users. The Internet is the World Wide Web joining all available organizations be it academic, government, public networks, etc.

The basic building blocks of networks to link each node in it are Network interface cards, bridges, hubs, switches and|or routers. A network interface card is a hardware device that allows computers to interact over a network by providing physical access and an addressing scheme using MAC addresses. Repeaters obtain signals which it transmits at a higher level so it can travel longer spans while maintaining quality. Hubs consist of a number of ports and are used to send packets which appear at each, especially for broadcasting. Bridges join a number of networks and joins ports to an address and hence sends data to that particular port for which address it is sent. Switches normally have multiple ports and filters and forwards data between ports based on the MAC packet addresses Routers decide the next best path to transmit packets between networks.

The topic on networking is huge, we hope you liked this summary and have a basic idea of what goes into linking us all jointly via the net.
