Networks Networking is a link between computers with Machine tools and programs designed to work Networking and to allow sharing of each other and flow of information across the network In the form of electrical signals and are transferred packaged small bits of information at speeds Very large and must travel these packages with a high degree of accuracy until you reach the free errors to the desired goal,

Types of Networks  Local Area Network (LAN)  Wide Area Network (WAN)  Metropolitan Area Network (MAN)  Internetwork – connected networks

 There are two of the network The first is based on the principle of client / server And the second on the principle of peer - to-peer.

Client / Server  client / server called the central computer, which provides programs and data to others, a provider server, the so-called each of the computers that are connected to, the customer client.  Networks require the client / server network operating system such as Windows 2000 Server

Peer - to -Peer  Peer - to peer where the computers are all equal in terms of network function performed by the network in the sense that there is no specific computer with functions central Kalmsud. Related services in the networks of peer - to peer, with each other directly, so as to enable the exchange of information

What are the means of data transfer?  Are the wires and cables and techniques used in signal transmission and networking between the various devices in a specific network or several networks tied with each other

Types and means of transport networks  Twisted pair cable This type of wire in the Ethernet networks of the type Star. Not to exceed a distance of delivery of 100 meters. Benefit of reducing the noise schedule wires noise.

Twisted pair cable

Types and means of transport networks (cuont)  Coaxial cable Is used with Ethernet networks of the type of Bus.

Types and means of transport networks (cuont)  Fiber optic cable Consisting of small bottles and one to send and the other for reception. 1gbps you move data quickly.

Types and means of transport networks (cuont)  Wireless media Used with networks of hybrid. Space connectivity depends on the network card and the factors surrounding. To be the availability of wireless card in your computer wireless adapter card.
