 A group of interconnected computers and peripherals that is capable of sharing software and hardware resources be tween many users.  A group of interconnected computers and peripherals that is capable of sharing software and hardware resources be tween many users. Network

 Device that is capable of performing its own task, without the need of any other device or component. Standalone

 (local area network) is a group of interlinked computers which can communicate and share resources wirelessly. LAN

 A network that is able to communicate and allow devices such as telephone lines and satellites to work on a larger geographical area than LAN. WAN

 An individual or an organization utilizing the help of a professional(s) such as a lawyer. Clients

 It is a software program that is dedicated to do a specific type of service. Server

 A place where a few programs, files etc. are located on a computer’s server, but are also available to various systems on the client network. Client Server Network

 It is a network which can enable communication services between two individuals. Peer to Peer Network

 A few peripherals can be shared between all workstations, instead of individual computers.  Files and documents can be uploaded on the server, and can be accessed by any workstation.  The transfer of data is much simpler between all users.  Single application packages can be shared between all workstations.

 If one computer receives a virus or a serious fault, it is transferred to the other computers connected to the network.  Networks are difficult to set up and are required to be maintained by technicians.  A powerful/good LAN is compulsory at all times for the network to run.  The workstations are more prone to hacking due to more access points. LINK: networks.blurtit.com/q html networks.blurtit.com/q html 4 Disadvantages

 A cabled LAN is when a wire is connected to the computers in order for them to use the network.  The three types are; - Twisted pair cable: two individual wires twisted around each other to make one. - Optical fibre cable: made up of transparent material that carry beams of light. - Coaxial cable: transmission line for high frequency signals. Cabled LAN

 It is essential for all computers to have LAN interfaces in order for them to work in the network. The port has to be connected to the appropriate socket. LINK: network-requirements.html network-requirements.htmlhttp:// network-requirements.html LAN Interface

 It describes the arrangement of systems which are located on a computer network. LAN Topologies

 There are structures for this including; - Star: A central node connected to the rest and interlinking them together - Ring: Each node is connected to two other nodes exactly, forming the shape of a ring. - Line: Nodes arranged in a straight, only linking between the one in front and behind.
