Networking

1. LAN

   • Local area Network is when nodes in the network are connected over a small geographical location.
     • Shared through the internet, Nodes such as smart phones,printers,Computers
       • Hardware needed to connect are: Modem (to connect to the internet). Switch,Hub(Broadcasts data to all nodes)
         • ADVANTAGE: Share peripherals such as printers,therefore it is more cost effective. Easier to share files through the networks install programmes on everyone simultaneously insted of installing into eachone
           • DISADVANTAGE:A virus can spread more easily. If a virus gets into one computer it is likely to spread quickly across the network and damages all devices connected.

2. WAN

   • Wide area network is when the nodes in the network are shared after a large geographical location
     • Made up of several LANs connceted together,used in companies and businesses

3. Nodes

   • Pieces of software connected to a network
     • Computers,Smartphones,Printers,Tablets,Laptops

4. Star Topology

   • All the devices are connected to a central switch or server that controlls the network
     • The central switch allows many devices to access the sever simultaneously. Star networks may be wired or wireless

5. Peer-to-Peer Network

   • All devices are equal,connecting directly to each other without a server,

6. Client server

   • Managed by server,Clients are the nodes connected to the network.
     • Clients send requests to the server.The server processes the request and responds
