Network types

Network types

1. LAN

   • Local access network
     • Computers all join together to form a securer network.
   • It is very secure as it's all connected by a wire so it's harder to intercept.

2. WAN

   • Wide access network
     • All connected together through multiple LANS.
       • It is very secure because of it.
     • Used to cover wider areas like towns etc.

3. Client server

   • When a client makes a service request to use a server from places like google.
     • Prone to DDOS attacks as it could easily receive too many service requests.

4. Peer to Peer

   • Peers connected together to share files.
     • Can be used to make sharing downloads faster.
       • It is also used in businesses to organise stuff like how many tickets are bought and how many are left.

5. Topologies

   • Star
     • Connected from a router
     • If one device crashes it will still run so it is good.
       • However if the central hub or router breaks all the devices will stop working.
   • Mesh
     • All computers connected by cables.
     • Good because if one cable breaks the other computers can still communicate.
       • It is expensive because all the computers have to the wired together
   • Bus
     • All connected together through a central cable.
     • It is cheap and easy to set up
       • It will stop working if the central cable breaks
   • Ring
     • All connected together and has to go through all of the computers.
       • Can be slow because of it.
       • Easily set up and cheap.
