Network

1. LAN

   • A LAN is a local area Network - a Network based in a small location or single organisations.
     • Advantage for LAN: an advantage its very cheap and you can access the same files on different computers.
       • Disadvantages
         • poor scalability, investment in higher costs due to server systems

2. WAN

   • A WAN is a wide area Network - a Network over a large area or multiple organisations
     • Advantage for WAN: wan is much bigger then LAN
       • Disadvantages
         • The disadvantage for a WAN network is that its very expensive!

3. IP address

   • An IP address is a unique value assignment to energy computer on a network, used to identify it.

4. Mesh Topology

   • The internet is a giant mesh of computes. There are multiple different routes between any two nodes.
   • in a mesh topology, there is a excellent resilience to outages as messages can take many different routes to reach a destination.

5. A Network is a collection of connected computers.

6. Disadvantages for a Network: they are very expensive and increased risk of viruses.

7. A Network Topology is the arrangement of computers and other elements of a Network.

   • Bus Topology
     • Advantages
       • Cheap to install.
     • Disadvantages
       • High risk of catastrophic failure, lots of collision, slows down as more computers are added.
   • Ring Topology
     • Advantages
       • Cheap to install, its fast.
     • Disadvantages
       • High chance of catastrophic failure, difficult to expand.
   • Star Topology
     • Advantages
       • Low chance of failure, its fast.
     • Disadvantages
       • Expensive, depends on a switch.

8. The advantages for having your computers on a network is the manager of the business can see if everyone is working and doing a good job. You can access your work on any computer on the network even if you saved it on another computer.
