Network

Network

1. Advantages

   • You can access your files from different computers.
   • You can share stuff with other people.

2. disadvantages

   • You can get hacked.
   • Things can go wrong easily.
   • It can take a long time to download.
     • This is because of data collisions

3. Lan/Wan

   • Lan
     • Local area network.
   • Wan
     • Wide area network

4. bus topologies

   • advantages
     • It is cheap and easy to set up.
   • disadvantages
     • It can take a long time to deliver something due to data collisions. If the wire is broken the network is broken.
   • All the computers are connected to a single cable.

5. Ring topoiogles

   • advantages
     • It is cheap easy to set up.
   • disadvantages
     • Catostrophic falure could occur and if one computer stops working the whole network stops.
   • All the computers are connected in a ring.

6. star topologies

   • advantages
     • There are no data collsions it is easy to exspand and it is very fast.
   • disadvantages
     • catostrophic falure occurs and it is very expensive
   • All the computers are connected to a central switch.

7. IP Addresses

   • An IP address is unique value assigned to every computer on a network used to identify it.
   • Messages on a network have an IP address attached which is how a computer Knows whether or not to keep the message.
   • Conflict is a problem with IP addresses as this occurs when two or more devices on the same network are assigned the same IP address.
     • To overcome this I would convert the network to a different device.

8. Mesh Topology

   • A mesh topology has no central connection point. Instead each node is connected to at least one other node.
   • Disadvantages
     • It costs a lot and it takes a long time to install things also all the nodes need to be active at the same time
   • Advantages
     • It can manage high amount of traffic easily, a failure of one device does not effect the whole network and adding additional devices does not disrupt data transmission.

9. We do network to allow us to go online and access files and whatever you need or want to see.
