Networks!

1. Bus Network Topology

   • Advanatages
     • Simple type of network
     • Cheap
     • If computer fails the network will still work
   • Disdavantages
     • If the main computer cable breakdown computers wont work
     • Speed of network is slow.

2. Networks

   • Advantages
     • Hardware (peripheral devices) can be shared. For example, a printer on a network can be shared. Network computers can communicate.
     • Software can be shared. Computer programme can be installed on one computer then shared to others.
     • Data can be shared. Stored on a network can be accessed by any computer
     • Can back up and be stored on computer.
   • Disdavantages
     • The cost of cabling and setting up can be high.
     • Viruses can be spread through a network very quickly.
     • Hackers can gain access to the network
     • Networks can fail to work properly.

3. Star Network Topology

   • Advantages
     • If one computer or cable breaks it doesn’t affect the rest of computers.
     • Access to file server is faster.
   • Disadvantages
     • Expensive to install
     • Connected to a central hub directs flor of data to central computer.

4. Ring tropology

   • Advantages
     • Inexpensive – cheapest network to set up
     • Data speed is continuous(no data collision)
   • Disadvantages
     • If one cable breaks down the whole network is affected.

5. LAN

   • A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, or office building.

6. WAN

   • A wide area network (WAN) is a telecommunications network or computer network that extends over a large geographical distance.
