Networks

Networks

1. Advantages

   • consistent use
   • shared logins

2. LAN

3. disadvantages

   • expensive
   • error
   • difficult
   • less creative

4. Bus

   • disadvantages
     • high chance of catastrophic failure
     • high chance of collisions
     • big networks are slower
   • advantages
     • cheap to install
     • only requires one cable

5. Ring

   • Advantages
     • cheap to install
     • no collisions
   • disadvantages
     • High chance of catastrophic failure (if any cable breaks or any computer goes down, the entire network fails
     • Difficult to add new computers

6. Star

   • Advantages
     • Fast (low chance of collisions)
     • Easy to add new computers
     • Low chance of catastrophic failure (a broken cable only takes out one computer, the rest of the network is fine)
   • Disadvantages
     • Expensive (needs a lot of cabling, and a central switch, which is expensive)
     • Failure of the switch will take down the network

7. IP address

   • Computers on a network also need an address to identify them
   • When a computer is added to a network it is assigned an IP Address (Internet Protocol Address
   • The IP Address is unique value assigned to each computer on a network
   • Each IP address on a network must be unique
