networks

1. disandvantagies

   • High chance of catastrophic failure (if any cable breaks or any computer goes down, the entire network fails Difficult to add new computers

2. addvantagies

   • Cheap to install (one cable per computer) No collisions - only one computer is transmitting on each cable

3. Types of network

   • WAN
     • a network over a large area or multiple organisations
   • LAN
     • Local area network

4. networks toplogies

   • bus
     • addvantagies
       • Cheap to install (only one wire needed)
     • disandvantagies
       • High chance of catastrophic failure (a break in the central cable takes out the entire network) High chance of collisions (multiple communications on the same cable that corrupt each other, slowing down the network) More computers mean more collisions, so the network gets slower as it gets bigger
   • RING
     • ADDVANTAGIES
       • Cheap to install (one cable per computer) No collisions - only one computer is transmitting on each cable
     • Disandvantagies
       • High chance of catastrophic failure (if any cable breaks or any computer goes down, the entire network fails Difficult to add new computers
   • star
     • A Star topology is all computer connected to a central switch

5. ip adress

   • 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
