Networks

Networks

1. Types of Network

   • LAN
     • Local Area Network
   • WAN
     • Wide Area Network
   • WLAN
     • Wireless Local Area Network
   • PAN
     • Personal Area Network
   • Client server
   • Peer-To-Peer

2. Topologies

   • topology is how the network is set up.
   • Bus Topology
     • Easy to set up, Cheap
     • Problems with the backbone will bring the while network down, limited distance can be covered, many data collisions slows the network down
   • Star Topology
     • Robust- Problems dont affect the network, fewer data collisions than bus so its faster
     • Needs more expertise to maintain, can be expensive to set up theres more network hardware + software needed
   • Ring Topology
     • Very Fast - No collisions
     • Probelms with the backbone can bring the whoile network down, Data passes through every node - makes the network more vulnerable to malfunctions
