  1. CS 350 Chapter-1 Terms in Networks

  2. What’s a Network? • LAN

  3. Network Components • Workstations • Servers • Hosts

  4. Virtual LAN

  5. WAN

  6. VPN

  7. Network Architecture • Peer-to-Peer • Client/Server

  8. Physical Net. Topology • Bus Topology • Star Topology • Ring • Mesh • Point-to-Point • Point-to-MultiPoint • Hybrid Topology

  9. Bus Topology • Pros: • Easy to install • Not expensive • Not much cable required • Cons: • Hard to troubleshoot, change, move • A single cable failure – bus itself

  10. Star Topology • Pros: • Easy to add new stations • A single cable failure is not a big deal • Easy to troubleshoot • Cons: • Larger number of cables necessary • A single point failure

  11. Physical Net. Topology • Ring – hard to add new, single cable failure • Mesh – most fault tolerance • Point-to-Point • Point-to-Multipoint • Hybrid Topology – Internet as an example

  12. Choose Right Topology • Cost • Ease of installation • Ease of maintenance • Fault-tolerance requirement • Examples: • simple home network – wireless access point • A fast growing company – wired star • Godzilla-strength fault-tolerance -- hybrid
