Networks Principle and programming languages 1st meeting

Types of  Network topologies

1. Bus Topology - use a common backbone to  connect all devices.
2. Ring Topology - every device has exactly two neighbors for communications purposes
3. Star Topology - features a central connection point called a hub node that may the net work hub, switch , router.
4. Tree Topology - integrate multiple star topologies together onto a bas
5. Mesh Topology - involve the concept of routes

Different Types of Networking

1. LAN- Local Area Network- connects network devices over a relatively short distance.
2. WAN- Wide Area Network- Spans a large physical distance. the Internet is the largest.  WAN- geographically dispersed collection of LAN. Router connects LANs to a WAN.
3. Home Networking
