Network Principle 3rd meeting

Today, we made the past blog. Sir was not able to come so its free. after doing the past blog class is done. dismiss, have time to spend  with kadayawan.

Network Principle and Programming languages 2nd meeting

During our 2nd meeting we had a discussion about the different networking devices.

Such as

1. router used to connect networks together
2. switches add more intelligence to transfers management
3. hub connects a group of host

also the 5 network topologies including the LAN, WAN, MAN

after the discussion we did a short quiz.

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
