Network Topology

The last post remind me about the network topology. Actually, I have received this material at school. But, the material was only theory. I never yet practice it.
Network topology is formed of 2 words. They are network and topology. Based on Wikipedia, network is

a collection of hardware components and computers interconnected by communication channels that allow sharing of resources and information

and in my opinion network is the way to communicate, to share some things via electronics media, plain speak, and the other that can be connecting people.
Second, topology. Topology is similar to map. So, network topology is the map that show the way of communication, sharing resources, between people.
Network topology is divided by 2 categories. They are physical topology and logical topology.
Physical topology explain how the cable formation, computer, and all the network component. And logical topology explain how the data, information, and resources flow.
There are many type of network topology. they are

1. Bus topology
2. Peer-to-peer
3. Star topology
4. Ring topology
5. Mesh topology
