Network Topology
It’s a geometric arrangment of hosts and network devices. Can be physical (cables and PCs’ layout) or logical (informaiton transmission methods).
Bus
To avoid latency, 5 PC max. Thin 10BASE2 (black) or thick 10BASE5 (yellow). 1 failes - all fail.
This is how it looks like on a diagram.
Hub
Options: UTP 10BASET (blue).
Low cost. 1 fails - net still on.
And this is a diagram so dear.
Ring
Options: Thicknet, fiber, optic.
Each node is a repater (token passing). 1 token - 1 network. 1 token is a series of bits containing control information.
Mesh
Options: Thicknet, fiber, optic.
1 fails - net still on.
Hybrid
Star-bus, star-ring
Architecture
Peer-to-peer.
Client-to-server.
Routing
Two types: static (no routing protocols needed) and dynamic (routing protocols needed). Routing protocols can be of distance vector, link state or hybrid. These also can be in autonomous system (IGP) or between autonomous systems (EGP).
