Physical Network Topologies Flashcards
What issues are associated with Bus Topology?
The main one is low fault tolerance, but it also is hard to troubleshoot and move.
What is fault tolerance?
Fault tolerance is the capability of a network to respond to and resolve an issue.
What physical topology can be identified by a hub, switch, or access point occupying a central point in the network through which workstations are connected?
Star (hub and spoke) topology.
What are the main benefits to star topology?
Fault tolerance and scalability.
It is more fault tolerant; a cable disruption only affects one machine. It is also far more scalable; simply run a new cable.
What is the main concern with star topology?
Single point of failure (hub/switch)
Why isn’t Ring Topology used anymore?
it’s not fault tolerant, difficult to reconfigure and troubleshoot, and expensive.
What is a collision?
When data from two hosts trying to communicate simultaneously collides and gets lost.
Why isn’t mesh topology used in corporate LANs anymore?
It is complicated to manage, as every device on the network must be directly connected if it is a true mesh topology. This is why a hybrid mesh is usually used on modern WANs.
What is the only reason to still use a true mesh topology?
It’s fault tolerance is pretty unbeatable.
What is a point to point connection?
Direct connection, either hard wired or wireless, between two devices.
What is a point to multipoint connection?
fucking obvious isn’t it?
What is a network backbone?
Network backbone is the means by which segments are connected to the server(s).
What are network segments?
small section of the network.
What is the name of the boundary in which on entity hands off connection to another?
Demarc or demarcation point
What is the physical point in which a service provider can run diagnostics?
smart jack
