Topology
While geometry is primarily concerned with the mathematical properties of spatial objects, topology is concerned with the mathematical properties of those objects under continuous deformations. Please post all questions about topological subjects like homeomorphisms, manifolds, convergence, and connectedness, as well as their broad applications in computing, physics, and graph theory, into this category.

What is the network topologies function?
Network topologies is the means in which a network is structured. There are two types being physical and logical. Logical topology shows how data is delivered between a network.
Which topology is least affected by addition or removal of a node?
Ring Topology is least affected by addition or removal of nodes
(n^2-n)/2-1
star topology,bus topology,ring topology,mesh topology etc...
What happens to communication if a ring topology breaks?
In a ring topology, the nodes on both sides of the break will loop the path (self-healing) back towards the ring, so every node is still communicating with each other.
Which of the following are advantages of a cellular topology network?
-it is relatively easy to troubleshoot problems on this topology
-the network services require no reconfiguration if the network structure changes
-there are no device installation difficulties
Surveying terminology. The measure of distance along a slope. The distance of a line where elevation changes from point 1 to point 2
What are advantages of a cellular topology?
It is relatively easy to troubleshoot problems
The network devices require no reconfiguration if the network structure changes
There are no device installation difficulties
What will happen when a single cable is at fault in any topology?
Mesh topology- a cable at fault not affect others.
Ring topology- a cable at fault, only affect side by side, If main cable at fault ,whole system shut down.
Star topology- a cable at fault, others are not affected. If Hub at fault, whole system shut down.
Bus topology- main cable at fault, system will shut down. a cable at fault,will not affect others.
Which transformation is not a rigid transformation?
A rigid transformation means it has the same size and shape so it would be a dilation
Does dilation change in orientation?
No, it doesn't change orientation because the coordinates do not change weather they are going clockwise or counter clockwise
How do you rotate a figure 270 degrees clockwise around the origin?
* * * * *
or once in the anti-clockwise direction.
Which topology connects each device to a neighboring device?
Ring - A ringtopology connects neighboring nodes until they form a ring. Signals travel in one direction around the ring. In ring topologies, each device on the network acts as a repeater to send the signal to the next device
What are the disadvantages of tree network?
The disadvantages of a tree network are that it requires alot of cable to network and that if the central hub fails then the entire network fails. Also, it is not a prudent expense for a small network.
