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 network use star topology?

Star topology:- In this topology all PC are connected with the central device. Central may be HUB and SWITCH. Star widely use in all over word. Ring topology:- In this ring topology all PC are connected in the frame of ring are close Ring topology use MSAU each PC has a two never road one is called up Stream and called down stream. It used token passing Matterhorn which implement the token ring network. " Is the best of star topology".

What is dual bus topology?

Start with your basic bus topology, where you have a beginning and an end of the network with however many nodes connected in series between. Now, add an identical bus network, except this time start from the other bus network's end and end at this other network's beginning. That's a dual bus topology. This simply provides a single, fail-safe mechanism to the normal bus topology.

Which topology divides the collision domain and provides full media bandwidth to the hosts in the network?

Sw1-sw2 divides the collision domain and provides full media bandwidth to the hosts in the network.

Number of wires required to connect 'n' machine in ring topology?

for one machine no wire.

for 2 machines one wire.

for 3 machines two wire.

....

similarly for n machine (n-1) wires are required.

How many edges does a octagonal prism have?

Well you have an octagon on each end of the prism, and octagons have 8 sides, so 8 x 2 is 16, and then you have edges connecting the corners of the octagons at the end. There are 8 corners in an octagon, so that's 8 more edges. 16 + 8 = 24 total edges.

An n-gonal prism has 3n edges.

Visio templates - how do you create topology drawings in ms visio?

Using VISIO Templates 2007, you can create some amazing topology drawings. Also, address all your security issues on network IT diagrams when you are performing these drawings using Visio template. In addition, the Visio Toolbox Website will give you more Visio tools to simplify complicated technical diagram and reference materials to increase your investment.

What is the formula for the centroid of a n-dimensional hypersphere?

The centroid is the centre. How you find it depends on what information you have about the hypersphere.
