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 wireless topology?

It's a network architecture which employs wireless devices. Compared to "classical" network topology, where the cable is network medium, in wireless networks is the air a network medium. It means, that all data travels through the air.

Wireless topology can be of 2 basic categories:

Ad-hoc = no central device, just a bunch of computers connected together through their wireless network adapters.

Infrastructure = there is a central device called "access point" to which all client computers connect. This access point provides interconnectivity between clients and also sometimes between the wireless and wired network.

What are the good performance of star topology?

because star topology make another computer will continue their working even another computer have a problem or each of the computer cable have the problem..

What is physical layout in the network topology?

netwok topology is firstly the process of configuring computer system and peripherals in other for it to have a maintained and stabled communication link in a network environment. so there must be a layout of configuration and networking environment....

What is topology and which of the most commonly used topology these days and why?

Ethernet is easily the most common topology having replaced token ring in the 90's. Simply because of it's ease of use with CAT5 cabling, cheap networking hardware and not needing any termination.

What is the conclusion of network topology?

The conclusion of network topology is to ensure that the system is working as required. Topology refers to the physical wiring process in a network.

Topology represents a collision-free environment?

This is false, topology does not have any representation in the environment. Topology is a study of mathematical shapes and spaces. It focuses on their constant deformations.

What type of network topology for a small company of 20 employees a bus network or ring network or star network?

Star is more appropriate, it's little bit expensive than for instance ring but it's easier to maintain and the bandwidth is higher (depending on UTP you are going to use).

Does Ethernet use ring topology?

No, today virtually all networks use some variation of a star topology. It's far less subject to failure.

If you were a printer how many points would make an inch?

This could vary from how much you set it up. A printer could go from 50dpi-800dpi. (dpi is dots per inch.) For type setters, 72 points equals one inch.

How many views are possible for an orthographic drawing?

Six views are possible for an orthographic drawing, though three views are usually enough.

How do you prove space as infinite mathematically?

There is no mathematical proof that space is infinite. All we know is that there is an expanding limit to what we can see.

What is the difference between rigid transformation and non rigid transformation?

rigid transformation is for same modality(CT-CT) nad it can only perform translation, rotation and scaling translation.

whereas

non rigid for multimodality and it can do streching and shriking too. it use demon algorithm

.

How many vertices does a octagonal prism have?

6`9`

* * * * *

Neither 6 nor 9. The correct answer is 16. An octagonal prism, not surprisingly, has 2 octagonal bases. Octagon implies 8 vertices. Another octagon, not touching the first gives another 8 vertices. 8 plus 8 = 16!

What does subtracting mean in math?

It means to take a smaller number out of a larger number and the sum is what you have after.

Who invented topology?

Euler made some basic contributions which are now considered topology. However, topology was not recognized as a separate field in mathematics until the twentieth century (several hundred years after Euler.) It would probably be best to say that Poincarre pioneered the subject which became topology.

How do you remove a set of dart points?

If your points aren't too short, the easiest way to remove your dart points is to put the dart with the dart point in a pop-rivet gun, squeeze the trigger and your point will stay in the rivet gun and your barrell will fall out minus the point, easy!

What is the Euler characteristic?

The Euler characteristics was originally derived as a topographical constant related to the surfaces of polyhedra.

According to it, the numbers of vertices (V), edges (E) and faces (F) of a polyhedron are related by the following formula:

V - E + F = 2

What is the difference between absolute continuity and differential continuity?

What is the difference between absolute continuity and differential continuity? Do an individual's experiences affect differential continuity? Provide specific examples

What are types of freehand drawing?

There is orthogonal drawing with your front, side/s and back view of your object. Isometric and oblique for your overall view of the object. And explode to see how you project are connected together or assembled.

Can a multimeter test for continuity in an invisible fence?

Yes, in the buried wire. You'll need to put one end of the probe lead on one end of the wire and the other end on the wire past the point that you think may have a break in it.
