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 are the advantages of ring topology?
The advantages of ring network are:
- It is a truly distributing but processing system.
- If any one of the computer fails then the transmission continues from the alternate computers.
What kind of topology is susceptible to signal bounce?
A Bus

the inventor of star topology is Sean Ross Remigio that connect the pc to stars.
What are the advantages of a multi point connection and point-to-point?
generally its used for fail-over and reliability. obviously the more connections you have the more reliable your connection however you also have to be aware that the more connections you have on multi-point you also have more security risks involved versus point-to-point connections in which there is only one port to watch and secure which will lower your total surface of attack area.
What topology does the internet use?
The internet uses a very complex topology, due to the massive number of nodes and the high redundancy that is characteristic of high availability systems like the internet. Different parts of the internet look like different topologies. The internet would be best approximated as a mesh topology.
For an image of a simple mesh topology, and a discussion of the different possible network topologies, see the wikipedia article in the links below.
What are the Advantages and disadvantages of point to point topology?
the advantage of information points:
- the information points allow you to find where you need to go. e.g. tourists sites, view points, ect.
- it takes less time to know where you are going, within seconds you know where you need to go
- many of these points are scattered all over therefore easy access
the disadvantage of information points:
- it might be closed on the day you go to it.
- some companies may not be able to afford them as they do cost alot.
Cables used in a star topology?
A star topology is a method of connecting several computers to one another in a network. The cables used in a star topology are twisted pair cables or coaxial cables. Coaxial cables would be the cheapest solution.
Mesh topology minimum required number of computers?
The minimum needed to make the mesh. "Mesh" could refer to several types of groups of computers. There is grid computing, where a large number of small computers all work in parallel. Modern supercomputers, like those used by physicists and weather forecasters (seriously), use grids. Another is distributed computing. Nearly identical in description, the difference is in parlance. Grid may refer to large numbers of computers at one company under control of a dedicated group, where distributed computers usually means dispersed computers. An example might be many computer systems at top research universities working on the same problem. Another is cloud computing. Clouds are groups of computers not necessarily working together on something. The Internet is one example. Seti@Home is famous for harnessing the individual power of millions of (simple, low-power) computers throughout the Internet cloud to create an ultrapowerful distributed grid. You no longer need to create your own supergrid software. You can hire a company like grid.org to solve your problem. For example, analyzing chemicals to see if they'd have any effect on cancerous cells.
Do you required to use any topology in multipoint connection?
Sure, the machines have to be connected somehow. A star topology is quite common.
Consideration of choosing network topology?
Considerations for selecting a topologySelecting an appropriate topology for your deployment environment depends upon several factors.
When you select a topology pattern, consider the following factors:
- Available hardware resources
- Application invocation patterns
- Types of business processes that you plan to implement (interruptible versus non-interruptible)
- How heavily you intend to use the Common Event Infrastructure (CEI)
- Individual scalability requirements
- Administrative effort involved
For n devices in a network what is the number of cable links required for a star topology?
15 usually but it can change over time
What network topology is mostly used in homes and businesses?
The network in the secondary building should also be star topology. It is the most common and very reliable. There will be twelve desktop computers in the building which should be connected to each other and the main building as well. So there should be Cat 6 cabling used in this building. The other networking equipment needed in the building is a wireless router which will help the mobility of the employees, a networking switch for all the workstations and the wall sockets into which the Ethernet cables will be plugged in. There will also be two sockets for the printers. There will be VoIP phones on the desks with the computers
What is the function of bus topology?
The bus topology is one of the four main topology types for networking. It allows systems to be connected in a straight line without any other network connectivity devices. As a result, it is easy to construct and needs very little in the way of configuration, and is inexpensive compared to other topologies.
The main result of any topology is to connect clients together in order to share resources.
What network topologies are most commonly used on today's networks?
star topology. Because they include a centralized connection point; can easily be moved, isolated, or interconnected with other networks; they are, therefore, scalable. For this reason, and because of their fault tolerance, the star topology has become the most popular layout used in contemporary LANs.
What cable often associate with a bus topology network?
Local Area Network Cable usually associate with a bus topology network. In a Bus topology network simple LAN cables are used with LAN Hubs ( i.e. having a collection of LAN ports ) which in turn connect many systems with the server systems. LAN cables are available in various length ranging from 1meter onwards.
What is the logical topology used for ethernet architecture?
Topology: physical ring of trees, logical ring
Which network topology uses least amount of cabling?
As for most things, the lowest cost version of something is also the simplest version of something. In this case, that would be the bus network topology.
What type of topology uses tokens?
Token ring uses star topology . The data token is being passed from one computer to other allowing all the computer to have network access and avoids data collision.
What Types of network topology and give examples of each topology?
Network Topology refers to the way that cables and other pieces of hardware connect to one another. There are four common "base" types of topologies: bus, ring, star, and mesh. There are other types as well, but these are referred to as "hybrid topologies." The most commonly used network topology is a hybrid topology called the Star Bus Topology.
