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.

If 20 Routers are Networked with full mesh topology. How many Virtual connections between routers?
For a full mesh between 20 devices, you need a total of 20 (20-1) / 2 connections.

True or false most Ethernet networks are based on the star topology?
True. At the center of the star is a hub, or a switch.
What is the difference between technology and topology?
Topology is the actual layout of the network, for instance, where the routers and other devices are located. That would be the networks topology.
What is the topology used in peer-to-peer network?
Any topology can be used for a peer-to-peer network. The easiest is probably a star topology but it doesn't have to be.
Which connector would be used in a 10BASE2 Bus topology?
BNC connectors, Ts, barrel, 4ways, and the all important terminator.
full mesh WAN
Can a Token Ring and Ethernet use the same physical topology?
No, because they use different methods for data transfer. Token Ring is where the computers are arranged in a sort of Ring Shape. there is no router involved. the packet is sent until the recipient is found. Ethernet networking requires the use of a Router or a Switch, or Multiple computers. The data is transfered to the Router, then sent to the recipient directly. multiple computers can be stringed together in a "Daisy Chain", so they all share the MAC address of the first PC in the chain. This can be used to defeat MAC filtering, but that should be covered in a different questions.
What is the best topology for a cyber cafe?
The best topology for a cyper cafe is Bas topology. hope it helps
The advantage is in fault detection; in a bus topology any break in any wire segment would cause the entire LAN to fail. With a star topology, a break in any wire segment only affects the one client connected to the network.
Explain the following network topologies Bus Star Ring and Mesh You can draw figure to explain?
a topology is a way to connect the network system. we can connect network with different types ring ,bus and mash is a topology or way to show connect network with different types in ring topology the systems which we want to connect in network in the form of ring
Yes...depending on the type of topology.
Topology deals with the mathematical properties of shapes.
What type of device is usually found at the center of an extended star topology?
both hubs and switch can act as a center of a star topology
What is Daisy Chains in logical topology?
Daisy chaining is a term used to denote that one system is directly connected to the next system without any intervening devices. It is usually reserved for linear bus topologies in a network, but can be applied to other things as well, such as SCSI disk hard drives which can be chained together.
How does the token passing work on a token bus?
This answer assumes you are asking about a token ring network. I don't know about any other 'token bus topology'. You can think of this as a group of people (say 10 people) standing in a circle. An (one) envelope is being passed from one person to the next. There is not a "From" or "To" address on the envelope. So it comes in on the left hand (received) and is passed out by the right hand to the next (transmitted) person, ad infinitum. A token ring is a serial topology - a message has to passed from one station to the next. The message is seen at a station. and if the addressing in the message block matches it's addrress, the information within the message is removed and retained by that station, and the rest of the package (token) is transmitted on to the next station. Of course there is no info in there for this next station, so it just re-transmits on, and this package is passed around, and around, and around. If a station has someting to transmit out, i.e. a browser request or a file request to a network drive, etc, it waits until the empty token get around to it, captures the token to put in the addressing and message blocks, then transmits. The appropriate gateway will capture it for a browser request, or a server will intercept it for a file request. Again - notice this is a serial topology, one station after the next. But it is quick - either 4 or 16 Mbps. Since it is serial, there should never be a colision, and it should be very reliable, very fast. Unfortunately, the connectors for the cables at the wall stand out pretty proud, and are prone to getting bumped, knocked, kicked out of the wall connection. They are designed to not break the ring if this happens, but of course, that station is off line (same as removing the enet cable connector from the wall).
