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.

Well, that reminds me of my engineering course :)
Well, it's a mesh topology.

TopologyWhat kind of wiring is commonly used in a bus topology?
A bus topology for a LAN will typically use coaxial cable, either 10Base5 (thicknet) or 10base2 (thin-net) copper wiring.
What is the difference between network and topology?
Group of devices connected together forms a Network & structure (design) in which they interconnect is called Topology.
How does Amazon.com exploit the network effect?
Amazon.com take that effect into account when they use buyer recommendations as the selling point for their products.
Deine the topology and explain the advantage and disadantage of bus star and ring topology?
Topology is the structure that describes how devices in a Network are connected.
Bus Topology: Directly connects all devices to network i.e utilises a single Physical medium for Data transmission between devices.
Star Topology: Connects all devices in network through a Central Network connecting device such as Hubs & Switches.
Advantage of Bus Topology is that less connecting cable is used.
Advantage of Star Topology is that Network can function in case one or more devices fail.
Disadvantage of Bus Topology is that whole Network goes down if one device fails.
Disadvantage of Star Topology is that it requires physical connecting medium from Central device to the connecting device i.e more expensive.
With internalization, one solidifies his or her own beliefs and values in terms of morality as opposed to those of society's as a whole. This may involve self hypnosis or the analyzing a situation in a way that allows the person to feel they are correct in doing so. Internization is the opposite of externalization.
What common network can communicate even if they have different network topologies?
It depends; if topplogy is intended in terms of Local Area Network (LAN), most Ethernet LANs use the same topology which is hub and spoke, where Ethernet switch(es) act as the hub and the spokes are hosts (PC's, servers, printers, IP phones, etc.). If topology is meant in terms of different technologies, e.g. Interconnecting an Ethernet network to a SONET or MPLS network, then a router is required between the two. Another possibility is transporting for instance Ethernet traffic over TDM (SONET or T1/T3) circuits. In such case the Ethernet frames are encapsulated at one end of the circuit using protocols such as GFP, PPP OR HDLC and traffic is de-encapsulated at the other end. Specialized bridges are capable of that, without requiring any IP routing.
What do logical topologies describe?
A logical topology shows how a network is configured logically rather than physically. The main difference is that you could have 10 routers, 25 switches, and 5,000 computers in a logical topology and it doesn't matter where they are on the screen, it matters how they are connected to one another.
Which topology is the best for accounting?
If money are involved you better have a reliable network. For accounting I would recommend hybrid type of network. The best combination is mesh + star. It will provide you redundancy as well as it will not be as expensive and complicated as pure mesh.
A domain is an example of what type of logical network topology?
Domain is client-server logical topology.
In the ring topology what happens if one of the stations is unplugged?
Theoretically, in a ring topology, unplugging one station, interrupts the ring. However, most ring networks use a mechanism that bypasses the station; the ring can continue its operation.
Fault tolerance.
I've run into this problem when utilizing Dell LCD panels and the DVI output. If the monitor is not plugged in when the tower is turned on, the PC does not utilize the DVI and defaults to the VGA. When you plug in the DVI connector the monitor realizes it has been plugged in and the LED will go green. When it does not get a signal from the PC it will go into power save mode and the LED will turn orange. Try plugging in the cable then powering the machine all the way down before restart. If you are running dual displays, ensure the second video card is enabled. Or, worst case scenario, you may simply have a bad video card.
What is the name of the device that should be attached at the end of a cable in a cable topology?
its called a cable
What is an star-wired bus topology?
The common network you have at home where a router controls all data and each computer is independent of the rest, dependent only on the router.

Compare three types network topology?
There are really three basic types of Network topologies. They are Star, Bus, and Ring. Let me explain them to you.
Star - All computers and devices are connected to a centrally located hub or switch. The hub or switch collects and distributes the flow of data within the network. It's better to use a switch than a hub because a switch transmits the data to the intended recipient rather than to all hosts on a network.
Bus - All computers and devices are connected in series to a single linear cable called a trunk or sometimes called a backbone. Both ends of the trunk must be terminated to stop the signal from bouncing back up the cable. Because the bus topology does not have a central point it is difficult to troubleshoot problems. Also, a break at any point along the bus can cause the entire network to go down.
Ring - In this topology, all computers and devices are connected to cable that forms a closed loop. Each computer on this type of topology acts like a repeater and boosts the signal before sending it to the next computer. It transmits data by passing a "token" around the network. Hence this type of network is commonly called a token ring network. Similar to the Bus topology, if one computer fails, the entire network goes down.
