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 a set of musical lines?

staff A set of musical lines is called a staff or musical staff; more than one set; i.e. plural , would be staves. A set of musical lines is called a staff or musical staff; more than one set; i.e. plural , would be staves.

What is the definition of conditional expectation in weak topology?

If the network is very basic but much is expected of the network then some people would classify the topography as weak. Appropriately designed and maintained networks are important when they do work and vital when they stop working.

What is a line set?

A "Line Set" refers to the lines that run from the condenser unit in an air conditioning system to the cooling unit inside the house (this is where the blower is also located). There is always one large line, usually 1/2 inch, and a smaller line, usually 1/4inch. They are also insulated with a foam and will be cold once they are filled with freon.

What is a hybrid network topology?

A hybrid is a combination of two or more basic network topologies, such as a star-bus, star-ring, or tiered topology.

How do you daisy chain routers?

Routers perform DHCP, which means the router acts as the "owner" of the network. If a router set it's own IP address to 192.168.1.1, then it will likely assign IPs to computers connected to it in the 192.168.1.x range. If you plug another router into your first router, the second router might have the IP 192.168.2.1, and then assign IPs in the 192.168.2.x range. This is what you want to avoid. Having all your computers on the same 192.168.x network is necessary.

You essentially want to use your second router as a switch. To do this, disable DHCP in the routers admin UI. Then, instead of plugging the source cable (coming from your first router) in the "Uplink" port, plug it into one of the regular 1, 2, 3, 4 etc ports. This will enable your router to pass along IPs from your main router, rather than assign it's own. Plug other devices into 2, 3, 4, etc. You've essentially bridged your routers.

What are consequences if connection fails in 5 devices arrange in a star topology?

Bus runs in a straight line from one network device to another. So if one gets disconnect then the all the devices connected down the line get disconnect.

Star runs to a central device like a switch, so if the switch itself fails then the whole network will be disconnected.

Ring is like a bus except it connects back onto itself. So if one device fails they all fail. The exception is if there is a redundant inside ring like that used in FDDI (fiber ring) then if both get disconnect from one device then they all do.

Mesh is high redundancy. Only one device would be disconnected if all the connections were to fail for that device. You can have many connections to other devices thats why its less likely to fail. The only cause for failure at this point is really the power and if you just don't have any. Even if one of the connections between two devices fail there is no effect on network and they can still communicate through other channels

Why bus topology cost is very less?

Bus topology, as compared to a star topology costs less because less cabling is required to connect multiple devices together.

How do you set points on a ford 302 distributor?

if you googlehow to set points on distributer the first answer is correct, with the cam lobe on the shaft opening the points it should open to 17 thousands

How are euclids discoveries being used today?

Euclidean geometry is the study of points, lines, planes, and other geometric figures. The most prolonged argument over time has been that of the parallel postulate which states: there can only be one line that contains a given point and is parallel to another line.

What is Ring topology and Star topology?

A network topology in which network nodes are connected in a circular configuration. Each nodes Examines the data sent through the ring and passes on data not addresses to it.this iz ring topology

A network layout or design in which each node is connected to a central hub. The hub establishes, maintains and terminates all connections between the nodes. In a LAN, the hub is likely to be a workstation, whereas in larger multi-point networks the hub is more likely to a multiplexer.this is star topology

Which topologies used in supercomputer?

Several different topologies are used in supercomputing. A mesh architecture is one of the more common topologies out there. Mesh architectures are particularly well suited to applied simulations. The canonical example is a simulation of ocean weather patterns where each node in the supercomputer will represent (and handle calculations for) a specific patch of ocean, such as a 10x10 square mile sector. In this example, each patch of ocean must communicate information, such as wind speed and temperature to other neighboring nodes and in turn, must update the sector parameters based on information received by its neighbors.

Other example topologies include the master/slave architecture where one node serves to aggregate and process results from all other nodes. There are also ring topologies, tree topologies, and hypercube topologies. By far the fastest communicating, and most expensive topology is the all-to-all topology where every node is connected to every other node. This works fine in superomputers with 20 nodes, but in the largest supercomputers, trying to connect thousands of nodes each to the other thousands of nodes becomes practically impossible. Hence why there are other topologies.

What is the difference between network types and network topology?

Network topology is the layout pattern of interconnections of the various elements (links, nodes, etc.) of a computer

Example can be

  • Point-to-point
  • Bus
  • Star
  • Ring
  • Mesh
  • Tree
  • Hybrid
  • Daisy chain

And The types of network are categorized on the basis of the number of systems or devices that are under the networked area.

There are two types of networks:

  • Local Area Network: The Local Area Network is also referred as LAN. This system spans on a small area like a small office or home. The computer systems are linked with cables. In LAN system computers on the same site could be linked.
  • Wide Area Network: A Wide Area Network or WAN is a type of networking where a number of resources are installed across a large area such as multinational business. Through WAN offices in different countries can be interconnected. The best example of a WAN could be the Internet that is the largest network in the world. In WAN computer systems on different sites can be linked.

The types of networks can be further classified into two more divisions:

  • Peer-to-peer networks: In this networking system all computers are given equal importance. All the software and data are stored on each computer and accesses to them are given to each user.
