Which LAN topology is characterized by all devices being daisy-chained together with the devices at each end being connected to only 1 other device?
Bus technology. which uses coax wire and terminators.
When only a few microcomputers are to be linked then the bus network is typically used?
Bus topology LANs are very rare these days. It would be easier to use a star topology than a bus topology for a few devices.
What are the characteristics of the star topology?
In a star topology, each device connects to a central network connectivity device such as a hub, switch, or router. These devices would be connected as a "star" (points on a star). The other characteristic of a star topology is that a failing connection will only affect the failed device unless that device is the connectivity device. This means that in most cases a failing device on a star will not take down the entire network. Another characteristic of a star is that they are easily expandable and scalable.
Which network topology will allow all devices to continue to communicate with each other should a network cable fail A bus B extended star C mesh D ring E star?
Only a Mesh will allow every node to continue to work on a network if one cable does down. In a Star topology, however, only the computer the cable was connected to would lose contact with the network.
Explain the function of crossbar switching system?
In a network, a cross-bar switch is a device that is capable of channeling data between any two devices that are attached to it up to its maximum number of ports. The paths set up between devices can be fixed for some duration or changed when desired and each device-to-device path (going through the switch) is usually fixed for some period. Cross-bar topology can be contrasted with bus topology, an arrangement in which there is only one path that all devices share. Traditionally, computers have been connected to storage devices with a large bus. A major advantage of cross-bar switching is that, as the traffic between any two devices increases, it does not affect traffic between other devices. In addition to offering more flexibility, a cross-bar switch environment offers greater scalability than a bus environment.
What was the advantage of replacing a physical bus topology with a physical star topology using hubs?
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.
How can a physically connected star hub logically be considered a bus network?
in the star topology central system switch or hub act as a central devices and if it fails whole the system will fail, in star topology if one station only transmit at a time other wise the collision will occur and it will broadcast the data like a bus.so it contains the properties like bus that's why said that it is logically a bus
What are devices are connected so that there is only one one path for current to follow?
diode
Which topology is common these days Justify your answer with five reasons?
One of the most popular topologies for Ethernet LANs is the star and extended star topology. It is easy to setup, it's relatively cheap, and it creates more redundancy than the Bus Topology. The Star Topology works by connecting each node to a central device. This central connection allows us to have a fully functioning network even when other devices fail. The only real threat to this topology is that if the central device goes down, so does the entire network. The Extended Star Topology is a bit more advanced. Instead of connecting all devices to a central unit, we have sub-central devices added to the mix. This allows more functionality for organization and subnetting- yet also creates more points of failure. In many cases it is impractical to use a Star Topology since networks can span an entire building. In this case, the Extended Star Topology is all but necessary to prevent degraded signals. Whereas the Star Topology is better suited for small networks, the Extended Star Topology is generally better for the larger ones.
Purpose of star topology?
A star network uses a central server to route data between clients. The central server (or the switching hub) switches data around the network. Data flow between the server and the nodes will therefore be relatively low. A typical star network are mainframe computers. Star topology, also known as star network, is a computer network topology. It is a common network setup where the computers and other devices on the network are connected to a central or master computer, also known as the hub.
How many peripheral devices can be connected to a single USB port?
On a typical setup, only one device can be connected to the ports. However, if you have a special USB port, or a device that will split a USB port, you can connect 2 or more devices.
If one system failed in star topology what happens?
In a star topology only the failed system would have a problem, unless the device was the network connectivity device (on a LAN).In a WAN, if the building was connected through the central building and the central building had a problem then all buildings would be affected. If it isn't the central connection point then only the building with the problem would be affected.
