What else can I help you with?
What is the physical network topology in which each node is connected to a central point?
It is called a Star topology
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
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.
What is the physical topology when all the computers in a network connect to a central point?
Star
The topology that uses a central hub is?
A star topology.
What is the most commonly used physical topology?
The most commonly used physical network topology is the star topology. This design features a central device, such as a switch or hub, to which all other devices are connected. It is widely used in modern Ethernet networks due to its simplicity and ease of troubleshooting.
Which topology requires a central controller or hub?
Star topology
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.
In topology there is a central controller or hum?
No, there is not.
Which topology uses a central device for point-to-point connections to other devices?
A star topology; a network topology in which endpoints on a network are connected to a common central device by point-to-point links.
What topology connects each node in a line and has no central connection point?
bus topology
Which type of network topology has a central connection device which each computer on the network is connected to?
STAR Topology
