What else can I help you with?
What is the star network with an additional networking device connected to the main networking device?
hierarchical (extended) star topology
What are the disadvanteges of a star topology?
If the center device(hub) is failed, the total network is dead.
What device is at the center of extended star?
i have no idea, sorry!!
Which physical topology uses a central device with drop cables extended in all directions?
It sounds to me like you're describing a star network.
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.
A physical topology specifies device types?
a physical topology specifies what
Which topology provides each device with a point to point connection to every other device in the network?
star topology
Which network topology is secure?
Mesh topology is the most secure topology bcoz in mesh topology each device has a dedicated link to others .
Why is the star topology the best topology?
Scalability and reliabillty of star topology makes it the best, easy to remove or add a device.
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 type of network has the computers connected to a hub in the center?
A center connectivity device means a star topology is being used. If it is a managed hub such as a MAU or MSAU unit, then it is a token ring network.
Which type of network topology has a central connection device which each computer on the network is connected to?
STAR Topology
