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.
What type of topology used in schools?
In schools, a common networking topology used is a star topology. This setup involves connecting individual devices to a central switch or hub, facilitating efficient communication between devices. This topology offers ease of connectivity and centralized management, making it suitable for educational environments.
If central device fails in star topology?
In a star topology, if the central device (typically a switch or hub) fails, all connected devices lose communication with each other, as the central device acts as the main point of connectivity. However, individual devices can still function independently; they just cannot communicate with others on the network. This makes the system vulnerable to a single point of failure, but the star topology is beneficial for easy troubleshooting and isolation of devices. Replacing or repairing the central device restores network functionality.
What is true of cellular topology?
It consists of a number of hubs that form geographical cells for connections. Users and devices can roam from cell to cell in the network. It uses point-to-point and multipoint connections.

How star topology works?
In a star topology, all devices are connected directly to a central hub or switch. This central device manages the flow of data between all connected devices, minimizing network collisions and enabling easy addition or removal of devices without affecting the network as a whole. However, if the central hub fails, the whole network can be affected.
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 three topologies is the PSTN based on?
The Public Switched Telephone Network (PSTN) is primarily based on three topologies: the star topology, the ring topology, and the mesh topology. In a star topology, all devices connect to a central hub or switch, facilitating straightforward communication. The ring topology connects devices in a circular fashion, allowing data to pass in one direction, while the mesh topology offers multiple pathways between nodes for redundancy and reliability. Each topology serves distinct purposes in the overall structure of the PSTN.
Is the star topology for a cable layout?
Yes, the star topology is a type of network layout where all devices are connected to a central hub or switch. This configuration allows for easy addition or removal of devices without disrupting the network. It also enhances network performance, as data is transmitted directly between the central hub and devices, reducing the chances of packet collisions. However, if the central hub fails, the entire network becomes inoperable.
What kind of topology is used by network that connects all its computers and communications devices to a central server?
The topology used in a network that connects all its computers and communication devices to a central server is called a star topology. In this configuration, each device is connected individually to a central hub or switch, allowing for efficient data transmission and easy management. If one connection fails, it does not affect the rest of the network, making it a reliable choice for many setups. However, if the central hub fails, the entire network becomes inoperable.
What physical network topology has the inherent weakness of a single point of failure?
The physical network topology that has the inherent weakness of a single point of failure is the star topology. In a star topology, all devices are connected to a central hub or switch. If this central device fails, the entire network becomes inoperable, as all communication relies on it. This makes the network vulnerable to disruptions if the hub experiences any issues.
