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 topology has a centralized location in which all the cables come together to a central point such that a failure at this point brings down the entire network?
The topology you're describing is known as a star topology. In a star topology, all network devices are connected to a central hub or switch, which acts as the main point of communication. If this central point fails, the entire network becomes inoperable, as no devices can communicate with each other. This design is often used for its simplicity and ease of troubleshooting, but it does create a single point of failure.
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 is starBus topology?
Star bus topology is a network configuration that combines elements of both star and bus topologies. In this setup, all devices are connected to a central hub or switch (like in a star topology), while the data is transmitted along a single backbone cable (like in a bus topology). This design allows for improved performance and easier troubleshooting, as issues can often be isolated to individual connections. However, if the backbone cable fails, it can disrupt the entire network.
What topology is used in local area networks?
Local area networks (LANs) commonly use several topologies, with the most prevalent being star, bus, and ring topologies. The star topology connects all devices to a central hub or switch, facilitating easier management and fault isolation. The bus topology involves a single central cable to which all network devices are connected, while the ring topology connects devices in a circular format, where data travels in one direction. Each topology has its advantages and disadvantages, influencing its selection based on network size and requirements.
Which network topology is complete disrupted when a key central device stops operating?
A star topology is completely disrupted when a key central device, typically a hub or switch, stops operating. In this configuration, all devices are connected to the central device, and its failure means that communication between all connected devices is halted. Without this central point, the network becomes inoperative, preventing data transmission.
