What happens if the main cable in bus topology fails?

In a bus topology, if the main cable fails, the entire network stops working. This happens because all the devices are connected to a single main cable, which acts as the backbone of the network. If this cable fails, the whole system fails, and data cannot reach its destination or the server.

How movement in ring topology occurs in one direction? In a ring topology, data moves in a single direction ,either clockwise or counterclockwise. Each device is connected to two other devices, forming a closed loop. Each device receives the data, checks if it is the intended recipient, and if not, forwards it to the next device in the loop. This continuous flow of data around the ring is how a ring topology works.

How mesh topology enables data transmission?

In a mesh topology, each node is connected to every other device in the network, creating multiple paths for data transmission. Here, every device has a direct connection to all other devices, so if one device needs to send data to another, it can do so directly without passing through any other device. Since there are multiple paths, if one path fails, the data can use an alternate route, ensuring effective and reliable networking.

How multiple topolgies connects in hybrid topology?

A hybrid topology is a combination of two or more different types of network topologies, such as ring, star, and mesh. Data transmission in a hybrid topology depends on the type of network topology used in each part of the system. For example, if a star topology is used, data first passes through the central hub or switch. If a bus topology is used, data travels through the main cable. In this way, data transmission in a hybrid topology follows the rules of the specific topologies that make it up.

How does a hybrid topology combine the advantages of different topologies?

In a hybrid topology, two or more network topologies are combined together. While implementing this, the hybrid topology takes the strengths of each individual topology and uses them to improve network performance. It does not include or use the weaknesses of any topology in the hybrid design.

What determines whether a network follows a particular type of topology?

This is an important concept. For example, consider two types of logical topologies - logical ring and logical star.

In a logical star, data passes through a central device such as a hub or switch. In a logical ring, data passes from one device to another in a loop until it reaches its destination.

The choice of topology is completely based on the data flow pattern and communication method, which determine whether the network behaves as a logical ring or a logical star — regardless of the physical structure.

Widely used topology and why?

The most commonly used network topology is the Star Topology. In a star topology, all devices are connected to a central device such as a hub, switch, or router.

Features that make it commonly used:

Easy to install and manage High performance Scalable (easy to add new devices) Managed through a central server or device

Commonly used in:

Wi-Fi router setups LAN (Local Area Network) configurations Offices, schools, and home networks.

Least used network topology and why?

The least commonly used or not widely used network topology is the Mesh Topology. In a mesh topology, every device is connected to every other device in the network. While this provides high reliability and fault tolerance, it is very expensive and complex to set up and maintain.

Can a network have a physical star topology and a logical star topology together?

A network can have a physical star topology and a logical star topology together. In this setup, physically, all devices are connected to a central device like a switch or router. Logically, data also passes through that same central device, which controls communication between all devices. So both the structure and the data flow follow a star pattern ,meaning the network has a physical star and logical star topology at the same time.

Which is the most affordable network topology to set up?

The most affordable network topology is the Bus Topology. In this topology, all devices share a single main cable, called the backbone. It uses less cabling, requires no central device, and is cheaper and easier to install than other topologies. It is mainly used in small and simple networks. Bus topology needs minimum cabling, with no need for switches, hubs, or routers, making it easy to set up ,and that’s why it is considered affordable.
