Chapter 3: Network Topology

1. What is STAR TOPOLOGY?

Star topology is a network topology where computers are connected in a linear manner.

Star topology is a network topology where all computers are connected to each other directly.

Star topology is a network topology where computers are connected in a circular fashion.

DefinitonStar topology is a network topology which can connect the computers by the central devices such as switch and hub.

Star topology is a type of network configuration where all devices are connected to a central hub or switch, allowing for easy management and troubleshooting.

Explanation

Star topology is a type of network configuration where all devices are connected to a central hub or switch, allowing for easy management and troubleshooting.

2. What is BUS TOPOLOGY?

A topology where all computers are connected in a mesh network where each computer connects to every other computer.

A topology where all computers are connected in a star pattern with a central hub.

DefinitionThe bus topology is a network topology which includes the trunk or backbone as the connecter to the computers. It is also may includes the the T-connecter and at the end of each backbone has the terminator.

A topology where all computers are connected in a circular manner.

Bus topology is a network layout where all computers are connected to a single trunk cable. This type of topology is commonly used in Ethernet networks where each device is connected to the same cable, with terminators at each end to prevent signal reflection.

Explanation

Bus topology is a network layout where all computers are connected to a single trunk cable. This type of topology is commonly used in Ethernet networks where each device is connected to the same cable, with terminators at each end to prevent signal reflection.

3. What is a ring topology in networking?

In a ring topology, information is broadcasted to all computers simultaneously.

A star topology involves connecting computers in a circular shape.

In a ring topology, computers are connected in a linear fashion.

Definition-The ring topology is a network topology which connects computers in a circular shape and sometimes the information that travels through the circulation called the "token".

A ring topology is specifically characterized by circular connections where each computer has exactly two neighbors for communication. The 'token' is passed along the network in a sequential manner, ensuring orderly communication.

4. What is network topology?

Network topology is the physical layout of computers and cables.

Network topology refers to the software applications used in networking.

Network topology is the process of setting up a wireless network.

Network topology is the measure of network speed and bandwidth.

Network topology specifically refers to the physical layout of computers and cables in a network, describing how devices are connected and the structure of the network itself.

Network topology specifically refers to the physical layout of computers and cables in a network, describing how devices are connected and the structure of the network itself.

5. What are the disadvantages of different network topologies?

Disadvantages of Hybrid Topology- Complicated design and increased risk of network failure.

Disadvantages of Star Topology-Performance and as well number of nodes which can be added in such topology is depended on capacity of central device.
Disadvantages of Bus Topology- It is not suitable for network with heavy traffic.Disadvantages of Ring Topology-If one worksattion or port goes down, the entire network gets affected.

Disadvantages of Mesh Topology- Limited scalability and high cost.

Disadvantages of Tree Topology- Difficult to expand and complex to manage.
