Network Topology

1. What is STAR TOPOLOGY?

BUS TOPOLOGY is a network where all network devices are connected to a single central cable called a bus, with data flowing in both directions.

STAR TOPOLOGY is a network where each individual topology piece of a network is attached to a central node (often called a hub or switch)

MESH TOPOLOGY is a network where each network device is connected to every other network device, allowing for multiple paths for data to travel.

RING TOPOLOGY is a network where each network device is connected to two other devices, forming a circular pathway for data.

The correct answer explains that in a STAR TOPOLOGY, all network devices are connected to a central node, while RING, MESH, and BUS topologies have different structures and connectivity methods.

2. What is BUS TOPOLOGY?

MESH TOPOLOGY is a network setup where each device is connected to every other device in the network.

BUS TOPOLOGY is a specific kind of network topology in which all of the various devices in the network are connected to a single cable or line.

STAR TOPOLOGY is a network layout where each device is connected directly to a central hub or switch.

RING TOPOLOGY is where each network device is connected to two other devices, forming a circular pathway for data.

A bus topology consists of a main cable with all network devices connected directly to it, while other topologies have different structures and ways of connecting devices.

Explanation

A bus topology consists of a main cable with all network devices connected directly to it, while other topologies have different structures and ways of connecting devices.

3. What is RING TOPOLOGY?

BUS TOPOLOGY

RING TOPOLOGY in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node - a ring. Data travel from node to node, with each node along the way handling every packet.

MESH TOPOLOGY

STAR TOPOLOGY

Ring Topology is a network configuration where each node connects to exactly two other nodes in a circular manner, creating a continuous data path. It is different from other topologies such as Star, Mesh, and Bus in terms of structure and data flow.

Explanation

Ring Topology is a network configuration where each node connects to exactly two other nodes in a circular manner, creating a continuous data path. It is different from other topologies such as Star, Mesh, and Bus in terms of structure and data flow.

4. What is a disadvantage of star topology?

If the hub, switch, or concentrator fails, nodes attached are disabled.

Data transfer speed is slower compared to other topologies.

There is a high risk of data collisions in star topology.

It is difficult to add new devices to the network.

In a star topology, all nodes are connected to a central hub, switch, or concentrator. If this central device fails, the nodes attached to it are unable to communicate with each other. This makes the network vulnerable to a single point of failure.

In a star topology, all nodes are connected to a central hub, switch, or concentrator. If this central device fails, the nodes attached to it are unable to communicate with each other. This makes the network vulnerable to a single point of failure.

5. What is a disadvantage of ring topology?

Ring topology is more resistant to network failures compared to other topologies.

All data being transferred over the network must pass through each workstation on the network, which can make it slower than a star topology.

Ring topology allows for easy addition or removal of devices without disrupting the network.

Each workstation has dedicated point-to-point connections, leading to better performance.

Ring topology requires data to pass through every workstation, creating potential bottlenecks and slowing down the network. This is a key disadvantage compared to star topology where data traffic is more efficiently managed.
