Question

In a ________ topology, if there are n devices in a network, each device has n-1 ports for cables.

• A. Mesh
• B. Bus
• C. Star
• D. Ring

Answer 1

The Correct Option is A

A mesh topology in computer networking establishes a complete interconnection between all devices. Consequently, each device must have a direct link to every other device. With n devices in the network, each device necessitates connections to n-1 other devices, requiring n-1 ports per device.

The following briefly describes the topologies presented in the options:

• Mesh Topology: Every device connects to every other device, utilizing n(n-1)/2 total cables.
• Bus Topology: A solitary communication line is shared among all devices.
• Star Topology: Devices connect to a central hub, not to each other directly.
• Ring Topology: Devices are arranged circularly, with each connected to two adjacent devices.

Thus, in a mesh topology, with n devices, the requirement for each device to connect to n-1 other devices aligns with the specified condition.
