Question 327Electricity & Electronics - Assistant Engineer

The correct answer is A) Mesh. The mesh topology features point-to-point interconnection between all communicating devices, which makes it the least vulnerable to a break in communication. If one connection fails, the devices can still communicate through alternative paths, ensuring continued network functionality. This redundancy and resilience are the key advantages of the mesh topology compared to the other options. The bus and star topologies are more vulnerable to communication breaks, as a failure in the central or shared communication line can disrupt the entire network. The ring topology is also vulnerable, as a break in any single connection can bring down the entire ring.
