In computer science, which graph data structure is commonly used to represent networks and connections between objects?

  1. Adjacency List

  2. Incidence Matrix

  3. Spanning Tree

  4. Eulerian Path


Correct Option: A
Explanation:

An adjacency list is a graph data structure that represents a graph as a collection of vertices, where each vertex is associated with a list of its adjacent vertices.

In social network analysis, what type of graph is used to represent the relationships between individuals in a social network?

  1. Directed Graph

  2. Undirected Graph

  3. Weighted Graph

  4. Complete Graph


Correct Option: B
Explanation:

In social network analysis, an undirected graph is commonly used to represent the relationships between individuals, where each edge represents a connection between two individuals.

In transportation and logistics, what graph algorithm is used to find the shortest path between two locations in a road network?

  1. Dijkstra's Algorithm

  2. Floyd-Warshall Algorithm

  3. Kruskal's Algorithm

  4. Prim's Algorithm


Correct Option: A
Explanation:

Dijkstra's algorithm is a graph algorithm that finds the shortest path between a single source vertex and all other vertices in a weighted graph.

In electrical engineering, which graph model is used to analyze electrical circuits?

  1. Circuit Graph

  2. Kirchhoff's Current Law

  3. Ohm's Law

  4. Thevenin's Theorem


Correct Option: A
Explanation:

A circuit graph is a graph model used to represent an electrical circuit, where vertices represent circuit elements (such as resistors, capacitors, and inductors) and edges represent connections between these elements.
