What is Dijkstra's Algorithm and how is it used in computer networks?
Dijkstra's Algorithm is a graph search algorithm that finds the shortest path between nodes. In computer networks, it's used for routing data efficiently.
Can you explain how the algorithm works step by step?
Sure! It starts by marking the initial node with a distance of zero and all others as infinity. Then, it explores neighboring nodes, updating their distances based on the shortest known path.
What are some real-world applications of Dijkstra's Algorithm?
It's widely used in network routing protocols like OSPF and in GPS systems for finding the shortest driving routes.
Are there any limitations to Dijkstra's Algorithm?
Yes, it doesn't work well with negative weight edges and can be inefficient for very large graphs compared to other algorithms.
