OSPF (Open Shortest Path First) is a routing protocol used to determine the best path for data packets in a network.

• OSPF is used to efficiently route traffic in large networks by calculating the shortest path between routers.

• It is a link-state routing protocol that uses Dijkstra's algorithm to determine the best path.

• OSPF is preferred over other routing protocols like RIP due to its faster convergence time and scalabil...read more

Fiber optics is a technology that uses thin strands of glass or plastic to transmit data as light signals.

• Fiber optics is used for high-speed internet, cable TV, and telephone communication.

• The technology is based on the principle of total internal reflection, which allows light to travel through the fiber without escaping.

• Fiber optic cables are immune to electromagnetic interference and can transmit data over long dis...read more
