The OSI Model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven layers.

• It stands for Open Systems Interconnection Model.

• It helps in understanding how data is transferred over a network.

• Each layer has specific functions and interacts with adjacent layers.

• Examples of layers include Physical, Data Link, Network, Transport, Session, Presentation, and Application.

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

• OSPF is a link-state routing protocol

• It uses Dijkstra's algorithm to calculate the shortest path

• OSPF routers exchange link-state advertisements (LSAs) to build a topology database

• It supports VLSM (Variable Length Subnet Masking) and CIDR (Classless Inter-Domain Routing)

• OSPF areas are used to divide large networks into smaller, more manageable segments
