OSPF is a routing protocol used to exchange routing information within a single autonomous system. OSI model is a conceptual model used to describe network communication.

• OSPF stands for Open Shortest Path First

• It is a link-state routing protocol

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

• OSPF is used within a single autonomous system

• OSI model has 7 layers: Physical, Data Link, Network, Transport, Sessi...read more

VLAN is a logical grouping of network devices and Switching is the process of forwarding data packets between network devices.

• VLAN stands for Virtual Local Area Network

• It allows network administrators to group devices together based on their function or location

• Switching is the process of forwarding data packets between network devices

• Switches use MAC addresses to determine where to forward packets

• Switching can be done...read more

Fibers are thin strands of glass or plastic used to transmit data over long distances in networking.

• Fibers use light to transmit data instead of electrical signals.

• They have a higher bandwidth and can transmit data over longer distances than copper cables.

• Fibers are used in long-haul networks, data centers, and even in some home internet connections.

• Examples of fiber optic cables include single-mode and multi-mode fibe
