What is STP, What is OSPF, Subnetting, etc.

Question

Accepted Answer

STP is a network protocol that ensures a loop-free topology, OSPF is a routing protocol that uses link-state routing algorithm, Subnetting is dividing a network into smaller subnetworks.

STP (Spanning Tree Protocol) prevents loops in Ethernet networks by blocking redundant paths.
OSPF (Open Shortest Path First) is a routing protocol that calculates the shortest path to a destination based on link costs.
Subnetting involves dividing a larger network into smaller subnetworks to improve efficiency and security.
Example: STP ensures only one active path between switches to prevent broadcast storms.
Example: OSPF dynamically adjusts routing tables based on network changes.
Example: Subnetting a network into smaller segments like 192.168.1.0/24 into 4 subnets of /26.
