What is subnetting and router work on which layer

Question

Accepted Answer

Subnetting is the process of dividing a network into smaller subnetworks. Routers operate at the network layer (Layer 3) of the OSI model.

Subnetting involves creating multiple smaller networks from a single larger network by dividing the IP address range.
It helps in efficient utilization of IP addresses and improves network performance by reducing broadcast traffic.
Routers operate at the network layer (Layer 3) of the OSI model and are responsible for forwarding data packets between different networks.
They use routing tables to determine the best path for data packets to reach their destination.
For example, a router can connect a local network to the internet by forwarding data packets between the two networks.
