Routing is the process of selecting the best path for network traffic to travel from one network to another.

• Routing involves analyzing network topology and determining the most efficient path for data to travel

• Routing protocols such as OSPF and BGP are used to exchange routing information between routers

• Routing tables are used to store information about network destinations and the best path to reach them

• Routing can be...read more

Subnetting is the process of dividing a network into smaller subnetworks.

• Subnetting helps in efficient utilization of IP addresses

• It improves network performance and security

• Subnetting is done by borrowing bits from the host portion of an IP address

• Example: 192.168.1.0/24 can be subnetted into 192.168.1.0/25 and 192.168.1.128/25

Subnetting is the process of dividing a network into smaller subnetworks to improve performance and security.

• Subnetting involves creating multiple smaller networks within a larger network by dividing the IP address range.

• It helps in reducing network congestion, improving security by isolating different departments or functions, and optimizing network performance.

• Subnet masks are used to determine which part of an IP ad...read more

Routers connect multiple networks together, while switches connect devices within a single network.

• Routers operate at the network layer (Layer 3) of the OSI model, while switches operate at the data link layer (Layer 2).

• Routers use IP addresses to forward data between networks, while switches use MAC addresses to forward data within a network.

• Routers are typically used to connect different networks, such as a home netw...read more
