Explanation:
Detailed explanation-1: -Network security can be boosted. With different subnets within your larger network, you are more aware of route maps and can more easily identify potential threats. With subnets, devices will not be able to access the whole network, and companies can dictate which hardware and users have access to more sensitive data.
Detailed explanation-2: -To calculate the number of possible subnets, use the formula 2n, where n equals the number of host bits borrowed. For example, if three host bits are borrowed, then n=3. 23 = 8, so eight subnets are possible if three host bits are borrowed.
