Subnet

Okay kiddo, imagine you have a big group of friends and you want to invite them to your birthday party. But you don't want them to all come at the same time because your house might not be big enough to fit everyone. So you tell some of your friends to come at 2pm, some at 3pm, and some at 4pm. This way, your house will never be too crowded and everyone can have a good time.

Subnetting is kind of like that. Imagine all the devices on a network (like computers, phones, and printers) are your friends at your birthday party. A subnet is like a group of devices that are all invited to the party at the same time. Instead of using time slots, we use numbers to decide which devices are in which group.

When we subnet a network, we divide it into smaller groups, or subnets. Each subnet uses a different range of numbers to identify the devices within it. This helps to organize the devices and make sure that they can all communicate with each other without getting confused.

Just like your friends might have different gifts or activities at your party, devices on different subnets might have different settings and permissions on the network. Subnetting can help make sure that everyone gets what they need and nobody accidentally messes things up for anyone else.

Overall, subnetting helps to manage network traffic so that devices can communicate efficiently and effectively. It's like dividing your birthday party into smaller groups so that everyone can have a great time!
