Subnetting is really important for making computer networks run better and stay safe. Think of it like organizing your bookshelf—everything works better when it’s neat and tidy.

1. Better Performance:

• Fewer Broadcasts: When you break a big network into smaller parts called subnets, fewer devices get broadcast messages. This means less unnecessary traffic and helps the network run more smoothly.
• Smart Use of Resources: Each subnet can be set up to fit the needs of different departments. For example, the HR team might need more IP addresses because they have lots of devices, while the Sales team might not need as many.

2. Improved Security:

• Keeping Data Safe: Subnetting helps keep important information safe. By making a separate subnet for the finance team, you can add extra security just for them to keep their data protected from the rest of the office.
• Easier Access Control: With subnets, it’s simpler to control who can access what. You can set different security rules for each subnet, which helps lower the chances of someone getting into areas where they shouldn’t.

In simple terms, subnetting is more than just a technical process—it’s a smart way to make everything run better and keep your network secure!
