Subnet

A subnet, or subnetting, is a way of dividing a larger computer network into smaller, manageable parts. Think of it like creating neighborhoods within a city, where each neighborhood has its own streets and addresses. This helps organize the network more efficiently, improves security, and reduces traffic. By assigning specific address ranges to each subnet, devices can communicate more quickly and securely within their group, while still connecting to the overall network when needed. Subnets are essential for efficiently managing large networks, such as those used in organizations or internet infrastructure.
