Final answer:
Subnetting is the process that combines several small subnets to form a larger network.
Step-by-step explanation:
The process that combines several small subnets to form a larger network is called subnetting.
Subnetting allows for the division of a single network into multiple smaller networks, which can help with network management and address allocation. This is commonly done by borrowing bits from the host portion of the IP address and using them to create additional network addresses.
For example, if you have a Class C network with a default subnet mask of 255.255.255.0, you can subnet it into smaller networks by borrowing some bits from the host portion. This allows you to create multiple subnets with their own network addresses, which can communicate with each other using routers.
