How many bits are borrowed from the default host portion of the address to create...

In a Class B network, the default subnet mask is 255.255.0.0, which allocates:​

16 bits for the network portion

16 bits for the host portion​

When the subnet mask is changed to255.255.255.0, it becomes:​

24 bits for the network portion

8 bits for the host portion​

This indicates that8 bitshave been borrowed from the host portion to create additional subnets. Borrowing bits allows for the division of the original network into smaller sub-networks, enhancing organization and security within the network.​
