World of Computer Networking Your CCNA start - Number of Hosts Needed in a Network - Example 3

The video tutorial explains how to calculate the number of hosts in a network using binary math. It covers the steps to determine the network and broadcast addresses, and how to find the available IP addresses in a network with a specific mask. The tutorial concludes with a brief introduction to subnetting.
