World of Computer Networking Your CCNA start - Number of Hosts Needed in a Network - Example 1

The video tutorial explains how to find the network prefix address by converting IP addresses and masks from decimal to binary, performing an AND operation, and converting back to decimal. It uses examples to demonstrate calculating the number of hosts in a network, emphasizing the importance of avoiding large broadcast domains. The tutorial also covers the mathematical process of determining available host IP addresses, highlighting the subtraction of network and broadcast addresses.

What is the first step in finding the network prefix address?

• Convert binary numbers to decimal

• Perform an OR operation

• Convert decimal numbers to binary

• Subtract two from the total

In a Class B network with a 16-bit mask, how many host bits are available?

• 8

• 24

• 16

• 32

How do you calculate the number of available host IP addresses in a network?

• 2 to the power of host bits plus 2

• 2 to the power of total bits

• 2 to the power of host bits minus 2

• 2 to the power of network bits

Why is it not recommended to have a large number of hosts in the same network?

• It increases the number of available IP addresses

• It reduces the broadcast domain size

• It leads to large broadcast domains and many broadcasts

• It simplifies network management

What are the two addresses that are subtracted when calculating available host IPs?

• Network and gateway addresses

• Broadcast and gateway addresses

• Network and broadcast addresses

• Gateway and DNS addresses
