World of Computer Networking Your CCNA start - What is a Network Mask?

The video tutorial explains network masks and their role in IP addressing. It covers the three main classes of IP addresses (A, B, and C) and their default masks, represented in slash notation. The tutorial discusses the division of IP addresses into network and host parts, and how network masks are represented in different notations, including prefix, decimal, and binary. It also explains how to determine if two hosts belong to the same network by comparing their network addresses.

What is the default network mask for a Class B IP address?

• 32

• 16

• 8

• 24

How is a network mask typically represented?

• In ASCII notation

• In hexadecimal notation

• In slash notation

• In octal notation

What is the binary representation of the network part in a network mask?

• Alternating ones and zeros

• All ones

• All zeros

• Random sequence

What is the purpose of comparing network addresses of two hosts?

• To identify their MAC addresses

• To determine their IP version

• To check if they belong to the same network

• To find their subnet mask

How can network addresses be configured on hosts?

• Only statically

• Only dynamically

• Either statically or dynamically

• Through manual input only
