Understanding Binary Numbers

This video tutorial by Edie from Practical Networking introduces the binary number system by comparing it to the familiar decimal system. It explains how to count in both systems, highlighting the rules and similarities. The tutorial then demonstrates how to convert binary numbers to decimal and vice versa, using examples and exercises to reinforce learning. The video concludes with a summary of key concepts, emphasizing the importance of understanding binary in computing contexts like IP addresses.

What is the primary difference between the binary and decimal number systems?

• Binary uses letters, while decimal uses numbers.

• Binary is used for text, while decimal is used for numbers.

• Binary uses two digits, while decimal uses ten.

• Binary uses ten digits, while decimal uses two.

In the decimal system, what happens when you run out of digits in a column?

• The column resets to 1 and the next column decrements by 1.

• The column resets to 1 and the next column increments by 1.

• The column resets to 0 and the next column increments by 1.

• The column resets to 0 and the next column decrements by 1.

Why is the range of an 8-bit binary number from 0 to 255?

• Because 8 bits can represent 256 different values.

• Because 8 bits can represent 1024 different values.

• Because 8 bits can represent 512 different values.

• Because 8 bits can represent 128 different values.

Why will you never see an IP address with the value 256?

• Because IP addresses are limited to 512 due to 9-bit binary representation.

• Because IP addresses are limited to 128 due to 7-bit binary representation.

• Because IP addresses are limited to 255 due to 8-bit binary representation.

• Because IP addresses are limited to 1024 due to 10-bit binary representation.
