Binary to Octal Conversion Concepts

This video tutorial explains how to convert binary numbers into octal numbers. It begins with an introduction to the conversion process, followed by three examples demonstrating the conversion of different binary numbers into octal. The tutorial emphasizes grouping binary digits into sets of three and calculating their octal equivalents by adding the values associated with each binary digit.

What is the first step in converting a binary number to an octal number?

• Multiply each digit by 8

• Add all the binary digits

• Group the binary digits in pairs

• Group the binary digits in threes

In the binary number 110101, what is the octal equivalent of the group 101?

• 5

• 4

• 6

• 7

How do you determine the value of a binary group like 100?

• Use the powers of 2 for each position

• Add the digits directly

• Convert directly to decimal

• Multiply each digit by 2

When converting a 7-digit binary number, what should you do if the last group has less than 3 digits?

• Convert it directly

• Add zeros to the right

• Add zeros to the left

• Ignore the last group
