Summary of How Computers Work: Information (Part I) (2012)

00:00:00 - 00:10:00

This video explains how computers work by exploring how information is stored in binary. We see that numbers and colors can be represented using just three bits, and that text can be stored in a computer in the same way. Next, the video examines how computers perform calculations and make decisions based on this binary information.

• 00:00:00 Computers are made up of switches that are controlled by transistors. Binary is a way of representing numbers using only two digits, 0 and 1. When the electricity is switched off, it corresponds to a zero, and when the electricity is switched on, it corresponds to a 1. An example of a number written in binary is 13, which is written as 100101.
• 00:05:00 In this video, we learn how computers work by exploring how information is stored in binary. We see that numbers and colors can be represented using just three bits, and that text can be stored in a computer in the same way.
• 00:10:00 This video explains how computers use binary to store and represent numeric information. The video covers how different schemes are devised to store different types of information, including colors and text. Next, the video examines how computers perform calculations and make decisions based on this binary information.
