Summary of How Computers Work: Computation (Part II)

00:00:00 - 00:10:00

This video explains how computers work by showing how an adder circuit is used to add two bits together. The carry output of the one adder is linked to the carry input of the next, and so on, in a chain of 64 one bit adders. This is how computers can add very large numbers very quickly.

• 00:00:00 In this video, computer circuitry is shown being used to perform simple operations. The three basic gates, or, and not, are introduced, and each is used in a different way. The adder is shown as an example of how these gates work together to perform calculations or decisions.
• 00:05:00 This video explains how computers work by showing how an adder circuit is used to add two bits together. The carry output of the one adder is linked to the carry input of the next, and so on, in a chain of 64 one bit adders. This is how computers can add very large numbers very quickly.
• 00:10:00 In this video, the different components of a computer are explained. The processor, control unit, and system memory are all explained, as well as the clock and buses. The microprocessor is shown in action, with the fetch execute cycle explained.
