Most people have interacted with a computer in some way. Whether it is making a phone call, buying something online or writing an email. We do it all using a computer. Even though computers are widely used by everyone, most people do not know how they work. This talk aims to answer that question: How does a computer work?

This presentation will begin with explaining the physics behind the transistor and how those are used to form gates and circuits. These gates and circuits can be utilized as an arithmetic logic unit that can perform addition, subtraction, and do comparisons. Another vital part of a computer is its memory. We will examine how to build memory from circuits and different types of memory as RAM and ROM. Finally, we will talk about what constitutes a computer and the architecture of it.
