CS101 Introduction to Computing Lecture 5 Building A Personal Computer

In this lecture, we explore the essential components that make up a personal computer (PC), from the monitor and keyboard to the intricate parts inside the CPU. We cover critical subsystems like memory, storage, and input/output devices. Students will gain insights into how these components work together, including the motherboard, power supply, and various cards such as video and sound cards. By the end of the session, you'll have a foundational understanding of PC assembly and the crucial roles of each part as a stepping stone to our next discussion on web development.

  1. CS101 Introduction to ComputingLecture 5Building A Personal Computer

  2. During the last lecture … • We found out about the various types, big and small, fast and slow, cheap and expensive. Our main categories were: • Super computers • Mainframes • Servers • Desktops • Mobile computers • We also found out that a modern computer contains the following essential components: • Processor • Memory subsystem • Storage subsystem • Input subsystem • Output subsystem • The Bus

  3. Today’s goal is quite simple … To learn about the various components of the popular personnel computer and how those things are put together to form a PC

  4. PC Parts • Monitor (show cables; the tube) • Keyboard • Mouse (inside) • Speaker/headphone • Microphone • CPU • Front buttons • Backside ports, fan, slots, cables

  5. Inside of the CPU • Power supply/fan & connectors • Motherboard • Bus • Edge connectors • Ports • Video card • Modem • Network card • Sound card • ROM • RAM • Slots • DIMM’s

  6. The Processor Module • The slot on the motherboard • The housing • Fan • Heat sink • Pins (256?), Transistors (10 million?)

  7. What have we learnt today?

  8. Our next lecture will be … … our 2nd Web development lecture in which we’ll learn about how to construct a Web page and make available on the Internet for every one to see In the lecture following that one, i.e. lecture 7, we’ll continue with the discussion that we have had today about the inside of a PC, and our focus will be on the most crucial component found inside a PC, the microprocessor
