About This Chapter
Hardware and Systems Technology
How can you be sure that your computer has every gizmo and gadget that you'll need? To begin with, you'll need to learn a bit more about those so-called gizmos and gadgets, starting with their names. Our video lessons will help you to define all the parts of your computer, from the inside to the outside, including all those extras that may be attached to your computer.
To begin your introduction to computer hardware, lessons will cover the different components of a system. You'll learn the characteristics and functions of processors and memory devices. Find out the meaning of terms, such as CPU, control unit and ALU. Uncover what it takes to make your computer store any information you need.
Unravel the idea of computer storage by looking at internal and external devices. Learn more about optical, magnetic and semiconductor storage, and discover what a primary storage unit is and how secondary storage devices are used.
Keep exploring the lessons to discover computer input and output devices. You'll take a look at important input devices, like keyboards, mice, video devices and audio systems. Output devices, such as speakers, monitors and printers, are also covered. As you develop your understanding of these devices, you'll understand what you need to help operate your computer, create videos, listen to music and perform many other actions.
Lessons will wrap up with a discussion of how data is digitally represented by computers. Get to the definitions of terms including bit, byte, digital, analog and ASCII. Once you complete these lessons, you'll feel more at ease with your computer and understand the different parts that make it work. Thanks for watching!
1. Computer System Components: Computer Parts & Functions
Are you ready to buy a computer? Let's take a trip through the components of a computer for some advice. We'll learn about the motherboard, memory, storage, connectivity and peripherals.
2. Computer Memory and Processing Devices: Functions & Characteristics
Have you ever wondered how your computer operates - specifically, where it stores all the information it needs to run? This lesson will answer that question by explaining the general functions of the central processing unit (CPU), random-access memory (RAM) and read-only memory (ROM).
3. External and Internal Storage Devices: Optical, Magnetic & Semiconductor Storage
Let's explore the capacity of internal and external storage devices. We'll learn how optical, magnetic and semiconductor storage works, as well as identify some examples of storage devices.
4. Computer Input Devices: Keyboards, Mice, Audio & Video
What input devices do you use on a daily basis? We'll take a look at the common keyboard and mouse devices as well as other methods of input like audio and video.
5. Computer Output Devices: Monitors, Speakers, & Printers
So you've entered information into your computer. How do you get it back out? Here's a look at output devices such as monitors, speakers, printers and eBooks.
6. ASCII and Unicode to Represent Characters in Binary Code
A computer can think at speeds of over a billion machine cycles per second. However, no spoken language is a computer's native tongue. Learn how a computer translates analog to digital signals in this lesson.
7. What Is Random-Access Memory (RAM)? - Definition & History
Random-access memory (RAM) is a type of storage for computer systems that makes it possible to access data very quickly in random order. The term RAM has become associated with the main memory of a computer system.
