1. What is Computer Hardware? - Components, Definition & Examples
Computer hardware is the collection of physical parts of a computer system. This includes the computer case, monitor, keyboard, and mouse. It also includes all the parts inside the computer case, such as the hard disk drive, motherboard, video card, and many others. Computer hardware is what you can physically touch.
2. What is a Computer System Unit? - Function, Components & Definition
A computer system unit is the enclosure that contains the main components of a computer. It is also referred to as a computer case or tower. Read on to learn about the functions and components that go into a computer system unit.
3. How to Safely Start Up & Shut Down Computers
Learn how to start up and shut down a computer, and the precautions you can take to avoid losing data. Discover the steps that computers themselves follow during start up and shut down.
4. 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.
5. What is a Motherboard? - Definition, Function & Diagram
The motherboard is a sheet of plastic that holds all the circuitry to connect the various components of a computer system. Learn how the motherboard functions to make all the other components work together.
6. Central Processing Unit (CPU): Parts, Definition & Function
The central processing unit (CPU) is the brain of your computer. It handles all the instructions you give your computer, and the faster it does this, the better. Learn about how a CPU processes instructions and how computer engineers are continuously coming up with ways to make it go faster.
7. 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).
8. What Are Peripheral Devices of a Computer? - Definition, Examples & Types
A peripheral device connects to a computer system to add functionality. Examples are a mouse, keyboard, monitor, printer and scanner. Learn about the different types of peripheral devices and how they allow you to do more with your computer.
9. Network Interface Card (NIC): Types, Function & Definition
To connect to a network, a computer uses a network interface card (NIC). A NIC controls the wired and wireless connections of a computer to exchange information with other computers and the Internet.
10. LAN Card: Definition, Function & Types
In this lesson, you'll be learning about LAN (or Local Area Network) cards, which is used to connect computers to networks. After the lesson, test your knowledge with a quiz.
11. What Is a Video Card? - Function, Definition & Types
A video card is used to process images so they can be displayed on your monitor. A good video card can make a big difference in the quality of your graphics, so this is particularly important if you play games or work with photography and video.
12. 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.
13. 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.
