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 an Optical Drive? - Definition, Types & Function
An optical drive in a computer system allows you to use CDs, DVDs, and Blu-ray discs to listen to music or watch a movie. Most drives also allow you to write data to a disc, so you can create your own music CDs or create a backup copy of important data.
8. What Is a Hard Drive? - Types, Function & Definition
There are several different types of hard drives for storing software and data files: hard disk drives, solid-state drives and external drives. Learn about how they work and how to select the right drive for a particular computer system in this lesson.
9. What Is a Client-Server Network? - Definition, Advantages & Disadvantages
A client-server network is a central computer, also known as a server, which hosts data and other forms of resources. Clients such as laptops and desktop computers contact the server and request to use data or share its other resources with it.
10. Secondary Storage: Definition, Technology & Devices
When you use a computer, you need to save your work somewhere within or outside the computer itself so that you can access it afterward. Learn what secondary storage is and about some of those devices that are used to store and retrieve data.
11. Software Requirements Validation: Process & Techniques
In this lesson we will learn about software validation and verification, an aspect of project management in which requirements and processes of new software are analyzed to verify that the product meets certain specifications and functions correctly.
12. System Bus in Computers: Definition & Concept
A computer bus transfers data between components of a computer system. In this lesson, we'll talk about how a system bus works, what it's useful for, and what aspects of it make for a good overall performance of a computer.
13. Touchscreen Technology: Definition & Concept
Touchscreen technology makes it possible to interact with a computer system using direct touch of the electronic display instead of using a traditional keyboard and mouse. Learn more about touchscreen technology in this lesson.
14. What is a Graphical User Interface (GUI)? - Definition, Components & Examples
If you use a computer or smart phone, you have used a GUI. In this lesson we will find out what a GUI is, quickly trace its history, and cover its key components. We'll also take a look at some current examples.
15. What is a Mainframe System?
A mainframe computer is a very large computer capable of handling and processing very large amounts of data quickly. They are used by large institutions, such as government agencies and large corporations.
16. What Is a Modem? - Definition & Explanation
Continuous developments in computer technology allow us to stay connected to the world using a modem. A modem is a device that allows the user to send and receive data. This lesson will give you a basic understanding of a modem.
17. What is a QWERTY Keyboard? - Definition & Layout
A computer keyboard uses a standard layout for the keys, known as QWERTY. Learn where this idea comes from and why it has remained the same for more than a century.
18. What Is a Security Policy? - Definition, Examples & Framework
In the IT world, we protect an organization by having a strong, well-defined security policy. In this lesson, we'll examine how to create an effective policy that protects assets, employees, and data.
19. What is a Domain Controller? - Definition & Function
In today's digital world, everything has a password. You need a password to access your computer and shared resources at work. In this lesson, we'll learn about managing passwords in a networked environment through the use of domain controllers.
