1. Circuits, Circuit Boards & Semiconductors: Uses & Parts
Current flows through electronic circuits. Learn about the parts of a circuit and how circuits are built around circuit boards. Also, discover how semiconductors showed us the path to the small, but powerful integrated circuits of modern electronics.
2. History of Computers: Timeline & Evolution
Modern computing has a rich history. Learn about the earliest computing devices developed by humans, the first electronic computers and the development of modern computer components, such as microprocessors and the graphical user interface, in this video lesson.
3. 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).
4. 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.
5. Computer Operating Systems: Managing Hardware and Software Resources
This lesson will introduce you to computer operating systems and help you figure out the difference between application and operating system software. Also, we will learn the difference between a desktop and wallpaper.
6. Application Software for Personal, Enterprise & Workgroup Objectives
Application software is a computer program to carry out a specific task. Learn about the different types of applications at the individual, workgroup and enterprise level.
7. World Wide Web: How the Web Works
In this lesson, an overview of the World Wide Web is discussed, including its development and operation. The various technologies that enable the Web to work are also described. Topics include Web browsers, hypertext markup language, hypertext transfer protocol, hyperlink and FTP.
