CSET Business Subtest III: Computer Technology - Chapter Summary
The lessons in this chapter introduce you to computer components, operating systems, and functions. Use these lessons to expand your knowledge of subjects you'll need to know for the CSET Business Subtest III. The videos cover:
- Binary, digital, and analog representation of data
- Components of information processing systems
- Computer input and output devices (audio, video, etc.)
- Enterprise, workgroup, and personal operating systems
- Functions of computer system components
- Information system resources
- Memory storage types and processing devices
- Operating system functions
Using examples you can relate to, the videos in the computer technology chapter help you understand and remember topics such as those that come up on the CSET Business Subtest III.
CSET Business - Computer Technology: Objectives
The CSET Business exam tests your ability to meet basic skill requirements, competence, and knowledge of the subject in preparation for California teacher licensing in business. The CSET Business Subtest III makes up a third of the CSET Business exam. For this subtest, you'll need:
- A working knowledge of common computer terminology and concepts
- An understanding of how to evaluate, install, and configure computer components, operating systems, software, and peripherals
- Understanding of how to use operating systems and memory storage and recovery systems
- Knowledge of basic troubleshooting procedures
- An understanding of the impact of computer technology on society
The CSET Business Subtest III consists of 40 multiple-choice questions. Of these, 15 cover business environment and communication, while 25 cover information technology. This chapter's video lessons each include a quiz to help you practice answering questions similar to the multiple-choice questions on the exam.
Subtest III also includes two constructed-response questions, which require you to analyze, interpret, discuss, or otherwise respond to an introductory paragraph, map, quotation, example situation, or other such resource. One constructed-response question on the subtest is short and focused; the other one requires an extended response. Reinforce your knowledge of computer technology with our video lessons so you feel confident going into the exam.
1. Information Systems Resources: Networks, Hardware, Software, Data & People
What are the resources an information system needs? Discover how networks, hardware, software, data and people work together to create usable information.
2. Input, Processing, Output & Feedback: Information System Components
What are the components that really make an information system work? In this lesson, we'll explore IPOS (input, process, output and storage) and how this system works.
3. 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.
4. 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).
5. 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.
6. 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.
7. 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.
8. Enterprise, Workgroup & Personal Operating Systems
While every computer needs an operating system, different devices and different users need different functionalities. Learn about the different types of operating systems.
9. 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.
10. OS Functions: Security, System Management, Communication and Hardware & Software Services
The operating system (or OS ) is the brain of a computer and manages its functions, including systems management/monitoring, communication/networking services management, security services management, and hardware/software services management.
11. 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.
12. Cache Memory: Definition & Concept
Cache memory is a type of memory used to hold frequently used data. Cache memory is relatively small, but very fast. Most web browsers use a cache to load regularly viewed webpages fast. The most important type of cache memory is the CPU cache.
