About This Chapter
Introduction to Operating Systems - Chapter Summary
This comprehensive computer science chapter helps you quickly learn the fundamentals of operating systems. Using a simplified and engaging teaching style, our instructors show you basic concepts related to operating system functions, history, structures and types. You'll also learn how to set up a coding environment. You can complete the chapter at your own pace using any computer or mobile device. We've included plenty of self-assessments throughout the chapter to help you retain the information. By the end of the chapter, you should be able to:
- Evaluate several operating system functions, including security, system management, communication and hardware/software services
- Summarize the history of operating systems
- Explain how operating systems help manage hardware and software resources
- Assess command line interface parameters and options
- Talk about the computer booting process
- Describe the structure of layered operating systems
- Assess the differences between 32-bit and 64-bit operating systems
- Differentiate between enterprise, personal and workgroup operating systems
- Set up a coding environment
- Discuss the benefits of virtualization
1. 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.
2. History of Operating Systems: Timeline & Evolution
Have you ever been amazed at the magic taking place inside your computer or smartphone? Your device's operating system does a lot behind the scenes to display images and text, play audio, print, and do so much more.
3. 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.
4. Command Line Interface: Commands, Parameters & Options
Despite the popularity of graphical user interfaces, command line is still widely used. In a command-line interface, a user interacts with a computer by typing in lines of text. Learn about the use of commands, parameters and options.
5. Booting a Computer: Definition & Process
In this lesson, we will learn what 'booting' a computer means, where the term comes from, and what happens exactly during the boot process. We will also explore why you may need to start your computer in safe mode.
6. Layered Operating System: Architecture, Approach & Structure
In a world where devices are getting smaller and smarter, it makes sense that we should have something to control them. In this lesson, we'll take a look at one possibility, layered operating systems.
7. 32-Bit & 64-Bit Operating Systems: Differences, Identification & Examples
This lesson will introduce you to the concept of 32-bit and 64-bit architecture of operating systems. We will discuss evolution and differences between these architectures and look at few examples of operating systems.
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. How to Set up a Coding Environment for Computer Science 305
In this practical lesson, you will be setting up an environment for coding in the Computer Science 305 course. We will be installing GCC (GNU Compiler Collection) in a Windows environment.
10. Virtualization: Definition & Benefits
Virtualization is a hot topic these days, particularly in business. In this lesson, we'll take a look at virtualization, including what it is and some benefits of using it.
