Study Notes

Technology in Action - Chapter 5

  • This chapter covers system software, specifically the operating system, utility programs, and file management.
  • The learning objectives outline key topics covered in the chapter, including the functions of the operating system, popular operating systems, different types of operating systems, user interaction with computers, hardware management by the operating system, operating system interaction with applications, the computer boot process, Windows interface features, file management tasks, and tools for productivity, backup, and accessibility.

Operating System Fundamentals

  • Operating systems (OS) manage computer hardware, allowing application software to interact with the central processing unit (CPU).
  • Utility programs are part of or separate from the OS offering additional functions like file compression or antivirus protection.
  • The OS schedules and coordinates tasks.
  • The user interface (UI) is how users interact with the computer, with notable types including command-driven, menu-driven, and graphical user interfaces (GUIs).

Understanding System Software - Operating Systems for Personal Use

  • Popular operating systems for personal use include Windows, macOS, iOS, Android, Linux, and Chrome OS.
  • Each system is developed by a different company or organization(s), and is tailored to specific devices(e.g., laptops, tablets, phones)
  • Linux is open-source software and has several distributions, offering customization options.

Understanding System Software - Operating Systems for Machinery, Networks, and Business

  • Real-time operating systems (RTOS) are optimized for repetitive tasks requiring precise timing.
  • Multiuser operating systems (network OS) enables multiple users to access the computer simultaneously.
  • Popular examples include Unix.

What the Operating System Does - User Interface

  • The operating system enables user interaction with the computer.
  • Types of interfaces include command-driven, menu-driven, and graphical user interfaces (GUIs).

What the Operating System Does - Hardware Coordination

  • The operating system manages computer hardware and peripheral devices effectively.
  • Event handling and interrupt handling allow the OS to coordinate actions between hardware elements.
  • Preemptive multitasking allows the operating system to switch between tasks rapidly.
  • Spooling allows offloading tasks and manages printers, while memory and storage management includes RAM-limited capacity, swap files, paging, and thrashing
  • Device drivers and plug and play (PnP) enable software to communicate with the device
  • Rollback is a mechanism for restoring to a previous state.

What the Operating System Does - Software Application Coordination

  • The Application Programming Interface (API) allows interactions between the operating system and applications.

Starting Your Computer — The Boot Process

  • The boot process involves four steps: powering on, performing the Power On Self Test (POST), loading the bootloader, and loading the operating system.
  • BIOS manages data exchange between the OS and input/output devices and loads the operating system into RAM.
  • The POST checks for essential peripheral device functionality.
  • The OS loads essential components like the kernel.
  • Configurations and customizations are stored in the registry for use by the operating system.

The Windows Interface - Using Windows 10

  • Windows 10 features a desktop as the primary working area, with a taskbar displaying open and favorite apps, and a Start menu for app access.
  • Common features available via Windows 10 include desktop pinning, virtual desktops for organizing windows, and file organization.

The Windows Interface - User Interfaces for Other OSs

  • macOS and Windows have similar functionalities; however, their user interfaces are not compatible with each other.
  • Linux user interfaces typically follow similar paradigms as Windows and macOS.

File Management - Organizing Your Files

  • File management involves hierarchical structures.
  • Directories, files, folders, and subfolders help users organize files.
  • File paths are used to locate specific files on the file system.
  • Using the Windows Explorer allows users to find, view, and manage computer contents.
  • File and directory organization allows effective file compression.

Utility Programs - Windows Administrative Utilities

  • Utility programs are incorporated into or are separate standalone tools that extend the operating system.
  • Essential utility programs to enhance OS functionality include firewall, file compression and antivirus programs, and freeware utilities.
  • System performance utilities, such as Disk Cleanup, Task Manager, and Disk Defragmenter enhance OS performance.
  • Backup utilities like File History and System Restore allow users to backup files for disaster recovery.
  • Accessibility utilities are designed for users with special needs, such as Magnifier, Narrator, Speech Recognition, On-Screen Keyboard, and High Contrast modes.
