Study Notes
Operating System Fundamentals
- The operating system (OS) is responsible for the computer’s hardware management.
- The OS makes it possible for application software to work with the central processing unit (CPU).
- The OS can also manage, schedule, and coordinate various computer tasks.
Understanding System Software
- The top three operating systems for personal computers are Windows, macOS, and Linux.
- Mobile operating systems include Android, iOS, and Windows.
- The OS category can be single or multi-user, in addition to being single or multi-task.
Operating Systems for Machinery, Networks, and Business
- A real-time operating system (RTOS) is used for machines performing repetitive tasks at specific time intervals.
- A multi-user operating system, also known as a network OS, allows multiple users to access the computer simultaneously.
- Unix is an example of such an operating system.
What the Operating System Does
- The operating system provides the user interface which allows for interaction with the computer.
- There are three types of interfaces: command-driven, menu-driven, and graphical user interface (GUI).
- An interrupt handler triggers an event in the computer system.
- The OS uses preemptive multitasking to juggle multiple programs at once.
- A spooler temporarily holds output until the device becomes available.
Hardware Coordination
- The OS manages both memory (RAM) and storage.
- Virtual memory uses space on the drive to extend RAM capabilities.
- Increasing the amount of RAM reduces reliance on virtual memory.
- A swap file stores data being swapped between RAM and the hard drive.
- Paging is the process of moving data between RAM and storage in page-sized chunks.
- Thrashing is excessive swapping between RAM and storage, leading to system slowdown.
- Device drivers allow the OS to communicate with hardware, including peripherals.
- Plug and Play (PnP) automatically configures new hardware components.
- Rollback allows for reverting to a previous state of a device driver.
Software Application Coordination
- The operating system utilizes an application programming interface (API) to communicate with application software.
- The API consists of blocks of code that the CPU recognizes and employs for similar procedures.
- An example of an API is Microsoft Direct X for gaming applications.
Starting Your Computer
- The boot process consists of four steps: powering on, performing the Power-On Self-Test (POST), loading the bootloader, and loading the operating system.
- The Basic Input/Output System (BIOS) handles data exchange between the OS and input/output devices.
- The BIOS loads the OS into RAM.
- The POST ensures essential peripheral devices are connected and functioning correctly.
- The OS system files are loaded into RAM.
- The kernel, the core of the OS, is then loaded.
- The registry stores configurations used by the OS and applications.
The Windows Interface
- The Windows desktop serves as the primary workspace.
- The taskbar displays open and favorite applications.
- The Start menu provides access to all installed applications and apps.
- Pinning allows for selecting specific applications to appear as tiles in the Start menu.
- Virtual desktops enable users to organize groups of windows into different displays.
User Interfaces for Other OSs
- macOS and Windows interfaces are not compatible but offer similar functionalities.
- Linux interfaces are often based on familiar Windows and macOS designs.
File Management
- The file system utilizes a hierarchical structure to organize computer contents.
- This structure includes drives, libraries, folders, subfolders, and files..
- The root directory (C:) represents the top of the filing structure.
- A file is a program instruction or data treated as a single unit stored on a permanent storage device.
- A folder is a collection of files.
- A file path is a sequence of directories that lead to a specific file.
- Windows uses a backslash (), Linux uses a forward slash (/), and macOS uses a colon (:).
- File Explorer is the primary tool for finding, viewing, and managing computer contents.
- It displays the location and contents of every drive, folder, and file.
- File names contain the actual name and an extension that indicates the file type.
- File management includes actions such as opening, copying, cutting, renaming, deleting, and using the Recycle Bin.
- A file compression utility reduces file size, making it easier and faster to send and store.
System Productivity, Backup, and Accessibility Tools
- File compression is a valuable tool for shrinking file sizes.
- Backup utilities create copies of important data to protect against loss.
- Accessibility features provide accommodations for users with disabilities.
- The OS offers tools and features to enhance system productivity, back up files, and provide accessibility.
