Study Notes

Operating System Functions

Manages the computer's hardware.
Allows application software to work with the CPU.
Manages, schedules, and coordinates tasks.

User Interface

The way a user interacts with a computer.
Examples include desktops, icons, and menus.

Operating System Categories

Single or multi-user
Single or multi-task

Popular Operating Systems for Personal Use

Windows
macOS
Linux
Android
iOS

Real-Time Operating System (RTOS) manages specific tasks precisely, while Multiuser Operating System (Network OS) supports simultaneous user access, e.g., Unix.

The User Interface

Command-driven interface: Users enter commands to perform actions.
Menu-driven interface: Users select from lists of options.
Graphical user interface (GUI): Users interact through visual elements like icons and windows.

Hardware Coordination

Event: An action that requires the OS to take notice.
Interrupt handler: The OS temporarily suspends what it is doing to deal with an event.
Preemptive multitasking: The OS divides processor time among multiple applications running.
Spooler: Handles sending jobs to devices like printers.

Managing Memory and Storage

The OS must manage the computer's limited RAM.
When RAM is full, the OS uses virtual memory, a technique for borrowing from the storage device.
A swap file is created to temporarily store data that does not fit in RAM.
Paging: The OS moves data between RAM and the swap file.
Thrashing: When the system spends too much time moving data between RAM and the swap file, it can significantly slow down the computer.

Managing Devices

Device driver: A program that allows the OS to communicate with a peripheral device.
Plug and Play (PnP): The OS automatically detects and configures new hardware.
Roll Back: Allows the user to restore the device to its previous state if necessary.

Software Application Coordination

Application Programming Interface (API): A set of pre-written code blocks used by the CPU to perform common tasks. These blocks are often shared by different programs, making development easier.

The Boot Process

Step 1: Power On: The computer receives initial power.
Step 2: POST (Power-On Self Test): Checks if essential parts like the CPU, memory, and peripherals are connected.
Step 3: Loading the Bootloader: This program initializes the hardware and prepares the system for the OS load.
Step 4: Loading the Operating System: The OS is loaded into RAM, including the kernel (essential part of the operating system).

Loading the OS

BIOS (Basic Input/Output System): It manages the communication between the OS and input/output devices. It plays a crucial role in loading the OS into RAM.

Windows Interface

Desktop: The primary work area.
Taskbar: Displays open and favorite applications for easy access.
Start Menu: Provides access to all applications and apps installed on the computer.

File Management

Directory: The hierarchical structure of the computer's contents. It includes:
- Drives
- Libraries
- Folders
- Subfolders
- Files
Root Directory (C:) The top of the filing structure.
File: A collection of program instructions or data treated as a single unit.
File Path: The location of a file within the directory structure. It indicates the steps to access it.

File Explorer

The primary tool for navigating, viewing, and managing files. It shows all drives, folders, and files.

File Compression Utilities

Used to make large files more compact. This makes the file easier and faster to send.
Many operating systems have built-in file compression.
