Study Notes
Operating System Overview
- An operating system (OS) is software that manages computer hardware and software resources
- OS provides essential services for users and applications
- OS allocates resources like CPU time, memory, storage, and input/output devices
- OS manages process creation, scheduling, and termination, ensuring smooth multi-program execution
- OS manages computer memory (RAM), allocating and freeing space as needed
- OS manages data storage using a file system, allowing users to save, retrieve, and organize files
- OS manages communication between the computer and peripheral devices (printers, scanners, external drives)
User Interface
- OS provides user interfaces (GUI or CLI) for user interaction
- GUI (Graphical User Interface) allows users interaction through graphical elements (icons, windows, menus)
- CLI (Command Line Interface) allows users interaction by typing commands
- Common icons (files, folders) represent documents and directories
- Application icons are shortcuts to programs with logos to quickly recognize them
- System icons provide quick access to key settings (Wi-Fi, volume, battery)
- Menus provide structured access to application features and tools
Menu Interactions
- Drop-down menus: Accessible by clicking main menu items, showing related actions
- Pop-up menus (context menus): Appear upon right-clicking objects, offering context-specific options
- Menu selection involves clicking options to choose actions
- Menus are helpful for navigation and efficient task completion, using methods like: clicking a mouse, touch input, keyboard shortcuts, or gestures
Window Management
- Windows are used to run applications
- Windows can be minimized, maximized, closed
- Windows can be resized and moved by dragging their title bars
- Shortcuts link to applications or files for quick access
- Using shortcuts allows frequently used items access without additional searches
- Shortcuts can be created on Windows or macOS
Operating System Functions Summary
- Resource Management: Allocates CPU, memory, and devices to applications; manages processes for smooth multitasking
- File and Memory Control: Organizes memory use and file storage
- User Interface: Provides GUI or CLI for user interaction
- Shortcuts and menus: Simplifies access to files and applications
End-of-Session Questions
- Role of OS in resource management
- Processes management by the OS for smooth execution
- Difference between GUI and CLI, including user-friendliness
- Memory management by the OS and its importance
- Benefits of creating shortcuts for frequently used application files
