Study Notes
Overview of Software
- Software is a computer program offering instructions to execute user commands and direction to the computer.
- Examples include MS Word, MS Excel, and PowerPoint.
- Software is classified into System Software and Application Software.
System Software
- Acts as an interface between the hardware and user applications, managing hardware components.
Types of System Software
-
Operating Systems (OS):
- Manages computer hardware and software resources, providing common services.
- Examples: Windows, macOS, Linux, Unix, Android, iOS.
- Functions include process, memory, file system, device management, and user interface.
-
Device Drivers:
- Programs that control specific hardware devices attached to the computer.
- Examples: Printer drivers, graphics drivers, network drivers.
- Enables communication between OS and hardware, ensuring proper function.
-
Firmware:
- Low-level software programmed into read-only memory for device control.
- Examples: BIOS, UEFI, firmware in embedded systems.
- Initializes hardware components and supports higher-level software.
Application Software
- Designed for users to perform specific tasks, ranging from productivity to entertainment.
Types of Application Software
-
Productivity Software:
- Aimed at increasing productivity, such as document, presentation, and spreadsheet management.
- Examples: Microsoft Office (Word, Excel, PowerPoint), Google Workspace.
- Functions: Creating, editing, and managing office-related tasks.
-
Multimedia Software:
- Applications for creating and managing multimedia content.
- Examples: Adobe Creative Suite (Photoshop, Illustrator), VLC Media Player, iTunes.
- Functions: Creating, editing, and playing audio, video, and graphics.
-
Web Browsers:
- Software for accessing and navigating the internet.
- Examples: Google Chrome, Mozilla Firefox, Microsoft Edge, Safari.
- Functions: Browsing web pages, downloading files, running web applications.
Differences Between System Software and Application Software
- System software manages system resources, while application software performs specific user tasks.
- System software generally installed with the OS; application software installed as needed.
- System software operates independently; application software depends on system software.
- System software is typically written in low-level languages; application software in high-level languages.
Booting Process
-
Power-On Self Test (POST):
- Initial diagnostic check on hardware components to ensure functionality and presence.
- Tests components like CPU, RAM, and storage devices.
- Displays error messages or beep patterns in case of failures.
-
BIOS:
- Firmware on the motherboard providing initial instructions during boot.
- Initializes hardware components like the video card, keyboard, and storage drives.
-
Loading the Operating System:
- Bootloader: Program that initiates the operating system loading process by transferring control from BIOS.
- Kernel Loading: The core part of the OS, it loads into memory and takes control system operations.
-
System Configuration:
- Kernel initializes hardware and sets up memory management.
- Loads necessary drivers and mounts the root filesystem.
-
Loading System Utilities:
- Runs initialization scripts to configure the system and start services.
- Services include network management and system logging.
-
User Authentication:
- Login prompt appears, asking for credentials either in CLI or GUI format.
- System verifies user credentials and may perform additional security checks.
File Management in Operating Systems
- Processes involved in creating, organizing, and controlling files on storage devices.
- Key activities: creation, deletion, naming, classification, and protection of files.
- Involves metadata management such as file name, size, creation date, permissions, ownership, and type.
Key Components of File System Management
-
File System Structure:
- Files as storage units; directories to hold files and organize them hierarchically.
- Paths indicate the route to access files or directories.
-
File Types:
- Regular files containing user data, directories for organizing files, special files for device I/O, and links serving as shortcuts to other files.
