Study Notes
Computer Software: Classification
- Software is categorized into Application and System software
- Application software is further divided into Information Worker, Entertainment, and Education software.
- System software includes Operating Systems, Device Drivers, and Utility Tools.
Application Software (User)
- Also known as User Applications
- Designed for specific user functions, not for managing the computer.
- Examples include:
- Information Worker: Microsoft Office (Word, Excel, PowerPoint), PDF applications, Document Management
- Entertainment: Music Players, Video Players, Gaming
- Education: Subject-specific software (e.g., MathLab), Learning Management Systems (LMS)
- Enterprise Infrastructure Software includes tools like ERP (Enterprise Resource Planning), Accounting, and Financial Systems.
- Other examples include Simulation Software (e.g., Motion Modeling, Workflow Modeling), Media Development Software (e.g., Audio/Video editing), Product Engineering Software (e.g., AutoCAD), and Software Engineering tools (e.g., IDEs like Eclipse).
System Software
- Controls the overall operation of a computer
- Provides means for users to store, retrieve and execute programs
- Includes Operating Systems, Device Drivers, and Utility Tools
Operating Systems
- Manages the computer's resources (memory, processes, etc.)
- Manages the boot-up and shutdown process.
- Manages System Memory and other System Resources
- Manages Scheduling
- Manages Application Management and Process Administration
- Includes the Kernel and User Interface.
Device Drivers
- Written by hardware manufacturers
- Enable the operating system to interact with the hardware
- Specific set of instructions
Utility Tools
- Designed for user control and management of specific parts of the computer system
- For example, managing or maintaining the computer
Firmware
- Low-level control software embedded within hardware
- Usually stored permanently in ROM (Read-Only Memory)
Operating Systems (Details)
-
Primary Responsibilities :
- Managing boot-up and shut-down processes
- Managing system memory and other system resources
- Scheduling tasks and processes
- Application management
- Process administration
-
Booting process :
- Machine starts, boot loader program is executed
- Operating system is loaded into memory
- Control is transferred to the operating system
-
Interrupt Handling :
- System responds to external events (e.g., keyboard input, mouse clicks)
- Processes are switched between by the Kernel
- Advancing time with time slices is managed efficiently.
-
Deadlock Handling:
- Scenarios where processes are blocked, unable to proceed.
- System mechanisms must handle and prevent potential deadlocks effectively
Operating Systems examples
- Server Operating Systems (e.g., Windows, Linux)
- PC Operating Systems (e.g., Windows, Linux)
- Apple Operating Systems (e.g., Mac OS X)
