Short Answer Questions:
Define system software and provide two examples.
System software is a type of computer software designed to run and manage the hardware and basic system operations of a computer. It acts as a bridge between the computer hardware and application software, ensuring all components work together effectively. The software used to control, monitor or facilitate the use of computer is called “System Software”.
Examples:
- Operating System
- Device Drivers
Explain the primary functions of an Operating System.
The following tasks can be considered as the primary functions of an Operating System:
- Manages hardware resources
- Load and execute programs
- Detect hardware failures
- Display message to fix hardware failure issues
- Controls the operations of input/output and storage devices.
What is Utility software and why is it important?
Utility software: Utility software is a type of system software designed to help manage, maintain, and optimize a computer’s performance. It provides tools that perform specific tasks to keep the system running smoothly and efficiently.
Importance:
- Improve System Performance
- Enhances Security
- Prevents Data Loss
- Maintains System Health
- Supports System Efficiency
Describe the role of Device Drivers in a computer system?
Device Drivers: Device drivers are system software. They play a critical role in a computer system by acting as a translator between hardware devices and the operating system. Without drivers, the operating system would not be able to communicate with hardware components effectively. When a user attaches a device such as printer or scanner to their computer, they should install their driver also to make it operational. Device drivers are provided by device manufacturers.
Differentiate between system software and application software with examples.
System Software vs Application Software
| System Software | Application Software |
|---|---|
| Runs the computer and controls hardware. | Help you do specific tasks on the computer. |
| Works in the background. | Used directly by the user. |
| System software makes the computer work. | Application software helps you do work on the computer. |
| Example: Windows, macOS, Android | Example: MS Word, Chrome, PowerPoint |
