Which of the following options is not a utility system?
A. Virus scanner
B. System profiler
C. Disk defragmenter
D. Debugger
The correct answer and explanation is :
The correct answer is D. Debugger.
Explanation:
Utility systems are programs designed to perform specific maintenance tasks or manage the functioning of the computer system, often related to system optimization, security, or troubleshooting. The listed options can be categorized into utility and non-utility tools based on their primary function.
- A. Virus Scanner:
- A virus scanner is a utility program designed to detect and remove malicious software (viruses, worms, spyware) from a system. It scans files and programs for known threats and helps keep the system secure. As part of system maintenance, it is a crucial tool to prevent damage caused by malware, making it a utility system.
- B. System Profiler:
- A system profiler is a utility that provides detailed information about the hardware and software configuration of a system. It can give users insights into their system’s CPU, RAM, storage, and other components. This helps in troubleshooting, upgrading hardware, and understanding the system’s capabilities, making it a utility system.
- C. Disk Defragmenter:
- A disk defragmenter is a utility that helps optimize disk performance by reorganizing fragmented data. When files are stored and deleted repeatedly, they can become fragmented, leading to slower access times. The defragmenter reorganizes these files so that they are stored contiguously, thus improving system performance. This is another essential utility tool.
- D. Debugger:
- A debugger is a software tool used by developers to identify and fix bugs or errors in programs or applications. It is primarily used during the development process to test and troubleshoot code. While debugging tools are essential for software development, they are not typically considered part of system utilities because they are specifically targeted at development and debugging software, not directly maintaining or optimizing the operating system.
Conclusion:
A debugger (D) is not a utility system, as it is primarily used for software development and debugging, not for maintaining or optimizing the system.
