Which one is not a system tool?
Answer: C) Virus scanning
Backup and Disk Defragmenter are traditional system utility tools used for data protection and disk maintenance. Virus scanning is generally associated with antivirus or security software, so in this traditional computer-fundamentals MCQ, Virus scanning is the expected answer.
Backup: Creates copies of files to prevent data loss.
Disk Defragmenter: Organizes fragmented data on a hard disk.
Virus Scanning: Detects and helps remove computer viruses.
Backup र Disk Defragmenter परम्परागत Operating System मा प्रयोग हुने system utility tools हुन्। Backup ले डाटाको प्रतिलिपि बनाउँछ भने Disk Defragmenter ले हार्ड डिस्कमा छरिएर रहेका डाटालाई व्यवस्थित गर्छ। Virus scanning भने सामान्यतया antivirus वा security software अन्तर्गत पर्छ। त्यसैले यस MCQ को अपेक्षित उत्तर C. Virus scanning हो।
Exam Tip: पुराना Computer Fundamentals MCQs मा Backup र Disk Defragmenter लाई system tools तथा Virus Scanning लाई security software को रूपमा छुट्याइएको पाइन्छ। तर आधुनिक Operating System मा virus scanning का सुविधाहरू पनि समावेश हुन सक्छन्।
