Which command will you use to display history of OS?
Answer: B) Ver
In MS-DOS, the VER command is used to display the operating system's version information. It shows which version of DOS is currently running.
Example:
VER
Output:
MS-DOS Version 6.22
Other options:
- DATE: Displays or changes the system date.
- VER: Displays the DOS version.
- DISPLAY: Not a standard MS-DOS command for showing OS version history.
- FORMAT: Formats a disk.
MS-DOS मा VER कमाण्डले हाल कम्प्युटरमा चलिरहेको Operating System को Version जानकारी देखाउँछ।
उदाहरण:
VER
यसले MS-DOS को Version जस्तै 6.22 देखाउन सक्छ।
- DATE: System Date देखाउन वा परिवर्तन गर्न प्रयोग हुन्छ।
- VER: Operating System को Version देखाउँछ।
- DISPLAY: OS Version देखाउने Standard DOS Command होइन।
- FORMAT: Disk Format गर्न प्रयोग हुन्छ।
त्यसैले सही उत्तर B. VER हो।
Exam Tip: VER = Version of Operating System।
