MSD.exe does not have information on:

  1. Cache

  2. Video

  3. Operating System

  4. Com or port


Correct Option: A

AI Explanation

To answer this question, we need to understand what MSD.exe is and what type of information it provides.

MSD.exe is a command-line tool in Windows that stands for Microsoft System Diagnostics. It provides detailed information about the hardware and software configuration of a computer system. When you run MSD.exe, it generates a report that includes information about various system components.

Let's go through each option to understand why it is correct or incorrect:

Option A) Cache - This option is correct because MSD.exe does not provide information specifically about the cache. The cache is a hardware component that temporarily stores data to improve system performance. While MSD.exe provides information about other hardware components like the CPU, memory, and storage, it does not include details about the cache.

Option B) Video - This option is incorrect because MSD.exe does provide information about the video or graphics card. The report generated by MSD.exe includes details about the installed video card, display resolution, and other video-related information.

Option C) Operating System - This option is incorrect because MSD.exe does provide information about the operating system. The report generated by MSD.exe includes details about the installed version of Windows, system files, and other operating system-related information.

Option D) COM or Port - This option is incorrect because MSD.exe does provide information about COM ports. The report generated by MSD.exe includes details about the available COM ports on the system and their configurations.

Therefore, the correct answer is A) Cache. MSD.exe does not have information on the cache.
