How can memory usage be checked in DOS?

• A. Using the "CHECKMEM" command
• B. By executing the "MEM" command
• C. With the command "SHOWMEMORY"
• D. Through the "SYSTEMINFO" command

Answer: (B)

In DOS, the most direct way to check memory usage is by executing the "MEM" command. This command provides a detailed report on the amount of conventional memory, upper memory, and expanded memory that is being utilized. It displays how much memory is free and how much is used by various programs and the operating system, allowing users to get a clear overview of memory status. This command is essential for diagnosing memory-related issues and optimizing the performance of a DOS system. By using the "MEM" command, users can identify how their resources are allocated and make necessary adjustments based on their system's performance needs. Other commands, while they may relate to system information or memory indirectly, do not provide the same level of specific details about memory usage as the "MEM" command does.
