The correct choice provides access to detailed information about the system's RAM. The file located at /proc/meminfo contains a variety of data related to memory usage, including total RAM, free RAM, buffered and cached memory, and other memory-related statistics. This information is crucial for system monitoring and troubleshooting, as it offers real-time insights into how memory is being utilized by the Linux operating system.
The /proc directory is a virtual filesystem that provides a dynamic view into the kernel's data structures, making it an ideal source for obtaining system information. Specifically, /proc/meminfo is continuously updated by the kernel, ensuring that users have access to the most current statistics regarding memory usage on the system.
In contrast, the other options either do not exist or do not provide the same level of detail about RAM. For instance, /proc/stat offers information on CPU usage and system load rather than memory specifics. /etc/meminfo is not a standard file that provides memory information, and /var/log/meminfo does not typically exist in a default installation of Linux, making it an unreliable option for accessing RAM details.
