Question

Quizplus · Accepted Answer

The /proc file system is a pseudo-file system that provides command-line reporting and control information system in CentOS 7 that directly interfaces with the kernel and is stored in memory. It contains information about system resources, including process information identified by their PID. The ps command and PID are related to process information, but the /proc file system provides a more comprehensive view. The uptime command shows the system's uptime, whereas the vmstat command shows system statistics including CPU, memory, and disk usage. The watch free command provides real-time updates on memory usage. The kill command is used to terminate a process, and a bottleneck is a point of congestion in the system that slows down performance.
