information, Memory (RAM) information stored under /proc
directory

particular hardware)
# cat /proc/meminfo (show the information of Memory i.e.
RAM of that particular hardware)

Answer / sahil makkar

Information related to process is stored in /proc
filesystem. One can say that full PCB(Process Control
Block) is there in /proc. proc is file system for RAM. Proc
filesystem is created while booting and as we run more
processes more entries are added to /proc directory for the
respective process.

Answer / sandeep b

Proc is a psuedo file system so nothing is actually stored.
A read results in a call to function inside the kernel which
provides the information we see.
It makes information about the kernel and hardware available
to the user.
