What is the process ID of init process?

What is process ID in Linux?
The process identifier (process ID or PID) is a number used by Linux or Unix operating system kernels. It is used to uniquely identify an active process.
How much RAM do I have Linux?
To see the total amount of physical RAM installed, you can run sudo lshw -c memory which will show you each individual bank of RAM you have installed, as well as the total size for the System Memory. This will likely presented as GiB value, which you can again multiply by 1024 to get the MiB value.
