How to install cups server on Linux | How to Add Printer to CUPS Server ...

CUPS is a modular printing system for Linux/UNIX-Like computer operating systems which allows a computer to act as a print server. A computer running CUPS is a host that can accept print jobs from client computers, process them, and send them to the appropriate printer.



CUPS consists of a print spooler and scheduler, a filter system that converts the print data to a format that the printer will understand, and a backend system that sends this data to the print device. CUPS uses the Internet Printing Protocol (IPP) as the basis for managing print jobs and queues.

Linux System Load Average | Understand Load Average from command output ...



# cat /proc/loadavg



The first three fields in this file are load average figures giving the number of jobs in  the run  queue  (state  R)  or  waiting for disk I/O (state D) averaged over 1, 5, and 15 minutes. They are the same as the load average numbers given by  uptime(1)  and  other  programs.   The fourth field consists of two numbers separated by a slash (/).  The first of these is the number of currently runnable kernel scheduling entities (processes, threads).   The  value  after the slash is the number of kernel scheduling entities that currently exist on the system.  The fifth field is the PID of the process that was most recently created on the system.
