			In "top" what are us, sy, ni, id, wa, hi, si and st (for CPU usage)?

			'''us''' - user cpu time (or) % CPU time spent in user space

			'''sy''' - system cpu time (or) % CPU time spent in kernel space

			'''ni''' - user nice cpu time (or) % CPU time spent on low priority processes

			'''id''' - idle cpu time (or) % CPU time spent idle

			'''wa''' - io wait cpu time (or) % CPU time spent in wait (on disk)

			'''hi''' - hardware irq (or) % CPU time spent servicing/handling hardware interrupts

			'''si''' - software irq (or) % CPU time spent servicing/handling software interrupts

			'''st''' - steal time % CPU time in involuntary wait by virtual cpu while hypervisor is servicing another processor (or) % CPU time stolen from a virtual machine

			== '''Process table''' ==
			The column headings in the process list are as follows:

			'''PID''': Process ID.

			'''USER''': The owner of the process.

			'''PR''': Process priority.

			Resident memory, labelled RES: How much physical memory, how much RAM, your process is using. RES is the important number.

			'''SHR''': Amount of shared memory used by the process.

			'''S''': Status of the process. (See the list below for the values this field can take).

			'''%CPU''': The share of CPU time used by the process since the last update.

			'''%MEM''': The share of physical memory used.

			'''TIME+''': Total CPU time used by the task in hundredths of a second.

			'''COMMAND''': The command name or command line (name + options).
