SysStats Lite shows you all the major processes and lets you close the ones that can be stopped without affecting the whole system. Raising your hand to your nose, putting your fingernail on the spot that itches, scraping the the skin just so until the itching stops are all processes which can be broken down into smaller processes. Processes are the activities required to accomplish the task. We can call that task the NoseScratch app. Think of it this way: lets say you want to scratch your nose. Processes are not apps, but the code being executed by apps and the OS to make the whole system run. The second screen shows the processes that are currently running or are waiting in queue to run whenever you need them. It's all laid out logically and is very easy to read and not difficult to understand, and it's the screen you'll check most.
The first shows hardware activity, memory usage, CPU stats, battery level. SysStats Lite puts hardware info all on one screen The interface has changed over the years, but it remains one the best system monitoring apps available. If you have to know what your phone is thinking about you'll want to know it in plain english. If you could find a way to call up a command line, looking at all of the cryptic numbers dance and flicker on your screen is enjoyable for only so long. Today such details are lost on most folks, but it does help sometimes to know how that computer in your pocket is doing. They had scripts that could show which process or sub-process was doing what and when. One of the things deep geeks did from the command line was monitor system activity. It's testament to how versatile the OS is. True, it's been striped to its most needed unmentionables, but it's still UNIX at heart. I'd bet most iPhone owners don't realize (or care) that the same OS that can handle millions of bank or airline transactions an hour is the same OS that lets their iPhone play Angry Birds. The bigger your cache, the deeper you geek status. Each deep geek had his own cache of scripts that did everything from text formatting to playing tic tac toe.
They were true magicians and they worked their magic on what I consider to be the most robust computing environment yet. These guys could write a bit of code and have a room full of UNIX servers doing the digital version of the merengue. Their magic discipline of choice was UNIX using Korn, Bourne, or C shell command line interpreters. There were guys who understood the terrain far better than I did.
I wrote arcane command line scripts that did fun things like parse lists of names for certain parameters and pipe them to another list that might be used for mailing or whatever.
There was a time when I was chest high into deep geek doings.
