Reducing resource usage?

After rooting around the internet, I think I've finally found the right place. I was finding all kinds of resources for Jelly Bean but after looking at the topic options here, it looks as if I have KitKat. The Android build is 4.4.2. It looks as if anything 4.4 is KitKat. Is that right? It's not Jelly Bean after 4.3?

Just a little background on me and my tech skills. I started working with computers during the Trash80 years and was working with Microsoft products when it was still just DOS and you had to set up .sys and .ini files to get programs to work. I also had some knowledge of strings and threads.. However, as computers got easier to use with things like point-and-click, I got lazy and my knowledge of the intricacies of the technical end of stuff fell way behind. So, I have the potential to understand more technical details, I just have to decide to learn it.

So, I'm here to learn as much as I can. Currently I'm dealing with a high resource usage problem. I downloaded the Simple System Monitor app because I was getting the idea I was having a resource problem and it did confirm that I am. I uninstalled a lot of apps that I just don't use anymore and that the Simple System Monitor said was using resources at a rather high rate. However, my resource usage is still around 99% even though I'm not seeing that much usage in the apps. I'm guessing some sort of background processes are eating up resources but I don't know how to find them or what to do with them once I do. I have apps that this phone does not give me the option to uninstall - all sorts of stuff that came with the phone but that I consider bloatware; totally useless to me.

I've run MalwareBytes and it does not find any malware so, I'm not entirely sure what is going on and could use any input available to figure out what is going on here.

I'd love to learn more about this operating system so, if anyone knows of any place I can go for tutorials beginner to advanced, I'd appreciate it.

Thanks in advance for any help here,

What exactly is reporting 99% "resource usage"? That's not typical terminology in the native Android settings menu. Are you talking about system RAM? If so, remember that Android is designed to keep RAM relatively full of opened apps (usually up to 70-80% or so), which allows them to be accessed more quickly when the user needs them. If the user opens an app that isn't already residing in RAM, and if some RAM has to be cleared in order for the new app to open, then the system automatically decides which app to close.

3rd party "RAM cleaner" or "memory booster" apps typically do nothing to help performance, and often worsen it, along with increasing battery usage. I've also seen system monitor apps increase RAM usage themselves, just by being actively used.
