Can you recommend any programming resources or glossaries to explain computer science jargon and terminology for Newbies / Laymen?

Start small, friend. You can't expect to understand any advanced technology all at once. Computer programming just happens to be the most accessible of technologies. I hope, here, you have some knowledge of programming. If not, I'll direct you to courses on https://www.khanacademy.org/cs/tutorials/programming-basics or elsewhere to understand basic terms like variables, functions, etc. Once you do that, come back to OOP. Here's how I do my learning, whatever the field be: Reading Object-oriented programming (OOP) is a programming paradigm that represents concepts as "objects" that have data fields (attributes that describe the object) and associated proceduresknown as methods. Objects, which are usually instances of classes, are used to interact with one another to design applications and computer programs.” Ok, I'm here looking for OOP. Now comes the terms programming paradigm. It looks like some group to which OOP belongs. Who cares about the group? For now, I'll focus on OOP, and consider the term "programming paradigm" as a black box, whose internals I'll check later. Okay, now comes objects. Clearly OOP sees things as "objects". What are objects? Reading on, it contains "data fields and procedures (known as methods)". Woah. Now we come to the core, and here I'll look up what data fields are and what procedures are. Methods are just a label for procedures, for now. Now, it says Data fields. So they must be variables. Move on.  Now, I look up procedures: http://en.wikipedia.org/wiki/Procedure. Hey! The last line says procedures are also known as functions, which I already know about. So when functions go inside objects, they are called methods! If there's anything more to that, I'll think about it later. Now, in the next line comes classes. I scan through the https://en.wikipedia.org/wiki/Class_(computer_science) page and see blah blah blah.. technical gibberish... blah blah blah... Classes define the https://en.wikipedia.org/wiki/Data_type of their instances. Yes! From what I know of variables, I can see classes are something like int, double, string, and objects are the variables of those types. If there's anything more, I'll see about that later. So far, here's what I understand: objects are variables containing more variables and even functions! And that is what an object means in a nutshell. So the mythical resource that you are looking for is yourself. When you find yourself overloaded with jargon, step back, focus on a few terms that seem relevant to you. Once you have those terms down, look code examples of those things and then proceed to advanced code examples before going back to the jargon. Once I have enough practice creating classes and objects, I'll go back to the definitions of class and methods to see if there are any nuances I need to know, and if I understand the definitions better. In this case, once I have a good enough understanding of OOP to see how to apply it to problems, then I'll go back to see what a programming paradigm is and then see if there are any others in that group I should know of. The key question: before I start coding, is it essential that I understand what this term means? I dunno. How do I find out? Only one way: start coding. Just a short list of terms that you don't need to bother yourself with right now: compiler, interpreter, imperative, declarative,          -paradigm,         -typed... tl;dr: If I see too much jargon, I'll consider some of the terms to be http://en.wikipedia.org/wiki/Black_box (that page is itself full of gibberish - essentially, I don't understand what this thing really is, but for now I'll take it for granted and come back later). The key point is that you do come back later. Side note: This is especially useful in college - if you miss some lectures, in the next ones you attend, note down any terms mentioned that you don't understand as http://en.wikipedia.org/wiki/Black_box, and look them up later.
