    Ok, so in regards to Abstraction by specification, in relation to programming, that would be dividing up a program so that you can work on the parts individually? It's simplification by working on specific parts of a problem you are using a program to solve it? That way you can allow better troubleshooting if issues come up, and if you want to add to parts its simpler because you have the program already divided into parts?

    A philosophy major can talk about chairs and black holes all they want, but I ask for a real world example of someone experienced in computer science and now there is something wrong with me. I like your logic sir.

    So just to reiterate, to see if I'm grasping this properly, abstraction is simplification by removal of any unnecessary parts. Abstraction by parameterization means simplification via placeholders or categorization - any way you can group several components into lesser amounts of components. For example, instead of writing code for each of 100 individual squares to be drawn, you might write a for loop to draw them all and save yourself a bunch of code?

    Could you give me a real world example of when you ever need to describe something that way? I think this is all very difficult for me because I've read very many definitions of abstraction by specification and they all seem to be worded much differently than each other. It's like there's no standard definition, and all of them are hard to understand, are there no examples of its use in a sentence and/or with any particular set of code. I mean there probably are simple definitions with nice examples, but I haven't found any yet.

    So what's the point of saying abstraction by parameterization when you could just say 'using a variable' or 'using a string'? It just seems like extra syllables for no reason.

    So abstraction is just using parameters that are placeholders for information that would take up more space than just the placeholder? Is it considered abstraction when there is no data? or just in instances where there is? So say I have a string or variable but it contains no info - that's not abstraction by parameterization because there is nothing to abstract from?
