What is Computer memory?

For some this may be a ridiculously easy question, for the beginner it is a mystery. Nevertheless I'll try to include just one or two facts with which you may not be familiar.
Ron King, in his lucid explanations for computer dummies, once more provides us with the facts.
However this time I don't think he has achieved the simplicity of the first of his posts that I mentioned.
He states Computer memory is RAM, Random Access Memory, but what of the stored hard disc memory, that does not seem to get a mention.
"RAM can be accessed randomly rather than sequentially", so what does that mean to the average person? Not a lot, I suspect. Although logic would support this contention and many would realise what he meant.
He then talks of the waiting time which other memories require as they follow their sequential requirements.
Now, a little more for the layman, "Computer memory is simply a storage area for the program code." I can understand that, but could a beginner?
Now he provides important information on how much memory is enough.
"As much as possible", but talks about diminishing return, which I can understand, others may not. I would have said "As much as possible, but, in reality, sufficient for the job"
How Much RAM is Enough?
He suggests 512 MB which seems pretty standard.
"Should you notice your computer slowing down, consider adding more memory. Before committing to that option, however, try de-fragmenting your hard drive with a utility (program) designed for that sole purpose. A fragmented hard drive is a common cause of stalled computer performance" Getting harder?
Now, is it DDR SDRAM, a decade ago SDRAM was standard.
"To add memory to your computer, you must install modules with the correct contact layout. Before purchasing new memory, you must know which type your motherboard will accept. The most common form factors are 168 pin, 184 pin and 200 pin".
Not for your average home user, I think.
"You'll also need to know whether there are slots available on your motherboard. If all the slots are already in use, you'll have to replace 1 or all of the current modules with higher capacity ones. If there is at least 1 free slot, you can simply buy a new memory module and insert it in the empty slot".
Last but not least, watch the electricals, is this a bit of a shock?
But Ron's article is informative and I hope there's at least some of you who think you're computer savvy who may now realise it's not as easy as you think.
I don't think I'll try what he suggests. Even 'tho I found what he had to say reasonably helpful and if I were game to try it, quite useful.
Here's his link, I'm sure he'd appreciate it if you used it. It fills in a few bits and pieces I've chosen to leave out.

Happy and better informed computing. Well, for me, at least.
