You could back up your whole hard drive on a floppy diskette
You're the biggest joke on the Internet
I can only conclude that he did understand the distinction between RAM and hard drive space. The song is full of jokes that show a deep understanding of the topic. Indeed I don't find any nits to pick.
But as I said elsewhere in this thread, I have been surprised in the past by people I would have described as fairly tech-savvy, who still called hard drive space "memory".
However, if the two phrases are related (as opposed to just being adjacent in the song), at this point I'd guess Al does probably know the difference, and the relationship is intended to be intentionally over-the-top absurd bragging.
I mean, “memory” in the computer sense is by analogy t memory in the brain sense, which is used for both short and long term storage (and I’d argue more commonly for long term storage). It therefore doesn’t seem unreasonable to me for people to call a computers long term storage it’s “memory”. The function of a hard drive is to remember things.
It goes the other way too, RAM is a type of storage, which is the terminology IBM uses (and I think has used since the 60s or so).
That's why I always had to make sure to say "RAM" when I meant memory in the 90s.
Where did it do that?
That's not really incorrect, though. RAM is random access memory, as opposed to memory that has other access patterns.
It's less common these days, but among people who learned to use computers in the 80s, you'll still hear some use "memory" to refer to storage that isn't RAM.
Swap space on disk is a cache of RAM, if you want to go down that path - but RAM and disk support entirely different purposes.
