Ask HN: Could you recommend Computer basics courses?

[sliekasbekelniu]

Hi, there HN community,

there are a lot of possibilities to learn stuff online these days. Could anyone recommend any computer basics courses? In Basics I mean that would go in details how and why processors work, how does cache fit in, why do we need RAM/motherboard/etc/etc. Why such transistor arrangement and electronics component selection make a processor work and such things..

Not a native speaker so is this basics or this is advanced (because of going in depth)?

Anyway both basics and advanced are ok for me - just want to deepen my knowledge into how stuff works down there.

Thanks.
