Build computers in Minecraft: what do I have to consider - what is different from real?

Wants to build a computer in Minecraft. ALU, register, RAM, … All the stuff. I already know that, I'm a computer science student.

I was once told that you have to implement a certain component in Minecraft DIFFERENT from real. Respectively. Something else to add to the computer that a real computer doesn't have. Unfortunately at that time I couldn't remember what it was about. So I ask in general terms:

Do you know what he meant, or do you generally know things to consider when building redstone computers?

There are not many PCs in Minecraft yet. You just have to build the components in Redstone - this is often difficult because of the complex gate controls.

If you're building computers, you're probably going to be building big things, resp. That you want to try that at all. The first thing that would occur to me would be render distance and timing, even if Redstone is actually quite fast, such a simple calculation can take a long time. In addition: please do not use Bedrock, the version does not seem to have a reliable redstone behavior (according to Mumbo Jumbo).

Otherwise, I can recommend the old videos from TheJoCraft, who has already built one or the other computer and explains the whole thing quite well step by step ;-)

What do you mean by complex gate controls?

I can just build an ALU or something similar, e.g. ALU 74181.

A 4-bit control input, which specifies the gate to be used, and two 4- or 8-bit inputs which are then compared bit by bit with the gate to be used. Or do you do it differently in Minecraft?

The question is more for technicians, or for people who have ever built PCs in Minecraft - unfortunately such trivial tips are of little use to me.
