What is the most under appreciated computer component?

And why is it the super tiny resistor

that's not the gpu bios switch

This is underappreciated components, no negativelly appreciated ones.

are you dumb? just asking for a friend.

have you ever seen a gpu bios switch and said to yourself: "what a useless piece of shit"?
pro tip: you haven't

Actually, you reminded me of something I was wondering about a while back.
Is it at all possible to do resistor-free computing?
Resistors are one of the biggest heat-producers in electronics, can they be ditched?

Does anyone even care to try?

Just use a lower voltage.

Fuses, because you always need protection.

That might be the stupidest post I've read today. Good job.

>is it possible to build a frictionless object?

But could you do that at computer-scale, rather than just simple circuits?
Also, current.

Great answer, 10/10 would read again. Shared it on Reddit, Digg, Facebook, Pornhub and Twitch.

Not even remotely the same.
Friction isn't a component of reality, just a result of things combining and the forces interacting.
Current flows don't NEED to be restricted by resistors, superconductors don't, and we can make circuits that don't require manually placing higher resistances in serial or parallel with components and they still work.
What I care about is whether COMPUTERS can be reliably built without them right now.
Simple circuits are trivial, but the large variety of voltages and currents used across components may well triple the size of them to be able to run resistorless.

We could easily use ternary computing right now, and we'd be better for it, but nobody wants to because binary is so ingrained with computing.
Balanced Ternary is a fucking dream man. Fuck binary.

Your chips have resistance, thermal loss is a thing

Resistors and resistance are two different things you brainlets

Well yeah, inherent resistance is always going to be there until (IF!) we can get superconductors there.
What I'm wondering is whether all the components of a computer can be redesigned without using any added resistance anywhere.

Better way to phrase it, can you replace a resistor with anything else that doesn't cause such a shitfest of lost energy to heat while still retaining its useful function?

This.

Damn straight

It depends on the circuit, if you're worried about power usage, sometimes the solution is to use bigger resistors rather than removing them.
Anyways, on computers it's mainly the CPU and GPU the ones who waste the most power and they are both digital parts based on CMOS, which only uses considerable power when switching states.

Look up "reversible computing".
