Is a computer essentially something physical or is it rather

The whole universe is in fact a computer simulation.

All that you know is an idea
a computer is something which we believe to be in reality and: expressed a deterministic output(s) when given measurable input(s).
A seasaw is a computer where tells you which side is heaviest.
It's most of all a matter of finding physical things which act out the computation model we desire and if impossible, compromising, using physical components to make something simpler until we eventually reach externally apparent complexity.
Looks what's confusing is as an English/human speaker you use a language which is evolved for our physical constraints while being helpful. So it's awkward and distractingly statemental (which makes you ask questions about categorization where they're pretty unnecessary).

Do you have any practical questions?

The existence of irrational numbers disproves that.

We won't get productive here op :^)

You can read up on the theory of building from a gate a combination circuit -> sequential circuit -> a complex one that fetches instructions from memory and captures the state in registers and sends commandvectors to execution units...
or to put it memely: We conjure the spirit of the computer with our spells.

numbers don't exist, just the concept of numbers

lad nobody is impressed that you listened to the first lectures are data structures

bad everybody sides with your snark

Its both.

Like everything else. There's the physical layer, transistors and such. And then there's the abstract layer like videos, games, music, etc.

Not in a conventional computer.
Maybe in a quantum computer.

lol are u stupid? im posting from my computer of course its physical u idiot.
of course its also an idea, after all u cant build something without an idea first. people didnt accidentally connect circuits and transistors and then discover they can do fast inverse square root calculations with it.
so of course a computer is an abstract idea like a turing machine but it's an actual physical object that was built based on the idea u dolt
