electronics - converts numeric values into electric signals? -

suppose, enter 15 in computer. numeric value. how computer can convert numeric value electric signals like: 1 -> true-> pass electricity 0 -> false -> don't pass electricity

experts numeric value converted in binary. think 1 thing, computer electric machine , there flow of electron, nothing else. how type of machine can convert number electronic signal?

if cannot understand question ask me.

there plenty of literature , ressources on how computer works. try wikipedia, youtube, google find suits level of understanding.

for question alu might of special interest: https://en.wikipedia.org/wiki/arithmetic_logic_unit

also read memory, control unit , transistors.

a computer nothing combination of memory, processors , data busses. super miniaturized electronic circuit.

a modern cpu alone comprises 3-5 billion!!! transistors.

you can store logic states (bits) https://en.wikipedia.org/wiki/flip-flop_(electronics) compare them https://en.wikipedia.org/wiki/logic_gate arrithmetic operations on them... name it.

all happens in hardware. software representation of hardware states. software nothing huge amount of bits arranged in clever way these bits useful. in case of computer arrange bits in way displayed on screen.

you think you're doing in software hardware. entering number on computer nothing pushing electric switch triggers chain reaction in computers electronics ends polarization state on som of lcds pixels. never had software hardware. there.
