Hexadecimal usage in devices . Possible or not?

Which are the devices that work based on octal and hexadecimal system ?

Do microcontrollers work on hexadecimal system ? if YES how ? because we don’t have any material that can work on 16 possibilities (states)

Why computers use Binary instead of hexadecimal ?

computers don’t use hexadecimal because we don’t have any hardware to work on those many possibilities so how is this possible that some device work on hexadecimal while others can’t

hello @rishabhsaklani391
for all octal ,hexadecimal or binary related doubt check this->
article

i cannot comment much on this. as this require knowledge of microprocessor(ask someone who have electrical background).

btw if u are confused with 16 bit microprocessor then there 16 indicates that we can store 2^16 different values.
and we use hexadecimal (while studying) because its it makes readable( if we use binary then we have to write 16 digits but in case of hexa we need to write only 4 digits).
but in computers it all binary 0 or 1
