C++ Memory addresses?

Question

How do memory addresses work?

In 32-bit a memory address is an hexadecimal value like 0x0F032010, right? But do those values point to bytes or to bits?

And what lies between two memory addresses like 0x0F032010 and 0x0F032011

Answer 1

In 32-bit a memory address is an hexadecimal value like 0x0F032010, right?

Its a number. A location in memory. It is bounded by the start and end of memory, which is starting at some value and ending at some value.

But do those values point to bytes or to bits?

It is generally accepted that addresses point to the smallest addressable unit, which is a byte. Most modern CPUs are defined this way. This is however not always the case.

Dragons. Or nothing, as there isn't anything between them.
