x/8 bytes as they are holding addresses in an x-bit system, 16 bits for DOS, each took 2 bytes there.

pointers occupy memory regardless of whether they point to anything or not. How much memory they occupy depends on the nature of the object they
point to.

a pointer always has 4 bytes on a 32bit system and 8 bytes on a 64bit system.
you can test it with this code:
printf("%d\n", sizeof(void *));
