No, in almost all cases only the actual executable code of a program is copied.

It will be stored in a specific memory cell. The address of this location is not hexadecimal. Hexadecimal is only a representation of the number of the address. It can be represented as anything, decimal, octal, bananas, etc.

The File Allocation Table has got nothing to do with all this. Do not confuse RAM memory with hard disk space.
Off topic: information is not stored randomly at all. There is a very strict system behind the storing of data on a hard disk, and that is in most cases sequential (unless some parts of the physical places on the hard disk are already in use. But in that case, the next free place will be used).
