What does the programming hardware physically do to the PIC IC? How does the PIC know what your telling it to do?

Never heard of a PIC except in the context of 'pilot in command', which clearly is not what you are talking about. Care to elaborate?

I believe you are talking of PIC microprocessors (and not of Pilot In Command!).
PICs are just processors with limited "commands" (such as ADD, SUB, MUL, MOV, etc...), a limited number of input/output lines, a limited amount of RAM and a small EEPROM.
You use a small piece of software to write a code in assembler.
Using a programmer, you download the code into the PIC EEPROM.
When you power the chip afterward, it starts reading its intructions and execute the program...
Welcome to the world of assembler!

I have done considerable programming on the PIC processor, with literally millions of units assembled and sold with these processors inside. For more information I suggest that you go to the manufacturers website at http://www.microchip.com
Click on the 8 bit processors for more information.
