title: Program Counter?
body: <p>If I understand this correctly, the program counter points to the address of the instruction to be executed and in most cases you add four to the program counter to advance to the next instruction address. But say you have a program counter that's pointing to a word (e.g word 15) in memory and you want to advance to the next instruction, are you suppose to add 4 directly to 15 in order to get the next instruction?? Any explanation would be appreciated</p>
