When is the address in the instructional pointer updated?
This actually depends on the processor you are referencing; some processors update their IP (Instruction Pointer) before performing a command, and some perform it after the command. To find out if your processor is doing so before or after the command, use the instruction "mov ax,ip" in a debugger, and observe the value of ax. If ax contains the address of the mov instruction, it performs the update of IP after processing a command, while if it contains the address after the mov instruction, it performs the update before processing the command.

Physical address and logical address?
A logical (or virtual) address is a reference to a memory location independent of the current assignment of data to memory; a translation must be made to a physical address before the memory access can be achieved. A relative address is the address expressed as a location relative to some known point, usually the beginning of the program. A physical address, or absolute address, is an actual location in main memory.
