And the numerical system used in computers is binary or base 2. Each
instruction would have a unique binary representation providing the control
of the datapath that would cause the desired action upon the data.
An instruction such as INCREMENT X might look like:
00110111 000000000110011100010011 in a simple computer with a eight bit
opcode (256 possible instructions) and a 24 bit memory address operand (16
MB memory).
Where 2 to the nth power provides the number of possible instructions or the
number of memory locations where n is the width in bits.

| (...) Your kidding?? The term "code" dates back (at least) to the "opcodes" used in machine language (ie. an even lower level than assembly). The term "opcode" refers to Operation Codes or "instructions" which may in many cases have required an (...) (24 years ago, 17-Feb-01, to lugnet.robotics)
