What is the binary code made up of?

Answer 1

Binary code is made of 0s and 1s (hence, binary). Virtually every processor in use today understands only "off" and "on" signals (usually 0 volts for "off", and some usual maximum, such as 3.3v, 5v, or 12v) for "on". These zeros and ones are then grouped together into larger units, typically a multiple of 8 bits (a single "off" or "on" signal, or 0 or 1). Those larger units are then interpreted by circuits within the processor as an "instruction", which tells the processor to do something, such as adding two numbers together or moving data from one area to another.

Answer 2

the cental processing unit in a computer (CPU) is basicaly made up of lots of switches that can be in either two states, on and off. so the 1 in binary is on and the 0 is off and that is how a computer manages instructions that it gets from the user (you). say you have a number eg 12. binary goes up in 8bits, so 8 spaces each with its own value (i think it goes up in 8 or doubles i cant reamember) and you put a 1 where you want but it must add up to the number you want, in this case 12.
