Programs work by instructing physical hardware to do things. A program is just a series of numbers usually represented in hexidecimal format. A computer's CPU will execute these instructions which basically involve moving or manipulating data. But programming with hexidecimal numbers as instructions is confusing we we use assembly code which is just a nunomic for the hexidecimal numbers.

So E8 becomes MOV which moves a byte (depending upon the architecture) somewhere. Unlike with high level languages in assembly you need to pysically move your data around the CPU, into registers and mathematical units.

Holy fuck I suck at this. Assembly is like doing everything by hand, high level 'programming' languages are like using power tools.

Here's a very primitive CPU built in minecraft for fun.
