Low Level

All the examples, until now, were in high-level programming languages. The level of a language refers to how far it abstracts away the internals of the computer, which is where all code runs in the end.

This section, hopefully, will challenge a few assumptions you thought were true about computers, but were actually abstractions created on top of them.

Before you go, there is one common misconception about computers that I must address:

Computers are not just addition, subtraction, multiplication, and division machines. Modern computers would not be possible with just 4 basic operations.
