Phase $1$: Basic Input and Output

Introduction

As we boot up our operating system and begin executing code, we will consider our basic

architecture: CPU, RAM, and I$/$O$.$ The code that we download is comprised of instructions

that located in RAM and subsequently executed by the CPU. Beyond the CPU, however,

we will explore interactions with external hardware components and basic input and

output operationsPhase $1$: Basic Input and Output
