BY VINCENZA J. O'GRADY

INTRODUCTION

In the modern age, there’s few new mediums as vast as cyberspace.
What computers can do now far surpasses what they could do in the past.
This presentation seeks to explain the basics of how a computer processes and runs websites.

COMPUTER PARTS

CPU: Short for ‘Central Processing Unit’. Does the majority of calculations, logic, and processing of a computer.
Executes the actual programs. Think of this as the brain of the computer
CHIPSET: Connects the CPU and memory, so they can exchange information.
RAM: ‘Random Access Memory’, stores data and code being used by the computer.
ROM: Memory that’s hard-wired into the computer.
BUSES: Send data between the CPU and various other parts of the computer.
GRAPHICS CARD: Also called a video card. Generates visual output on a monitor.

EXECUTING CODE

A programmer writes the code.
The computer loads the program and starts reading from the first instruction or ‘entry point’ of the code
The system running the code is called an ‘interpreter’. It translates the code into language the computer can read.
After translating, a computer can run the code. The program runs forever, either until it finishes, the user stops it, or it crashes.
