Computer Science Basics
Binary (or base-2) a numeric system that only uses two digits — 0 and 1. Computers operate in binary, meaning they store data and perform calculations using only zeros and ones. A single binary digit can only represent True (1) or False (0) in boolean logic.
At the most basic level, Computer-Generated Imagery (CGI) is the creation of still or animated visual content with computer software. CGI most commonly refers to the 3D computer graphics used to create characters, scenes and special effects in films, television and games. (We will be working with this using pixels- nothing too complicated!)
Computers can't actually see, but there are tools out there and methods for making computers “see” the same things we humans can. ... Since computers see images as millions of individual pixels each with colour and alpha values it's difficult for a computer to determine if there are “things” in the image, so we remove data.
In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code.
