Want to learn coding for open source projects, or for job opportunities? Well, since I, the creator of this fake non profit, knows nothing about most coding languages, you can find some good tutorials at this website:https://www.programiz.com/ . Now for an overview of coding languages:

Objective C: A subset of C, and was used in early MacOS and iOS development until swift was released. You can still write programs in it in Xcode. Any C code is valid Objective C code.

Swift: Apple’s programming language, which is slowly replacing ObjectiveC in their OSes and is the recommended for 3rd party Apple apps.

C: A low level language that most kernels for operating systems are based on. Not ideal for games unless prioritizing optimization. Good for Windows and Linux applications.

HTML: A markup language that is the basis for all websites. Very simple.

CSS: A language used to stylize websites. JavaScript:

A language used for interactivity on websites.

Python: A High level language that is excellent for beginners and small games and software

C++: An extension of C

SQL: A language used to manage data, so it would be good for server side development.

Rust: A language focused on speed, reliability and beginner learning.

How computers work

A computer works using transistors. These transistors can have variable electrical values, determined by boolean algebra.

AND: True and True→1 True and False→1 False and True→1 False and False→0

NAND: True and True→0 True and False→0 False and True→0 False and False→1

OR: True and True→0 True and False→1 False and True→1 False and False→0

XOR: True and True→1 True and False →0 False and True→0 False and False→1 All logic gates can be made from a NAND logic gate. Now, in modern times a photo lithography will etch billions of transistors into a 300mm silicon slab and make a complex web of transistors, and when voltages are run through it, it will have an output. Essentially, we tricked a rock into thinking with electricity and light. There are a few components that are in a computer:

CPU(Central Processing Unit)Does the main thinking.

GPU(Graphical Processing Unit)Processes the graphical output

PSU(Power Supply Unit)Powers the components with steady power

RAM(Random access memory)Holds information needed to accessed quickly

Motherboard: Holds everything together

Storage device:holds long term data When assembled, they communicate and produce a display output and finally compute.
