Introduction To App Development So how does coding work, really? A computer can only understand two distinct types of data: Anything that a computer can do is nothing more than a unique combination of some transistors turned on and some transistors turned off. Binary code is the representation of these combinations as 1s and 0s, where each digit represents one transistor.

Binary code is grouped into bytes, groups of 8 digits representing 8 transistors. Modern computers contain millions or even billions of transistors, which means an unimaginably large number of combinations.

But one problem arises here. To be able to write a computer program by typing out billions of 1s and 0s would require superhuman brainpower, and even then it would probably take you a lifetime or two to write. Put simply, a programming or coding language is a set of syntax rules that define how code should be written and formatted.

Thousands of different programming languages make it possible for us to create computer software, apps and websites. Instead of writing binary code, they let us write code that is relatively easy for us to write, read and understand.

Introduction

Each language comes with a special program that takes care of translating what we write into binary code. Because different languages are designed to be used for different purposes — some are useful for web development, others useful for writing desktop software, others useful for solving scientific and numeric problems, and so on.

Low-level languages are closer to the binary code a computer understands, while high-level languages bear a lot less resemblance to binary code. Nearly all of the main programming languages in use today are high-level languages.

Programs A program is simply a text file, written in a certain coding language. The code inside a program file is called the source code. Every coding language has its own file extension for identifying code files written in that language.

To make a program, you write the code in a plain text editor like Notepad and save the file to your computer. For example, the below line of code could be the contents of a very short Python program called hello. That varies between coding languages. Some languages save a separate binary file that the computer can directly run, while other languages have their programs run indirectly by certain software.

For example, a JavaScript program file would get run by a web browser like Chrome. In the case of our hello. If you were to enter the code into the command line and press enter, the program gets run and the command will get executed.

It only understands on and off. To do that, a number of things happen: The source code is translated into assembly language. The assembly code is translated into machine language. The machine language is directly executed as binary code.

The coding language first has to translate its source code into assembly language, a super low-level language that uses words and numbers to represent binary patterns. Depending on the language, this may be done with an interpreter where the program is translated line-by-lineor with a compiler where the program is translated as a whole.

Your screen, operating system, photos, videos, the Internet, Facebook, your online bank account, and this website — all these things can be constructed from nothing but 1s and 0s.

A file has two key properties: a filename (usually written as one word) and a lausannecongress2018.com path specifies the location of a file on the computer.

For example, there is a file on my Windows 7 laptop with the filename lausannecongress2018.com in the path C:\Users\asweigart\lausannecongress2018.com part of the filename after the last period is called the file’s extension and tells you a file’s type.
