Binary Code

How software is made A computer program otherwise known as software is made up one and zero. This is known as binary and it is the only thing the computer understand. So how do we get from an idea to the finished software? Writing the binary yourself would be slow, tedious and take a way too long. Instead we all used something called source code. Source code is the instructions to the computer that is meant to be human readable with a little practice. Source code can be written in one of many different programming languages. These are the main ones in use today. Here is a very simple program written in a programming language called C++. This program simply display the words “Hello world” to the computer screen. In order for the computer to actually run the program, the source code must be turned into binary. This process is called compiling. Once we have our ones and zero, the computer then can run the program. If the are any mistakes in the source code such as a misspelled word or missing punctuation mark, the compile will fail and you won’t be able to run the software. Simple programs can be written by one developer in a reasonable amount of time. However, professional software may involve hundreds of developers and take a matter of years to complete.
