Coding is a computer programming language that is used to create apps, websites, and software. The information are stored in the form of codes. On and off switches control a computer's capabilities. These on and off transistors are represented by the numerals 1 and 0 in binary code. Computer is made up of an endless number of combinations of such codes. Computer programming languages were created to make binary code more manageable. Each of these languages has a different purpose, but they all allow programmers to convert crucial commands into binary code. To know what to do, each computer application requires properly written code. Thousands to billions of lines of coded text and numbers make up most software. The code instructs computers on how to operate in a step-by-step manner. Every coding language has its own set of rules. Ruby, Swift, JavaScript, Cobol, Objective-C, Visual Basic, and Perl are the programming languages.
