Programming is the process that professionals use to write code that instructs how a computer, application or software program performs. At its most basic, computer programming is a set of instructions to facilitate specific actions. If you're wondering what a computer programmer is, it's a professional that creates instructions for a computer to execute by writing and testing code that enables applications and software programs to operate successfully.
Computers can do amazing things, from basic laptops capable of simple word processing and spreadsheet functions to incredibly complex supercomputers completing millions of financial transactions a day and controlling the infrastructure that makes modern life possible. But no computer can do anything until a computer programmer tells it to behave in specific ways. That’s what computer programming is all about.
At its most basic, computer programming is little more than a set of instructions to facilitate specific actions. Based on the requirements or purposes of these instructions, computer programming can be as simple as adding two numbers. It can also be as complex as reading data from temperature sensors to adjust a thermostat, sorting data to complete intricate scheduling or critical reports or taking players through multi-layered worlds and challenges in games.
