You can consider programming as providing directions to a computer to do something you want it to do – which may sound really comparable to how you run your desktop. Simplistically, the only distinction in between what you are doing now as a computer user and what you may do as a computer developer is that the guidelines are conserved someplace so they can be used over and over.

Programs can be as basic as a set of guidelines kept in a text file for doing some ordinary job, or the os that your computer uses which can need countless lines of code. What they can do incredibly well is follow directions. What are these directions, anyhow? At the level that a computer comprehends, these have to be extremely accurate, extremely in-depth, and really total detailed instructions, and they need to remain in a form that the processor and other parts of the computer can understand – which is as little electrical pulses which human beings aren’t efficient in giving off (a minimum of not at this time).
In a manner, you can think about a computer program like a recipe: a set of directions that can be followed to produce an outcome. When it comes to a recipe, the directions are used by a human and can for that reason be a bit detailed, neglecting a few of the information. If a recipe guideline is to “put the mix into a blender and whip up until frothy”, it is presuming that the human understands what a blender is, and where it is, and how to set it up, and how to use it – and also what put ways, and what frothy ways, and so on. The human chef is anticipated to fill out the spaces. A computer can’t do this – it has no concept what anything suggests, other than for a couple of extremely easy directions. The way we do this is to provide the human a way to write guidelines that can then be equated into something the computer can understand. The “way to write directions” is called a programming language.
What a programming language enables us to do is to write directions for the computer in a basically human understandable form that can then be equated into something the computer can deal with. The human legible guidelines are usually called (you thought it) – code! Each line of human legible code equates into countless comprehensive computer guidelines. Once the translation is done the outcome is kept in some form such as a file or set of files (or in computer memory sometimes), and each time the software is run, the computer will follow the directions and (ideally) the program will do whatever it is that it is expected to be doing.
It is frequently envisioned that you have to be a genius to be able to write beneficial software, practically anybody who is computer savvy and has an interest in becoming a power user can learn to program. Most software is composed of typical people with specialized knowledge and abilities.
