What is difference between a user and programmer?

Answer 1

In computers, a user is literally someone who uses the computer or the smart-phone or the e-reader. The user often is not an expert; he or she just owns the device and knows how it works. I am a good example: I'm an educated person, but computers are not my area of expertise. I know how to use various databases, edit a document, post something to a web-site, etc. But if you asked me about the technology of computers, I have no idea: I just know what steps I am supposed to take to make my computer do what I want it to do.

A programmer is someone who understands computers from a technological point of view. Programmers actually writes the code (the special language necessary to make the computer understand commands and perform various functions). Programmers often go to school to study computer technology, and they have expertise in writing routines (programs) that the computer will store. We users do not usually see those lines and lines of computer code, but we see the end result: thanks to the work of programmers, the computer will follow the commands the user types in.

Answer 2

A user is an individual who interacts with a computer system or software to perform tasks or access information without necessarily having knowledge of programming languages. On the other hand, a programmer is someone who writes, tests, and maintains the source code of computer programs using programming languages like Java, Python, or C++. Programmers have a deep understanding of algorithms, data structures, and software development principles, while users typically have a more limited scope of interaction with the technology.
