A computer is a machine that performs computations.

A programming language is a notation for describing a computation.

A programming language is a readable form for describing a computation that needs to be translated, usually via a compiler, to a pretty much unreadable machine code format that the computer understands.

• program text is legible (readable by humans, perhaps not easily )
• binary code is illegible (not legible, not readable by most humans)

A programmer is a person who takes requirements and implements a computer program that meets those requirements.

Programming a computer is like learning a foreign language.

You can get started in a few minutes, but after a lifetime there will still be things to learn.

To call yourself a "real" programmer, you should have written at least one program that someone else uses on a regular basis to do something useful.

Some programmers create "new" code from scratch.

Some programmers maintain "old" code.

Programmers writing "new" code glue together pieces of existing code using a SDK (Software Development Kit) , software library, etc., to do new things.

Many programmers learn and use only one programming language and many programmers only work with and support one program or software system.
