Liberal Arts kind of guy who wormed his way into Information Technology here.
Part of my job involves explaining technology to people who have little technical aptitude at all, so I look for ways to break things down into the simplest, most commonly-understandable words.
I've noticed something: in my youth, people used the word "program" as a synonym for "software" or what we would now call "applications".
Lately (say, in the last ten-fifteen years) I don't see "program" used much at all.
Is there a reason this word fell out of favor beyond style? Is there a fundamental difference in an "application" vs a "program" that I'm missing out on, or could I use these interchangeably when speaking with less tech-savvy folks who need it in the simplest language possible?
