PHP-General - Difference between Web Development and Software Development

Sometime the things which we heard daily and also implement it in a daily basis, still we don't know exact meaning of it. here is the same thing happen with me.

can someone please help me to understand the difference between Web Development and Software Development?

Neither have precise definitions, but I would consider web development to be a subset of software development; ie: web development is software development that deals with powering a website.

still not satisfied. guys post some proper explanation

Usability and accessibility are probably different between web sites and web apps on one side and desktop apps on another and mobile device apps on yet another.

Also the languages used for web development vs desktop application development are often different. (I'm not going to mention specific languages because there are so many.)

I recommend you wait a few days and if no one gives you a better explanation here, go ask somewhere else (though I doubt anyone will improve on this much).

I tend to consider web development as something that involves a UI that the users interact with (i.e.) it involves HTML and javascript at some point. (PHP, perl, ruby, java etc. may be involved, but HTML/JS does enter into it at some point)

Software development is something that involves programming in general and not just a UI. For instance, I write a lot of backend processing jobs in perl and java (i.e. some of the same languages I mentioned as part of web development), which have no UI at all and do some major data crunching. I also write stuff in C which does serve up some HTML, but the majority of that code is really business logic and daemon code, so I consider that work more as generic software development than web development.

"Software" is too broad of a subject anymore. We keep saying things like "software development" as if it has a strict definition, like "writing." Basically "writing" and "software development" have the same definition, just the language is changed.

If you asked someone what he did for a living and he said "I write," what would that mean to you? Is he a journalist? A columnist? A humorist? A cruciverbalist? A novelist? A biographer? Does he write the warning labels on children's toys? Does he write marketing copy for a large corporation? Does he write legal disclaimers? User's manuals? Technical documentation?

When someone says they're a software developer, you have to ask the same questions. Desktop programs? Games? Web programs? Flash apps? Phone apps? Drivers? Operating systems? Embedded control systems? If embedded control, is it robotics? Cash machines? Registers? Microwaves? Cars?

So in summary: "Software engineering" is a catch-all term that means "puts code on the screen which will probably be executed by a computer." Web programming is a specific kind of software engineering, one of thousands.
