operating system - iPhone - why only one application at a time -

-

I tried to find an explanation for this question, but could not.

I am new to iPhone development and I was wondering why the iPhone can not allow more than one app to run / run at a time?

I am pretty sure that this is a design feature rather than a lack of functionality.

Will someone tell me in technical / non-technical terms why you can not run more than one app in the iPhone.

Thank you very much.

Here 'why:

on discussion boards related to other smartphones such as Android , Users are asking such questions as "Why does my battery sometimes run really fast?", And "Why does my phone slow down and slow down?" Essentially received answers from the society are clear: go to the task manager on the phone and stop some external programs you are running. It is not a difficult thing for a lucrative user to manage your available resources.

On the iPhone, Apple decided that they evaluate the overall experience with flexibility, and so they decided to limit the phone to perform one (third-party) work to stop the above situations Whether you agree or disagree with this decision, the person is different.
