what is the relationship between application programs and the operating system?

The operating system is like the engine in your car; the
applications are like the transmission, brakes, air bags, etc..

Pop

The operating system provides the foundation for applications to run and
manages the hardware. When you launch a program the OS allocates memory and
loads executable code and data there from the hard drive. It keeps track of
the instructions being executed and passes them to the CPU. A multitasking
OS also manages the interaction of programs giving each their share of
processor time and system resources. Programs use services provided by the
OS to read and write files, print, communicate, etc. The interface that
programs use to call upon these services is called an API (Applications
Program Interface).

It's an interesting question and could be given a much longer answer, but
that should give some basic idea.

Salut/Hi sunshine,

The operating system is like the sewage system in your house. It keeps
everything running!

Applications are what run in your sewage system.

Remember that when next you read about an upgrade to some super duper new
operating system. It's no more glamorous than your drains! All you ask is
that they should work perfectly and never cause a smell.

I get tired of the car analogies and thought I was looking forward to
reading something different. Wasn't expecting a sewage parallel. Accurate
but the imagery stinks. ;^)

One of my favorites is the house analogy. Simple version:
Hardware = foundation
Operating system = house structure built on the foundation
Applications = individual rooms dedicated to specific purposes

Most men can understand a car analogy better than anything connected to
house building regulations..

I like the sports analogy where the OS is the field and applications are the
players.
