Do all servers have operating systems?
Can you run applications on any kind of server?
What is an example of an application that can be run on a server?
Believe it or not, I have searched for weeks on Google for answers to these questions, and have come up with nothing. If you can answer any of these I will send good vibes over your way!
If it did not have an operating system it would just simply be a box of hardware that did... nothing. You need an operating system for almost everything- calculators have them,tvs,phones,car park meters,digital cameras and a lot more. An operating system is what controls the device and makes and delivers the commands which the processor will process and etc. Maybe you should read up about operating systems as they are quite fascinating in one way :)
