What is Operating System:
Operating System is a peace of software that acts as an intermediate between the hardware and the users. Operating System or OS is a software that you must be install at first on your computer, otherwise without an operating system, no software programs can run. When you start your computer then you observe that some times takes to load your home screen, because thats time install your device(computer,mobile,laptop,tablet etc) operating system on your device background. It is install while you start your device and stop when you shut down your device. An operating system is the responsible for the operation and smooth running of a device. Most general purpose device will have an operating system to manage the running of other programs and controls the system’s inputs and outputs. You can say the operating system is middle man because the users can not give the command directly to the CPU(Central Processing Unit) on machine language and not can the CPU interact the users directly. So there needs to be a middle man which communicate and translate all interaction between the user and computer. |

Characteristics of Operating System:
- Device management: Operating system keeps track of all devices, device management is responsible for managing all the hardware devices of the computer system. And the operating system also decides which device to be given, when and how long it will be given.
- File Management: Operating system is used to managing files of computer system. It allocates and de-allocate resources and decides which programs to be given the resources, that is to be allocated.

- Portability: Portability was the one of the main features that made OS so popular among the users, but portability doesn’t mean that it is smaller in file size and can be carried on pen drive, CDs and memory cards.
