What is the significance of operating system in program execution? How is the computer dependent on the operating system? Can anyone explain me the basic task performed by the OS?
Operating System is just a program as we write in programming. The only thing which makes it important is that it controls all the tasks performed by the hardware.
It can be understand as a connection between person and machine. It controls various features like taking input from keyboard/mouse, monitoring disk drives, memory allocation and a lot more things.
The operating system is the only piece of programming that makes a computer useful. Without it, your computer is only a piece of machine with no useful meaning. The operating system makes the computer powerful because of the many different things you can do. It can be used for learning, working, and entertainment. One of the basic tasks of an operating system is to boot the computer.
This process takes place the moment you start your CPU. It initializes all the devices connected to your computer like the memory card, video card, sound card, network or Ethernet card, USB ports, mouse port, keyboard port, printer port, game port, serial port, and more. Basically, all the devices connected to the motherboard are initialized so they can be used within the operating system.
When a device has not initialized properly, it cannot be used within the operating system. You need to restart the computer to reinitialize the device properly and can function within the operating system.
