Which Software Provides an Interface Between Hardware and User?

The software which provides an interface between hardware and user is operating software or OS and its functions are:

• Hiding the complexness of hardware from the user.
• Managing the hardware's resources. Hardware resources include memory, processors, memory, I/O devices, and data storage.
• Handling "disturbance" generated by the Input and Output controllers.
• Sharing of I/O between CPU and many programs.
• There are two types of software: System Software and Application Software.

Operating System is a set of programs that operates computer hardware and provides data for application software. In other words operating system works as the interface between input/output and hardware.
