The device driver software controls every I/O (Input/Output) device. It acts as an interface between the hardware device and the operating system, allowing the operating system to communicate with the device and manage its functions effectively.

1. BIOS (basic input/ output services)
the device on which complete operating system is stored
The BIOS manages the data between the operating system and all input and output devices attached to the system. The programs that manages operation and data transfer between computer programs and the attached devices are called device drivers, device handlers. device processors, io handlers, and other names depending on the computer and operating system. These programs are usually included with the operating system or added to the operating system to support devices not originally known to the operating system. On a PC (the common Personal Computer) these programs are included in the flashable read only memory called the system BIOS (Basic Input Output System). Besides basic system startup testing and functionality, it also provided a device driver interface for software to access standard known devices on the machine without the programs having to know the specifics of hardware programming. Some operating systems and standalone software supply their own device drivers (ignoring BIOS provided versions) either to support devices not supported by the BIOS or to supply more efficient or more capable implementations of device drivers.
It is spelled 'hard drive'. Considering the nature of a hard drive, you might say "both". All hard drives provide input and output. Input is performed when your operating system reads a sector looking for data or a program. Output is performed when your operating system writes to the hard drive to swap or store data.
It is neither. In addition to input devices and output devices, there are devices called storage devices. The hard drive of a computer is a storage device: it contains the operating system and any data or program files used by the computer.
Yes, you can write a "hello world" program without an operating system using bare metal programming. This involves directly interfacing with the hardware of a computer system without an intermediary operating system. The program can be written to access and output text to a display device without the need for an OS.

operating system is a complete operating system that works on a desktop computer, a notebook computer, or mobile computing device.
COBOL (common business-oriented language) is an operating system.
