BIOS
An operating system runs common services for computer programs and manages the computer hardware resources. An operating system is necessary to run application programs.
basic input output system (BIOS)
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.

An operating system is a program that manages the computer hardware.It also provides basis for application programs and acts as an intermediate between the computer user and the computer hardware.
I guess you are asking about the difference between a Project Manager & a Program Manager. A Project Manager manages the project while a Program Manager manages the program. A program may be a collection of one or more projects
A kernel is the core program that runs programs and manages hardware devices, such as disks and printers. It executes the commands which provide by environment.
.. Loads and starts programs and DLLs .. Dispatches and halts programs for multiprocessing .. Manages memory .. Insures application programs do not execute prohibited operations such as accessing another program's memory and reading/writing to I/O devices .. Routes requests for services to the appropriate service handler program.
An operating system takes control by effectively managing user input. It also manages both external and internal requests. This can include program and application requests, along with information sent via keystrokes and other protocols. The main function of any operating system is to assist the CPU in facilitating user and program functions.
