system software

The system software is the central software of systems. It forms the interface between the hardware components and the application programs and controls the functional processes between the hardware components of computers or other systems equipped with processors.

The system software ensures that application programs can use the available resources and peripheral units. The best known system software is the operating system. It performs central functions by managing other programs and controlling communication between the central processing unit, main memory and peripheral units.

In addition, the system software supports everything from turning on a computer to calling the application programs. Thus around the BIOS for the data flow management between operating system and peripheral devices, around the booting, with which the operating system is loaded into the main memory, around the Assembler, which translates mnemonic program codes into machine codes, around the device drivers for the peripheral devices and around development tools such as compiler and debugger.
