System software is designed to control and coordinate the procedures and functions of computer hardware. It allows for functional interaction between hardware, software, and the user. Nowadays, users interact with the operating system through a graphical user interface (GUI) on a monitor or touchscreen. The desktop of modern operating systems is a graphical workspace containing menus, icons, and applications that the user manipulates with a cursor, mouse, or touch of a finger. The disk operating system (DOS) was a popular interface used in the 1980s.
Windows 8.1 is an example of system software. Firmware is the operating software embedded in a flash memory chip, ROM, or EPROM for identification by the operating system. It directly manages and controls all activities of any individual hardware. Traditionally, firmware meant fixed software, as denoted by the word signature.
It was installed on non-volatile chips and could only be upgraded by exchanging them for new, pre-programmed chips. Nowadays, firmware is stored on flash chips which can be updated without needing to exchange semiconductor chips. The BIOS chip details the system firmware data. The motherboard firmware starts by activating all hardware and ensures that components such as processor, memory, and disk drives are operational. If all crucial components are OK, it will run the boot loader which will load the operating system.
If random access memory is faulty, the BIOS will not allow the computer to boot. Although they work differently, firmware complements controllers in several ways. Both give identity to hardware devices and cause the operating system to recognize the device. The main difference between them is that firmware will always be inside devices while drivers will be installed inside the operating system. Firmware updates come from device manufacturers (not the operating system). They are necessary if users want their computer's hardware to receive new hardware and software support.
The firmware will allow devices to work better with new and old operating systems and applications. Almost all devices and peripherals are integrated with firmware such as network card, TV tuner, router, scanner or monitor. Is it real software? The Start menu and desktop are typical examples. While the Start menu is different in Windows 7 and redesigned in Windows 10, Windows 8 and 8.1 emphasize Metro interface. Character bar and Snap view are some other features of Windows 8.Software is a computer program that acts as a link between user and hardware.
It also has another definition as an application consisting of a collection of programming language codes. Programmers create programs using a specific programming language which is then compiled into machine-readable code. The creation of this programming language still requires special software to design programs according to methods and structures of programming language itself. The operating system is a type of software core of the system located between computer hardware and end user.

In addition to operating systems, some people also classify programming software and driver software as types of system software.
