An OS (Operating System) is the main language of a computer system. OS is the main system software that manages computer hardware, functions, memory, CPU, schedule tasks, software resources, and controlling peripherals.
The Operating system (OS) can allow us to communicate with the computer’s language. Without an OS, a computer system is useless. The OS is an intermediary between software programs and computer hardware.
Computer Hardware functions such as input, output, processing, and storage (memory allocation). The computer hardware of the Computer includes the physical parts of a computer system, such as the central processing unit (CPU), monitor, keyboard, mouse, computer data storage, graphics card, sound card, speakers and motherboard, etc.
Computer software functions such as allocating system resources, monitoring system activities, disk, and file management. The parts of the system software (OS) are Network and Internet Services, Hardware Level of OS, Logical Level of OS, Graphics Engine, User Interface (UI), System Services, Command Shell, and System Utilities.
The most used desktop operating system (OS) is Microsoft Windows OS (82.74%). macOS (previously called OS X) by Apple Inc. is in second place (13.23%), and the third is Linux OS (1.57%).
Examples of mobile operating systems are Apple iOS and Google Android. In Mobile devices OS (Operating System) Android’s share is up to 87.5%, Apple’s iOS share 12.1% and other OS shares 0.3%
Computer software divided into categories; System software or operating system, programming software or programming languages, and application software. We are using applications daily. These applications are created by using programming languages like C, C++, C#, Java, Python, etc.

Types of Computer Software
1. Systems Software
The system software is the software used by the computer system to converts inputs from output sources into a language that a machine can understand. Nearly, the OS coordinates with the different hardware components of a computer system. An example of the system software is the operating system (OS).
2. Programming Software
It is a kind of computer software which is used for computer programmers. Programming languages are used to create Programming Software’s that is run on the operating system of a computer.
3. Applications Software
Application software is a program which used to interact with a computer system. Such as system applications like Microsoft office suite, Photoshop, VLC media player, Mozilla Firefox, Opera, Google Chrome, etc. Without an OS application software can not be run or installed.
Software developers or programmers are used programming languages to create applications; they must execute, run, and compile for a specific operating system. This means OS (operating system) communicates with the hardware and a particular application program interface (API).
The popular programs are cross-platform, which means they have been developed for multiple operating systems (OSes); some are only available for a single operating system (OS).
