What is System Software? – Definition from WhatIs.Com
System software is a type of computer program used to run a computer’s hardware and application programs. If we think of the computer system as a layered model, the system software is the interface between the hardware and user applications. The operating system is the most well-known example of system software. The operating system manages all other programs in a computer.
System software is used to manage the computer itself. It runs in the background and maintains the basic functions of the computer, allowing users to run higher-level application software to perform specific tasks. Essentially, system software provides a platform for application software to run on.
Important Features of System Software Computer manufacturers typically develop system software as an integral part of the computer. The main task of this software is to provide an interface between the computer hardware that they manufacture and the end user. The system software generally includes the following features: High speed. System software must be as efficient as possible in order to provide an effective platform for higher level software in the computer system. Difficult to manipulate. It often requires the use of a programming language that is more difficult to use than a more intuitive user interface (UI). Written in a simple computer language. System software must be written in a computer language that the central processing unit (CPU) and other computer hardware can read. Close to the system. It connects directly to the hardware that enables the computer to operate. Versatile. System software must communicate with both the specialized hardware it runs on and the higher-level application software, which is usually hardware-independent and often has no direct connection to the hardware it runs on. System software must also support other programs that depend on it as they evolve and change.
Types of system software System software manages the basic functions of the computer, including the hard disk operating system, file management utilities, and operating systems. Other examples of system software include: A complete picture of the software stack. The system software includes the firmware through the operating system levels of this model. The BIOS (Basic Input/Output System) starts the computer system after switching on and manages the data flow between the operating system and connected devices such as hard disk, video adapter, keyboard, mouse and printer.
Starts the computer system after switching on and manages the data flow between the operating system and connected devices such as hard disk, video adapter, keyboard, mouse and printer. The boot program loads the operating system into the computer’s main memory or random access memory (RAM).
loads the operating system into the computer’s main memory or random access memory (RAM). An assembler takes basic computer instructions and turns them into a bit pattern that the computer’s processor can use to perform its basic operations.
takes basic computer instructions and converts them into a bit pattern that the computer’s processor can use to perform its basic operations. A device driver controls a specific type of device attached to your computer, such as a B. a keyboard or mouse. The driver program converts the operating system’s more general I/O instructions into messages that the device type can understand. In addition, system software may also include system utilities such as Disk Defragmenter and System Restore, and development tools such as compilers and debuggers.
Operating Systems The computer’s operating system is a well-known example of system software. Common operating systems are Microsoft Windows, macOS and Linux. Unlike other types of system software, the average computer user regularly interacts with the computer operating system through its graphical user interface (GUI) and, for some operating systems, through a less complex command line interface (CLI). Since a GUI is a program that sits on top of the operating system, it can be referred to as application software and not system software. In other words, the GUI is an application software that allows the user to manipulate parts of the operating system.
Important Tasks of the Operating System The main task of the operating system is to manage the software and hardware resources of a computer. It is the main control program of the computer. The operating system controls and manages all other programs on the computer, including application and system software. The operating system creates an environment in which all other computer programs run and provides services to those other applications. Operating systems perform tasks. Five of the most important are the following: file management and process planning. The operating system allocates resources and prioritizes which programs should get the resources and in what order. For example, a digital audio workstation application may require a certain level of processing power when used. The operating system decides how much performance the application gets from the CPU and manages the impact of that allocation on other applications. If a more critical process is running elsewhere on the computer, the operating system may sacrifice some of the performance that the Digital Audio Workstation has requested, for example to ensure that the other process can complete. Processor and memory management. The operating system allocates the computer’s memory to a process when it needs it, and frees it when the process is complete. error detection. The operating system detects, tracks, and debugs errors in other programs on the computer. Security. The operating system uses passwords to protect the computer’s programs and data from unauthorized access. control and management. The operating system uses compilers, assemblers, and interpreters to control and manage other programs on the computer. These language processors are pieces of systems software that translate the high-level languages—Java, Python, and C++—in which many computer programs are written into low-level machine code instructions, which are essentially a series of ones and zeros that the computer’s CPU can read.

What is an operating system?
An operating system is the main piece of software that runs on a computer. It manages the computer’s memory and processes, as well as all of its software and hardware. It also allows you to communicate with computer without knowing how to speak computer language. Without an operating system, a computer is useless.
Watch the video below to learn more about operating systems.

task of the operating system
Your computer’s operating system (OS) manages all of the software and hardware on the computer. Most of the time, several different computer programs are running simultaneously, and they all need access to your computer’s central processing unit (CPU), memory, and data storage. The operating system coordinates all of this to ensure each program gets what it needs.
types of operating systems
Operating systems are usually pre-installed on every computer you buy. Most users use the operating system that comes with their computer, but it is possible to upgrade or even change operating systems. The three most common operating systems for PCs are Microsoft Windows, macOS and Linux.
Modern operating systems use a graphical user interface or GUI (pronounced gooey). A GUI lets you click icons, buttons, and menus with your mouse, and everything is clearly displayed on the screen using a combination of graphics and text.
The graphical user interface of each operating system has a different appearance. So when you switch to another operating system, it may seem unfamiliar at first. However, modern operating systems are designed to be easy to use and most of the basic principles are the same.
MicrosoftWindows
Microsoft developed the Windows operating system in the mid-1980s. There have been many different versions of Windows, but the latest are Windows 10 (released in 2015), Windows 8 (2012), Windows 7 (2009), and Windows Vista (2007). Windows comes preinstalled on most new PCs, which helps make it the most popular operating system in the world.
For more information, see our tutorials on Windows basics and specific versions of Windows.
macOS
macOS (formerly called OS X) is a suite of operating systems developed by Apple. It comes preinstalled on all Macintosh computers or Macs. Some of the specific versions include Mojave (released in 2018), High Sierra (2017), and Sierra (2016).
According to StatCounter Global Stats, macOS users make up less than 10% of global operating systems – much less than the percentage of Windows users (more than 80%). One reason is that Apple computers tend to be more expensive. However, many people prefer the look and feel of macOS over Windows.
For more information, see our macOS basics tutorial.
Linux
Linux (pronounced LINN-ux) is a family of open-source operating systems, meaning they can be modified and distributed by anyone anywhere in the world. This differs from proprietary software like Windows, which can only be modified by the company that owns it. The advantages of Linux are that it’s free and there are many different distributions – or versions – to choose from.
According to StatCounter Global Stats, Linux users make up less than 2% of global operating systems. However, most servers run Linux because it is relatively easy to customize.
To learn more about the different Linux distributions, visit the Ubuntu, Linux Mint, and Fedora websites or read our Linux resources. For a more comprehensive list, check out MakeUseOf’s list of the best Linux distributions.
Operating systems for mobile devices
The operating systems we’ve talked about so far are designed to run on desktop and laptop computers. Mobile devices such as phones, tablets, and MP3 players are different from desktop and laptop computers, so they run operating systems designed specifically for mobile devices. Examples of mobile operating systems are Apple iOS and Google Android. In the screenshot below you can see how iOS runs on an iPad.
Operating systems for mobile devices are generally not as full-featured as those for desktop and laptop computers, and they cannot run the same software. However, you can still do many things with them such as: For example, watch movies, surf the web, manage your calendar, and play games.
