This article discusses the differences between system, utility, and application software that can run on a computer. Show
Software is used to control a computer. There are different types of software that can run on a computer: system software, utility software, and application software. Let’s take a closer look at them. 1. System softwareIf you think of software as being in layers, the system software is the bottom layer: it sits between the hardware and the application software. Operating systems like Windows, macOS, Android and iOS are examples of system software. Operating systems are loaded into RAM when the device starts up, and have access to the hard drive. 2. Utility softwareUtility software is part of the system software and performs specific tasks to keep the computer running. Utility software is always running in the background. Examples of utility software are security and optimisation programs. Security programs include anti-virus software that scans and removes viruses. Most computers will include some sort of anti-virus software, but you can add your own. Optimisation programs can include tools for system clean-up, disk defragmentation, and file compression. These tools are typically installed as part of the operating system. They have access to the hard drive to keep it tidy. 3. Application softwareThis is everything else! Anything that is not an operating system or a utility is an application or app. So a word processor, spreadsheet, web browser, and graphics software are all examples of application software, and they can do many specific tasks. You can remove and add applications on your computer using the operating system. Application software like a word processor regularly directs the operating system to load and save files from and to the hard drive. When you are working on a file, it is saved temporarily in the RAM. It is only when you choose to save it that it is written to the hard drive. This is why, if the computer crashes while you’re working on a file, you may lose any changes you didn’t save. Data stored in the RAM is volatile. The data is lost when the RAM loses power. The operating systemApplication software also uses the operating system to talk to the hardware on the computer and to other software. When a web browser wants to load a web page, it is the operating system that controls access to the internet and fetches the information from the web. Similarly, the operating system also provides the application software information about what key is being pressed, and about the mouse: where it is, what it clicked, and where it’s moving on screen. Application software relies heavily on the operating system to do these tasks and send it all this information. Download our open textbooks in different formats to use them in the way that suits you.

What is operating system and utilities?Operating systems control the computer hardware and act as an interface with application programs. Utility software helps to manage, maintain and control computer resources. Examples of utility programs are antivirus software, backup software and disk tools.
Are utilities a type of application software?It is used to support the computer infrastructure - in contrast to application software, which is aimed at directly performing tasks that benefit ordinary users. However, utilities often form part of the application systems.
What is system application and utility software?System Software maintain the system resources and give the path for application software to run. Utility Software refers to software programs that add functionality to computer and help to perform in better way. System Software is a general purpose software.
What type of system is operating system?What are operating systems? An operating system (OS) is a type of software interface between the user and the device hardware. This software allows users to communicate with the device and perform the desired functions.
