Delivering Innovation

Computer software refers to a program (or a group of programs) that gives the computer instructions on what to do and how to operate. Software programs can provide one main task or multiple main tasks.

As an example, a program designed to edit digital photos has one key task (ie, allow photo editing); naturally, it would have numerous sub-tasks (ie red-eye removal, color correction functions, resizing, and cropping/cropping an image).

On the other hand, a computer’s operating system (a complex piece of software that basically drives and runs the entire computer) would carry out many main tasks, for example handling input and output (i.e. the user typing a keyword or incoming audio). without speakers), memory allocation, management of computer hardware components (these are the electrical components that power a computer), and much more.

The software can be grouped into roughly two groups: software application Y systems software. Essentially, software that facilitates only one main task (for example, photo editing software as in the example above) would be counted as application software. This is in contrast to system software, which refers to complex, multitasking programs that help run the entire system, much like an operating system.

These two main groups of software are discussed in more detail below:

Application software

This is software that is installed on an operating system (see “Systems Software” below for more information). As mentioned above, this type of software tends to perform only one main task. Another example of application software would be a web browser – this is the program you are probably using right now to view this article. Examples of a browser include Internet Explorer, Google Chrome, and Mozilla Firefox. In short, its main task/function is to make it easy for you to surf the Internet.

Other types of application software are as follows:

  • word processing – This type of software allows you to write documents and letters. Examples include Microsoft Office Word and Open Office.
  • antivirus software – this type of software helps protect your computer system from malicious threats like viruses and malware. Examples include Norton Antivirus, Kaspersky Antivirus, and AVG Antivirus.
  • photo editing – this type of software can be used to edit and manipulate photos and other digital images in various ways. Examples include Paint.net, Corel PaintShop Pro, and Adobe Photoshop.

systems software

This type of software is fairly accurately described as being the very core of any computer system. Without systems software, a computer couldn’t really function. In short, it manages all aspects of a computer system, from how hardware interacts with software (‘drivers’) to providing the user with an interface and platform to interact with the system (‘operating system’). Tea operating system – or ‘OS’ – is the software that loads after you turn on the computer. This is where all the application software is installed. Examples of an operating system include Microsoft Windows (XP, Vista, 7, etc.), Linux (Ubuntu, CentOS), and Apple Mac OS X.

Other types of system software include device units (these make the hardware components work properly with the computer software and system) and utilities (These are also called ‘utility tools’ and help to monitor, maintain, check and analyze different parts of a computer, such as ‘Task Manager’ and ‘Disk Defragmentation in Windows operating systems).
