      Each hardware component is specialized to perform a set of specific tasks. For example, the sound card is in charge of providing sound to the user, the graphics card takes care of processing the image and sending it to display, the network card is in charge of connecting to the network and the Internet, and so on.

What Is Software?

      Software is a set of machine-readable instructions that direct a computer or device to perform specific operations. Software is not physical like hardware is. It is ephemeral, in the sense that it is anything that can be stored electronically on the hardware of a computer or device.

      There are many types of software, the most important being these two:

      System Software This software is designed to directly operate the hardware of a computer or device. Such software provides all the basic functions that allow users and other software to control the device's hardware. The most common types of system software are the operating system, drivers (which control a specific hardware component), and system utilities (which assist users in the maintenance of their computers).

      Application Software This is specialized software the users can employ to perform certain tasks. For example, Microsoft PowerPoint lets users create presentations. Antivirus software like Norton Antivirus or Kaspersky Antivirus keeps your computer safe from threats and so on. This type of software is also referred to as applications, programs, or apps (when working with mobile devices). In order to function, application software needs to run on top of both the system software and hardware. Applications are either provided by the operating system (for example, Paint is an application offered by Windows) or installed by users on top of the operating system.
