Computer Software

So you got your first computer, congrats! Now it’s time to explore the wonderful world of software. You’ve probably heard of things like applications, programs, and apps – but what exactly are they and how do they work? Don’t worry, we’ve got you covered. In this article, we’ll walk you through the basics of computer software in simple terms. We’ll start with what software actually is, the main types you need to know about, and how to get software on your computer. Before you know it, you’ll be installing, downloading, and using software like a pro. So boot up your computer and let’s get started – your new world of productivity, creativity, and fun awaits!

What Is Computer Software? Defining This Critical Component

Computer software, also known as just software, is a program or set of programs that run on your computer and allow you to accomplish specific tasks like word processing, surfing the web, or gaming.

The Two Main Types of Software

There are two broad categories of software: system software and application software.

  • System software, which includes the operating system, device drivers, and utilities, manages your computer and the linked devices. You can communicate with your computer and use other programs thanks to the operating system, which may be Windows, macOS, or Chrome OS.
  • Applications, often known as apps, are software packages created to assist you in achieving a particular task, such as editing images, checking email, or streaming music. Popular application software includes items like Microsoft Office, Adobe Photoshop, and Spotify, to name a few.

How Software Works

Software provides code—a set of detailed instructions—that tells your computer what to do. Programming languages like C++ or Python are used to write the code, which is then converted into binary code that can be run by your computer.

In order to enhance your digital experience, new software is always being created. You can help ensure that you have access to new features and security updates by keeping your software updated with the most recent versions. Even though there is an apparently limitless selection of software, knowing the fundamentals can help you make the most of your computer.

Types of Software: System Software vs. Application Software

Computer software comes in two main flavors: system software and application software.

System Software

System software controls the basic functions of your computer and includes:

  • Memory, processes, and storage are managed by operating systems like Windows, MacOS, and Linux. They give you a way to communicate with your computer through a user interface.
  • drivers for hardware that enable communication between your operating system and devices like printers, scanners, and graphics cards. Your OS wouldn’t recognize these components without device drivers.
  • Utility programs that perform maintenance tasks like disk defragmenters, antivirus software, and backup programs.

Application Software

Application software, or “apps,” are programs designed to carry out specific tasks for the end user like:

  1. Word processors, spreadsheets, and presentation software for productivity. Think Microsoft Office or Google Docs.
  2. Web browsers like Chrome and Firefox to access the internet.
  3. Media software to play music, videos, edit photos, and more.
  4. Accounting software for managing finances.
  5. Educational software for learning skills and subjects.

How Software Runs on a Computer: Understanding the Process

Software is what allows computers to run and function. Software contains the instructions that tell the computer what to do.

How Software Works

When you start a program on your computer, the computer’s memory (RAM) receives the software code from the hard disk. The CPU then reads and executes the instructions from the RAM-stored software application. It accomplishes this very quickly, processing millions of instructions per second.

The CPU may need to read and write data to and from your computer’s hard disk or solid state drive while it carries out the instructions. The keyboard, mouse, screen, speakers, and other input/output devices might also need to be used in conjunction with it. The software’s ability to execute different programs on your computer and function is made possible by all of this synchronized action.

The operating system, like Windows, macOS, or Linux, is the most basic kind of software. The operating system controls all the physical parts of your computer and enables you to execute various software applications. On top of the operating system, programs such as web browsers, productivity tools, games, mobile apps, and more are constructed.


This concludes our brief introduction to the various categories of software that power your digital life. Software is what actually powers and controls your computer, including operating systems, programs, browsers, and plugins. You can better comprehend what’s going on behind the scenes by understanding the fundamentals of the software on your devices. And the more information you have, the more your technology may be adjusted to better meet your needs. Software evolves quickly, so to be sure you have the newest features and security fixes, check for updates to your operating system, applications, and browsers. Although it may seem difficult at first, start with the basics and work your way up. Soon enough, you’ll be writing your own programs! Well, maybe not, but at least you’ll have a firm understanding of how the software on your phone and computer actually works.
