What is another name for a collection of data or computer instructions that tell the computer how do you work?

Updated: 08/16/2021 by

Sometimes abbreviated as SW and S/W, software is a collection of instructions that enable the user to interact with a computer, its hardware, or perform tasks. Without software, most computers would be useless. For example, without your Internet browser software, you could not surf the Internet or read this page. Without an operating system, the browser could not run on your computer. The picture shows a Microsoft Excel box, an example of a spreadsheet software program.

Examples and types of software

Below is a list of the different kinds of software a computer may have installed with examples of related programs. Click any of the links below for additional information.

Although application software is thought of as a program, it can be anything that runs on a computer. The following table also has a "Program?" column to clarify any software that's not a program.

Tip

See our program definition for additional examples of computer programs.

How do you get software?

Software can be purchased at a retail computer store or online and come in a box containing all the disks (floppy diskette, CD, DVD, or Blu-ray), manuals, warranty, and other documentation.

Software can also be downloaded to a computer over the Internet. Once downloaded, setup files are run to start the installation process on your computer.

Free software

There are also a lot of free software programs available that are separated into the following categories.

• Shareware or trial software is software that gives you a few days to try the software before you have to buy the program. After the trial time expires, you'll be asked to enter a code or register the product before you can continue to use it.
• Freeware is completely free software that never requires payment, as long as it is not modified.
• Open source software is similar to freeware. Not only is the program free, but the source code is also available to everyone.
• Bundle ware is software bundled with new computers and hardware.

How do you use computer software?

Once the software is installed on the computer hard drive, the program can be used at any time. On a Windows computer, a program icon is added to the Start menu or Start screen, depending on your version of Windows.

How to maintain software

After the software is installed on your computer, it may need to be updated to fix any found errors. Updating a program can be done using software patches. Once updates are installed, any problems that may have been experienced in the program will no longer occur.

How is software created and how does it work?

A computer programmer (or several computer programmers) write the instructions using a programming language, defining how the software should operate on structured data. The program may then be interpreted, or compiled into machine code.

When I save a document, is that file also considered software?

When you create or edit a file using software — a Microsoft Word document, for instance, or a Photoshop image — that file is considered a software "resource" or "asset." However, the file itself is not considered "software" even though it is an essential part of what your software is doing.

What was the first piece of computer software?

The first software program that was held in electronic memory was credited to and written by Tom Kilburn. The program calculated the highest factor of the integer 218 = 262,144, and was successfully executed on June 21, 1948, at the University of Manchester, England. The computer that held that program was called the SSEM (Small Scale Experimental Machine), otherwise known as the "Manchester Baby." This event is widely celebrated as the birth of software.

How expensive is software?

The price for certain applications can vary widely. For example, there are games on Steam that go for less than $5 and advanced programs, such as Cinema 4D Studio, can cost more than $3,500.
