Take A QuizSometimes 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.

Installing and uninstalling softwareOnce 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 softwareAfter 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 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.
