Software

So the question is "how many types of software are there?" Well there are two main categories of software. Some sources divide software into three categories. Well, this article will explain each type of software in details with examples. There are three types of software: 1.    System Software 2.    Application Software   3.    Utility Software (most of the people include this as a sub-category of application software)                  System Software                                                                                               System software is a collection of one or more programs used to control and coordinate the hardware and other applic...

Applications Software Application software , or simply  applications , are often called productivity programs or end-user programs because they enable the user to complete tasks, such as creating documents, spreadsheets, databases and publications, doing online research, sending email, designing graphics, running businesses, and even playing games! Application software is specific to the task it is designed for and can be as simple as a calculator application or as complex as a word processing application. When you begin creating a document, the word processing software has already set the margins, font style and size, and the line spacing for you. But you can change these settings, and you have many more formatting options available. For example, the word processor application makes it easy to add color, headings, and pictures or delete, copy, move, and change the document's appearance to suit your needs. A  Web browser , or simply  browser , is an application spe...

Software 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, computers would be useless. For example, without your Internet browser, you could not surf the Internet or read this page and without an operating system, the browser could not run on your computer. The picture to the right 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. It should be noted that although software is thought of as a program, it can be anything that runs on a computer. The table below also includes a program column to clarify any software that is not a program. Software ...

Software topics Architecture Users often see things differently from programmers. People who use modern general purpose computers (as opposed to embedded systems, analog computers and supercomputers) usually see three layers of software performing a variety of tasks: platform, application, and user software. Platform software: The Platform includes the firmware, device drivers, an operating system, and typically a graphical user interface which, in total, allow a user to interact with the computer and its peripherals (associated equipment). Platform software often comes bundled with the computer. On a PC one will usually have the ability to change the platform software. Application software: Application software or Applications are what most people think of when they think of software. Typical examples include office suites and video games. Application software is often purchased separately from computer hardware. Sometimes applications are bundled with the computer, but th...

Software At the lowest level,   executable code   consists of   machine language instructions   specific to an individual   processor —typically a   central processing unit   (CPU). A machine language consists of groups of   binary values   signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also (indirectly) cause something to appear on a display of the computer system—a state change which should be visible to the user. The processor carries out the instructions in the order they are provided, unless it is instructed to   "jump" to a different instruction , or is interrupted (by now   multi-core processors   are dominant, where each core can run instructions in order; then, however, each applicatio...
