What is the definition of computer software?

The term "software" is a recently developed. In his essay from 1935, "Computer Numbers with a request to the decision problem," Alan Turing proposed for the first time and laid the basis for most modern software. In 1958, the first use of the software, the word was invented by John W. Tukey in an article in American Mathematical Monthly.

Today, the term "Software" write rules or codes, as well as documents on the functioning of a computer system, the read / write memory will be registered. The "soft" software for numerous products and technologies are developed, using various methods such as programming and scripting languages. The term "software" is broad and can have different types of devices such as the functioning of modern devices such as cars, TVs, toasters, etc.

Software are the descriptions of the body, which the computer can perform. It can not be physically touched. For example, most computers are equipped with software already installed. The software is also available on CD, if the user has the CD-ROM on the hard drive and follow the instructions for installation. In addition to downloading the software you find on the website such as Microsoft. Computer software are primarily a series of instructions that a computer, how to get a job. For example, Microsoft Word is an example of software. In addition, the website of technologies such as HTML, PHP, ASP.NET, XML, and are examples of the software of the computer.

The software can be divided into two broad categories: software, operating system and application software.

Operating Systems (0 / A): This system consists of the basic functions that computers perform. An example would be the movement on the screen shows a mouse pointer, the user moves the mouse. Examples of the following operating systems: Windows Vista, Windows XP, Mac, Linux and Unix.

Software applications: These are applications running on the computer to work. Software application used to perform the functions that are not simple functioning of the computer system. This may be the voice, play or store music, videos, games to play videos - and much more. Other examples are the software applications to access the Internet and the printing of documents. Application software is software that indirectly through interaction with the computer.

System Software is a software that directly with the hardware. For example, the motherboard, processor, keyboard, mouse, printer - and much more. Software system is responsible for the supervision, integration and management of the individual components of a computer system.

The software consists of machine language, which is mainly of groups of binary codes, the instructions of the processor, for a processor. It is at the highest level in the programming language and then interpreted into machine language code. The software can also be written assembler language is a mnemonic representation of a machine language with a natural language alphabet.

The term has focused on software for the calculation of the theories and forms of the pioneers in the field of mathematics. It is easy to see how the technology has rapidly evolved into the incredible complexity of the calculations and we see today.
