Computer programs, by definition, a set of instructions and / or data that the computer system will be implemented in a predetermined sequence. software packages come in many different styles and types. This virtual set of software in many forms: games, web browsers, chat rooms, office applications and software packages are a specialty. Despite a number of options for computer software is available in essentially all the same to your computer: data input and output data.

It’s much easier to break the program into four main groups: productivity, programming, entertainment and general computing functions.

Productivity is a shortcut for many software packages such as Excel, Word, PowerPoint, Pages, Numbers, and so on. This is a special type of software intended for use in various environments, as well as users with varying skill and interest sets. There is a ready-made software packages of computer programs and there are custom applications designed for very specific tasks.

Programming languages which software developers use to create software, although they are themselves part of the software, too. The programming language BASIC in C and JAVA are all very common and there is no clear distinction between compiled languages such as C, and many run-time compiled languages such as many variants of BASIC. The difference is that C is usually used to write the program, and then transform that human readable code into a direct reading of a computer system. Many forms of BASIC on the other hand, a marker or mediator file which needs help during the execution engine to compile it on the fly.

Recent trends in computer languages is to create a platform agnostic software packages. JAVA as a vivid example of language that has led this charge with its “write once, run it on any platform” approach. Platform agnostic, computer software will run on different platforms, but they are usually less efficient than compiled software.

Entertainment software has many forms, but the game is usually what comes to mind when discussing the issue of computer programs designed for entertainment. The latest games almost all of the following trends in the Internet connection for multiplayer purposes (some genres, even requires it), and more realistic 3D-graphics.

There is also an incredibly large number of applications that do not necessarily fall under any of the above categories. For example, instant messaging and e-mail programs can be regarded as labor productivity, but they can also be used for entertainment. Antivirus software is another program that virtually every modern computer should be used, but it is not so easy category with its utility lies in prevention and protection, not the material properties used. Thus, the definition of computer software to perform common tasks will be simple: it must be common to the widest part of the computational requirements, and do not necessarily have to be actively used.

The software may be professionally designed for profit, or public works, which are usually free. This is usually called free or open source, if the code is available for public editing.
