Software means computer instructions or data. Anything that can be stored electronically is software, in contrast to storage devices and display devices which are called hardware.

The terms software and hardware are used as both nouns and adjectives. For example, you can say: "The problem lies in the software," meaning that there is a problem with the program or data, not with the computer itself. You can also say: "It's a software problem."

The distinction between software and hardware is sometimes confusing because they are so integrally linked. Clearly, when you purchase a program, you are buying software. But to buy the software, you need to buy the disk (hardware) on which the software is recorded.

Different browsers can be distinguished from each other by the features they present. Modern browsers and Web pages created more recently tend to use many techniques that did not exist in the early days of the Web. As noted earlier, the disputes between browsers caused a rapid and chaotic expansion of own browsers and standards of the World Wide Web.

From the beginning we learn that everything that relates to instructions given to the computer called SOFTWARE and that the set of instructions that makes the computer work call PROGRAM.

Generally the programs need to be installed on the HDD, CD or even floppy disks and many run directly from USB sticks dispensing installation. Good to learn that by calling (open up) a program it is? Loaded? in memory (RAM), and so starts to control specific operations.

DEFINITION
Software logical, is a sequence of instructions to be followed and / or implemented, handling, redirection or modification of a given / or event information. Software is also the name given to the behavior exhibited by this sequence of instructions when executed on a computer or similar machine. Software is also a product and is developed by the Software Engineering, and includes not only the computer program itself, but also manuals and specifications. For financial accounting purposes, the Software is considered a capital goods.

SYSTEM SOFTWARE
Generally divided into Operating Systems Programs and utilities. To start the system. Operations are of great importance because they give us the option to tell the computer what it should do. 
Two well-known examples of our audience are Windows and Linux. Programs are software utilities usually smaller with more specific functions such as: Scan Disk, Backup and more.


APPLICATION SOFTWARE
In this type of software fit all those programs that are used in performing specific tasks. I can cite many examples but the most common are word processors, such as Word, used to work with many different types of texts, issuing labels, and make forms, spreadsheets such as Excel are powerful tools that facilitate calculations so that the hard work of mathematics, making graphics with real data representation is a very good thing for those who need and lastly that many use but do not know the name for sure which are the browsers or browsers, software used for web browsing, among them the best known today are: Windows Internet Explorer, Firefox, Google Chrome, Opera and Safari.


PROGRAMMING LANGUAGES
This aims to develop other programs and systems for general use. Using this type of software a programmer can develop systems such as: Accounting Systems, Business Administration, Inventory Control / Sale / Purchase etc.

SOFTWARE TUTORIALS
Are generally used to inform or teach about a certain subject, often used in training. The concepts transmitted through this software are restricted to what was predicted by a development team of the same.

SOFTWARE DRILLING
Similar to software tutorial, but here the user has greater interactivity through answer questions before they are submitted.

SOFTWARE RESEARCH
In this category fall all the software that allows the location of various information about various subjects. Encyclopedias are usually classified in this category.

SIMULATION SOFTWARE
Generally used for simulations of real life situations. Among the best known are flight simulators and managers of cities, well known in the world youth games, but when we 
think of simulators can err on again only games, today they are widely used in training situations people cases to face in their day-to-day.


GAMES SOFTWARE
Software are usually related to entertainment to provide leisure and fun. They have many interactive features and there are all kinds, ranging from strategies to realistic simulations of many things like races (Need for Speed) up to the same life like Second Life.


OPEN SOFTWARE
Are those that allow the user to produce freedom and creativity, fall into this category those software presentations, databases, and several others.
