Differences between Free Software and Commercial Software

Differentiate the hardware from software is not difficult. In the first classes of any school where it teaches computing, it quickly learns the difference between the two.

Nevertheless, the concept of software is more complicated to understand, despite being widely used and often illegally. An important point to differentiate are the concepts of Free Software and Commercial Software.

Free and commercial software

Free software

The Free software are those software that are under a free license, whereby the use, modification and distribution are permitted at all. The main free software licenses are GPL and LGPL.

The first, intended for users who may incorporate modifications or free software can add to a job, which should make it available also with the same license. The second It is more permissive, and it can be used even for commercial purposes.

Free and commercial software

Free software does not necessarily mean it is free of charge, this is an important point to consider, many free software can be sold separated or incorporated to another software to selling like consulting or related services, for example.

Examples of Free Software:

  • Linux Operating System
  • Java and PHP languages
  • MySQL Database
  • Open Office Suite

Commercial software

Commercial Software or proprietary software is those software that has an owner of its copyrights, and their use is allowed through a business license and most of the time paid.

Commercial software is no different from any other product commercially, only considering that still paying for software will be receiving only license or right to use and will not be buying the software itself.

Free and commercial software

The most important market Commercial Software companies are Microsoft, Google Adobe, Corel, Autodesk and Apple, among many others.

Examples of Commercial Software:

  • Windows operating system
  • Microsoft Office Suite (Word, Excel, Power Point)
  • Adobe Photoshop, an image processing software very popular
  • Suite development for Dreamweaver, Flash and Fireworks
  • Software for vector graphic design Corel Draw

Which one to use? Free Software or Commercial Software?

Using Free Software and Commercial Software is a decision of each company or person. The price, license, business model, support and functionality are some points that should be considered.

Free and commercial software

Many individuals and companies make joint use of Free Software and Commercial Software. It is a good strategy because this way you can exploit the best of both.

What are the differences between Windows and Linux?

Who of us has not ever heard about the existing battle between Windows and Linux users? At this point in the circumstances surely no one can deny that both sides have their reasons, and of course, believe that the operating system they use is the best.

Unfortunately, this difference of opinion is expressed as a kind of contest without real possibility of peace, all because of fanaticism without reason, which of course leaves the neutral user without deep knowledge of the subject, with the impossibility of knowing what the operating system that best fits your specific needs.

Differences between Windows & Linux

There is really no doubt that Windows is the operating system currently most widely used worldwide, but over the months, Linux is increasingly taking preponderance. While both operating systems offer deep design differences, they share the same philosophy: be easy to use and provide the user with all necessary tools to carry out its tasks.

Windows vs Linux: Hardware and software

It is a myth that Linux is an operating system for connoisseurs, the efforts made by companies like Canonical, makers of Ubuntu, the most widely used Linux distribution, are huge, all focused for the user to get exactly what you want without mechanisms complicated.

This was so many years ago, but now things have changed. Linux is at the same level of usability Windows, where everything is materialized in a few clicks. This is not bad, is basically what need a user that to have to spend much time in front of the computer screen.

Differences between Windows & Linux

Windows and Linux apps

Where Windows shines is in the number of applications available for the platform. Not that there is not much variety of applications in the Linux environment, but let’s face it, for every Linux application for a particular task, there are 100 for Windows, giving us a better margin of choice. One of the best places to download thousands of applications for Windows is CNET Downloads.

Differences between Windows & Linux

Another point where perhaps Windows is a better choice for us is whether we are professionals in a specific field such as graphic design, video editing or other very specific task, but if ours is the writing, trading or other activities where not required special applications, on Linux we can find amazing tools like OpenOffice or GNUCash, which will satisfy our needs perfectly.

Photoshop, games and other specific apps in Linux and Windows

Although many Linux fans will find that the following declaration is almost an offense, the fact is that Gimp, an excellent tool for image manipulation, is light years behind in terms of design and features from Adobe Photoshop. Same with applications like Cinelerra or Inkscape, all very good, but its implementation in the professional field is almost non-viable. Similarly happens with games.

Differences between Windows & Linux

However, for the basic user, which only requires a few tools like an image editor, a text editor and some other things, Linux, being free and very stable, it is a very interesting option, and best of all it is that exist versions, called distributions, specifically designed to be used on older computers or with limited resources.

Differences between Windows & Linux

Not so with Windows, since the latest version of the operating system requires considerable resources, and older versions such as Windows XP, which could best work on old equipment no longer supported or updated, whereby use of this type of OS it can be quite dangerous today.

Printers and video cards

Windows is very friendly with respect to the installation of devices. In contrast, although a vast majority of times we will not have trouble installing printers, video cards or other peripherals, Linux is sometimes a bit complicated in that sense, but it is noteworthy that this is also due to reluctance of some manufacturers to develop drivers for Linux of your devices.

Differences between Windows & Linux

Windows vs Linux: Virus and Security

Windows is widely recognized by the large number of viruses and malware developed for damaging its structure, but over the years this image is increasingly far from reality. Microsoft, thanks to the profound changes, constant updates in the system and in the code and changing the way how users use permits system has achieved greatly minimize the vulnerabilities who once were responsible for the destruction of hundreds of terabytes of information. And if we add a good antivirus system like Microsoft Security or Avast! We not have to worry about anything.

Much has been said about that Linux is invincible in relation to the virus, and this is very true. The system file permissions of the operating system make it an impregnable fortress.

Differences between Windows & Linux

Nevertheless, the fundamental fact for which Linux is not so exposed to attack as Windows is simple: Do not exist so many Linux users, at least in the home environment or small office, so it is not profitable to develop specific virus for this platform, at least for the moment.


Both operating systems deliver what they promise, if we consider the issues raised above, these operating systems can be very useful in our work.

Obviously one of the biggest differences between Windows and Linux is that the Penguin SO is absolutely free, against the hundreds of dollars it costs a Windows license, and it is paramount that the user must keep in mind before making any step.

With Linux we can do everything we are used to doing with Windows, even a lot of software available for Windows has developed a version of it for Linux.

But to know in depth which is the operating system that best suits us nothing better than to try it for yourself each of its characteristics, ponder about the type of computer we have and the work we do every day, and from there, draw conclusions.
