Operating Systems


The operating system is the software that makes your computer operable and generally provides you with a graphical interface with which you can work.

In principle, this interface is not that different whether you are using Windows, Linux / Unix or Apple. Basically it always consists of a bar in which you can see your open programs and that with a start menu for starting your programs.

Your programs run in windows that you can enlarge, reduce or close with the mouse. There is not much that can be done differently. The differences are more in the technical basis and in the configurability and flexibility.

Microsoft Windows

We have followed Microsoft's path for over 30 years, from MS-DOS to Windows 3.1 as the first usable window interface, Windows NT as the first non-DOS-based system to today's Windows 10. MS Windows has long been the most widespread Operating system on the PC.

With Windows 10, Microsoft's concept changed to "Windows as a Service", Windows as a service. This shifted control of the user's computer - and the data on it - to a large extent to Microsoft. From the point of view of data protection and data security, this is a very worrying development.

Still, Windows takes an undeniable advantage of the fact that peripherals - printers, scanners, and other devices - are primarily designed for Windows and can therefore be used indiscriminately under Windows.


Linux is a further development of the UNIX operating system. UNIX is practically the grandfather of all computer operating systems. The first graphical user interface with windows and mouse control was developed for UNIX. In addition to Linux, Apple's Mac OS or OS X and the (free) BSD systems are direct UNIX derivatives.

Linux has long been the dominant server operating system. There are various distributions, some of which are more or less experimental and focus on using the latest developments and program versions, while others - like Debian - focus on the greatest possible stability.

On a Linux system there is a strict separation between the operating system and the graphical user interface. Linux users can choose from a large number of so-called "desktops": Mate, Cinnamon, Gnome, the KDE.

In contrast to Windows, you download programs for your Linux distribution using a so-called package manager. These packages are provided by the developers of a distribution and are signed by them. This largely eliminates the likelihood of a program installing malware.

Installation on a desktop computer or laptop is no longer a problem with the well-known distributions, they install themselves automatically and work like Windows out of the box. They also offer advantages through their update system, which, unlike Windows, usually does not require a restart. Linux updates run at the same time and you can continue to work without worrying, there are no waiting times after a restart and errors and security holes are fixed within a few days, there is no waiting until a "patch day".

However, there are still problems with the driver support for printers, scanners and the like. While keyboard, mouse and screen are not a problem, one should look for the existence of Linux drivers when purchasing other devices.

OpenBSD, FreeBSD and derivatives

The BSD systems are conceptually similar to Linux, but from a technical point of view they are more of a conventional Unix. Software and updates are compiled from the source code on the computer - which runs automatically, remains completely hidden from the user and does not require any intervention on his part.

However, it is even more important to pay attention to compatible hardware than under Linux, already when purchasing the computer. You get a stable and very secure operating system for this.

If the security requirements are very high, we recommend TrueOS for server and desktop with data encryption, Remote Management SysAdm and OpenZFS file system with rollback and software raid functions out of the box.

We would be happy to put together your Linux or BSD computer for you.

Selection of compatible hardware, installation of operating system and drivers for printers and scanners at affordable prices.
