Operating Systems

Installations

We have been installing and maintaining Windows, Linux, macOS (Mac OS) and IBM operating systems for the past 25 years. However, a shift towards Linux is becoming more and more apparent.

Our emphasis was for many years, as widely accepted and preferred, on Windows systems. Only later OS X (now macOS) and Linux came along.

However, after all this time and many experiences, it can now be concluded that the tendencies have shifted.
On the one hand, Android (a GNU/Linux-based operating system optimized for smartphones) has conquered the market and holds a share of 80%. On the other hand, the strategies and attitudes of the manufacturers of operating systems have changed significantly.

Optimization

Optimization of server software, as well as single-user systems is an absolute must in Windows operating systems. This is because the systems have the characteristic of polluting themselves through normal daily use and consequently becoming slower and slower.

There are various well-proven forms and levels of optimization that we use and thereby increase the performance again.
The software cleaning and tuning tools offered on the market are for the most part mere window dressing and usually do not keep what they promise.

With macOS the necessary cleaning work is much less since we are dealing with a UNIX system. However, some maintenance is still required to keep it in a good condition.

If you take Linux systems, they score with exceptionally low maintenance, while still maintaining a consistently high speed. Also, all the necessary tools are already included in the system and do not have to be purchased additionally.
Linux is also a kind of UNIX, however the concept has been implemented more intelligently. This rewards one with stability, security, and high system speed, even on weaker, older hardware.

Maintenance

If one compares the maintenance cost curve of all the systems presented and installed by us, one finds that the cost peak are the Windows systems, with a significant decline at the Apple-oriented systems, and with a barely noteworthy curve at  Linux-based systems.

If one thinks cost-consciously, one can also take into account that the acquisition costs show a similar curve as the maintenance costs, but here the peak is at macOS systems, followed by Windows, and lowest with Linux.
This is simply because a new investment in the computer area can be postponed if one installs Linux and discovers that the previously slow Windows computer has suddenly become much faster.

Security

A still important, although today slightly undermined, topic is the differing security and virus frequency of the various systems.

In this area, the curve is reversed. At the very top of security is Linux, then slightly lower macOS, and then a sharp drop down towards Windows. There is hardly a system with as many security gaps as Windows. The firewall is unfortunately not adequate.

Likewise, the virus frequency is highest in Windows, with a significantly lower incidence in macOS, and almost negligible in Linux. There are only a few rootkits that could occur, which can be removed quickly using the scanner that can be installed as an on-board tool.

The greatest effort in virus removal arises with Windows systems.
And a fatal side effect occurs with macOS: one thinks one is safe, the system becomes infected, and one does not notice it right away.
