What are the operating systems?

Every day, while working with a computer, we do not even suspect that with one keystroke millions of the smallest elements are activated. Thus, we make the computer logic work. We make opening and closing of various programs, listen to music and watch movies. But we do not even think about what operating systems are?

Let's start with statistics. According to research data, Unix (Linux) operating systems are used by about 1% of consumers. Apple OS (MacOS), use about 8%, and finally, the operating system of different versions of Windows, use about 90% of users. But judging by the earlier statistics, users move with short steps from the usual Windows to us, to other operating systems.

Therefore, today we consider what operating systems exist, and analyze the 3 most popular.

Windows 7 operating system

Today, Windows 7 is quite stable and very convenient system to use, and it is easy to agree with this conviction.

Hardware resources - for a 32-bit system, 1 GB is enough. RAM, 128 MB video card. And versions of DirectX 9. You will also be required to have a recording and reading device - a USB connector, or a DVD drive. A prerequisite is the presence of 16 GB. Space on the hard disk.

The performance is quite high, which is good news when using browsers and photoshop at the same time, or something else. Compared with previous versions of OSes, hard disk performance has become stronger, graphics have weakened a little. But the hardware part of it completely compensates. In general, the result is that Windows 7 is still a couple of positions in comparison with Windows XP.

Interface - as the developers say is quite friendly. The desktop is quite amenable to customization, and the system, in general, added a number of tweaks.

Security - much better worked out the errors that can occur during an oversight. Added functions to protect the system from unauthorized access, various firewalls and utilities, protection from installing unauthorized software. But, as before, there is a mass of viruses that can affect and harm the system.

Linux

Most of the users of this OS are enemy camp for Windows users. In many ways, they are not satisfied with the slowness and a bunch of errors that occur in the Windows system.

Hardware requirements - like all similar systems, Linux requirements are pretty minimal. For this system, 512 mb will be fine. RAM, integrated video card and five GB. Hard disk space. You will also need the same USB or DVD input and output. The bit system will work fine on both 64 and 32-bit processors.

Performance - as usual on top. 32-bit system is a guarantee of compatibility and good graphics, and 64-bit system is improved work with data access.

The interface is more than excellent. Surprised by the variety of various adjustments. From this OS, the user needs performance, functionality and staffing, with which Linux calmly copes.

Security and stability - there are practically no viruses on this OS, but all the same, various means of protection are provided in the system. What faults errors, when they occur, the system will simply restart the module in which the error occurred and will continue to work, the user does not even know about it.

Disadvantages include a small amount of software compared to the rest of the OS, and it also requires constant stay on the network so that OS updates can be installed normally.

MacOS

The hardware requirements are quite high, but they are justified. Worth taking care to turn it into stock:

  • Not less than 2GB. RAM.
  • About 16 GB. Hard drive
  • Video card no less than 512 mb.

Performance - depends on the filling of computers, the more powerful it is, the better it will be.

The interface looks amazing. This OS has always been beautiful, which only the desktop is worth. Anything that can come in handy is always at hand, you can customize anything, the system settings are not as extensive, but functional.

Security - thought out at a good level. Here are the built-in antivirus and firewall. It cannot be said that there are no viruses on this OS, but there are quite a few of them.

Stability - amazes with its confidence. If you ask what is the best operating system for this indicator, then I will definitely say MacOS.

Of course, there are a lot of operating systems, but the percentage compared to the above is so scanty that they fade against the background of these giants.

So, to summarize our topic - what operating systems exist. If you need stability and speed from OSes, choose Linux or MacOC, but if you need functionality, stop on Windows.
