Every day, 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 the opening and closing of various programs, listen to music and watch movies. But we don’t even think about what operating systems are?
As the name suggests, there is a client and a server. So, we have a website - this website is running on a server. Therefore, the server provides a web page delivery service. Subsequently, the server delivers the page and thus performs this service. Other server services are listed here.
The latest news in this blog can be tracked. Tasks operating system- basic client-server model. But what is an operating system and how does it work? This article provides short review functioning of the operating system and lists the points that must be observed in case of security.
Let's start with statistics. According to research, Unix (Linux) operating systems are used by about 1% of consumers. The Apple operating system (MacOS) is used by about 8%, and finally, the operating system of various Windows versions used by about 90% of users. But judging by earlier statistics, users are moving in short steps from the usual Windows to other operating systems.
The operating system consists of several programs that are required to work with a computer. The operating system is loaded at boot time after the computer starts. It serves as a basic requirement for all other programs. The most common operating systems.
First, the operating system provides a user interface for working with a computer. We would like to illustrate the tasks of an operating system using the following example: You want to play the latest online game and run installed game on your computer. The game consists of sounds, images, movie sequences and also requires an internet connection. The operating system recognizes various components and starts necessary programs. These programs then send interface information to the operating system, such as playing music, playing a movie, or downloading data from the Internet.
Therefore, today we will look at what operating systems exist and analyze the 3 most popular ones.
Operating system Windows 7
Today, Windows 7 is quite stable and very easy to use, and it's easy to agree with this belief.
Hardware resources - 1 GB is enough for a 32-bit system. random access memory, 128 mb video cards. AND DirectX versions 9. You will also need a recording and reading device - a USB connector, or a DVD drive. A prerequisite is the presence of 16 GB. Hard disk space.
Performance is quite high, which is good news when using both browsers and Photoshop, or something else. Compared with previous versions operating systems, performance hard disk became stronger, slightly weakened graphics. But the hardware makes up for it. In the overall result, it is believed that Windows 7 still lost a couple of positions in comparison with Windows XP.
The interface - as the developers say is quite friendly. The desktop lends itself quite well to settings, and the system, in general, has added a number of adjustments.
Security - errors that may occur during oversight are much better worked out. Added features to protect the system from outside entry, various firewalls and utilities, protection against the installation of third-party software. But, as before, there are a lot of viruses that can affect and harm the system.
linux
Most of the users of this OS are the enemy camp for Windows users. In many ways, they are not happy with the slowness and bunch of errors that occur in the Windows system.
Hardware requirements - as with all such systems, linux requirements are pretty minimal. For this system, 512 MB will do. RAM, integrated video card and five GB. Free hard disk space. You will also need the same USB or DVD input and output. A 32 bit system will work fine on both 64 and 32 bit processors.
Performance is top notch as usual. 32 bit system- a guarantee of software compatibility and good graphics, and 64 bit - improved work with data access.
The interface is more than excellent. It's amazing how many different settings there are. From this OS, the user needs performance, functionality and staffing, which Linux can easily cope with.
Security and stability - there are practically no viruses on this OS, but all the same, the system provides various means of protection. As for errors, if they occur, the system will simply reload the module in which the error occurred and will continue to work, the user will not even know about it.
The disadvantages are the small number software, compared to other operating systems, and also requires a constant presence in the network so that OS updates can be installed normally.
macOS
The hardware requirements are quite high, but they are justified. Make sure you have in stock:
- Not less than 2GB. RAM.
- About 16 GB. hard drive.
- Video card at least 512 MB.
Performance - directly depends on the filling of computers, the more powerful it is, the better the performance will be.
The interface looks amazing. This OS has always been beautiful, what a desktop is worth. Everything that can be useful is always at hand, you can configure anything, the system settings are not so large-scale, but functional.
Security is well thought out. There are 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 - strikes with its confidence. If you ask what is the best operating system, according to this indicator, then I will say MacOS with confidence.
Of course, there are a lot of operating systems, but the percentage compared to the above is so meager that they go out against the background of these giants.
So, let's sum up our topic - what operating systems exist. If you need stability and speed from an operating system, choose Linux or MacOC, if functionality, stop at Windows.
