What is CentOS?

Operating systems are one of the most important parts of information technologies. Operating systems, which determine the operating performance of computers and their compatibility with other hardware, are the tools that enable basic features to become functional. Operating systems with different software and interface types also have distributions within themselves. CentOS, one of the distributions of the Linux operating system, can easily be cited as an example.

The types of operating systems and distribution types serve different usage purposes. For example, there are softwares and interfaces that make daily use easier, as well as software and interfaces that will make the work of informatics specialists functional. CentOS, one of the sub-operating systems of Linux, was produced and put into use by an independent group of software developers.

Different distributions of operating systems that manage hardware resources as well as provide the connection between the services used for different resources and the device contain basic software differences. In a structure where the application codes are largely executed by the hardware, the software differences of the sub-operating systems can be counted among the factors that make it easier to use and functional.

Before elaborating the subject in terms of Linux and CentOS, it should be noted that CentOS is an operating system generally used by IT experts on web servers. This means that the software features and interface of CentOS can be expressed as addressing different needs than basic usage. Because the operating systems used in web servers differ in certain technical areas.

CentOS is an operating system distributed by Red Hat. It is based on Red Hat Enterprise Linux (RHEL) source code. CentOS, which is compatible with the distribution of the Linux operating system, has been developed by independent developers. CentOS stands for The Community ENTerprise Operating System. The release date of this Linux distribution by Red Hat company is May 14, 2004.

The hardware requirements of CentOS, an operating system, are largely the same as Red Hat Enterprise Linux. This is because CentOS's distribution is linked to Linux. This operating system works fully compatible with Intel x88 (32 bit), Intel Itanium, Advanced Micro Devices AMD64, Intel EM64T (64 bit), PowePC / 32 (Apple) and IBM Mainframe.

CentOS, which is among the first choices of information specialists due to its high performance in web servers, works seamlessly with processors of X86 PAE and x86-64 type architecture. Users do not have to pay any fees to use CentOS. If you need support while using the operating system, you can easily request many different help from the website of the community.

The most important point that distinguishes CentOS from other Linux distributions is its long-term support.
