Components of Centos and Windows Operating System
CentOS, which stands for the Community Enterprise Operating System, is a distribution of the Linux operating system based on Red Hat Enterprise Linux. And is currently the most popular Linux distribution for web servers.
CentOS uses the Red Hat source code base to create a product similar to RHEL. Unlike RHEL however, CentOS does not require a paid subscription. It is open source.
CentOS features the characteristics that make RHEL so valuable to companies:
Stability: CentOS is continually advancing to give the ideal stage to the most recent programming. Regardless of whether more applications are good, is constantly considered. Future improvement steps are constantly done so that the solidness of dynamic parts is likewise ensured. The framework is intense with regards to virtualization (on a Kernel-based Virtual Machine, KVM) and high in accessibility, which is the reason the dissemination additionally establishes a decent connection while working virtualization and Cloud servers.
Security: The issue of security is currently more critical than any time in recent memory, which is the reason CentOS as an endeavor arrangement with RHEL foundation is an amazing decision. Red Hat's fundamental source code is as of now at an abnormal state (the extent that security is concerned), because of proactive helplessness location by the security group of the American programming organization. Likewise, security and mistake checks are the principal need for each CentOS refresh and in the mix of new projects. The Linux circulation likewise underpins the part expansion SELinux (Security-Enhanced Linux), an open source item that starts from the coordinated effort between Red Hat and the NSA. The program executes approval checks for the utilization of PC assets and consequently secures against unapproved get to.
Maintenance and support cycles: since the main CentOS version, there have been both little and expansive releases that are firmly connected to RHEL's comparing distributions. The advancement group assesses a time of 2 to about a month and a half (or a couple of hours for little updates) for the procedure of code adjustment. The rendition numbers are essentially kept (e.g. RHEL 6.2 à CentOS 6.2). Since form 7, a period stamp has been included, which demonstrates the arrival of the fundamental code. Adaptation 7.0-1406 demonstrates, for instance, that the source was discharged in June 2014. Notwithstanding the forming, CentOS has likewise embraced rules for the subsequent period: up to 7 years for general help and up to 10 long stretches of giving security refreshes (up to rendition 5.0, it was up to 4 and 7 years).
Software and application:
The software and the application for this open source OS can be updated automatically to get the latest version for each application installed on Centos. Or else get it updated manually by selecting which application to update. Furthermore, the Centos uses command lines either update and to also install programs into Centos.
The current CentOS version 7.0 is based on the Linux kernel 3.10.0 including the security enhancement SELinux already implemented and has GCC (GNU Compiler Collection) implemented. This collection contains compilers for the most important programming languages: C, C ++, and Java. The Linux distribution also supports hyper-threading (splitting a processor into two virtual processors to increase performance), Plug and Play, Bluetooth, and version 6 of the Internet Protocol (IPv6). Compatibility libraries are available for the older CentOS 5 and 6 versions. The standard distribution package also includes the following software components:
Web server: httpd 2.4.6 (Apache)
LAN manager: Samba-4.1.x
Database: MariaDB 5.5.x, PostgreSQL 9.2.x
Scripting language: PHP 5.4, Python 2.7, Perl 5.16.3
Desktop interface: Gnome 3.14, KDE 4.14
Display server: X.org 7.7
E-mail client: Evolution 3.12, Thunderbird 45
Internet browser: Firefox 45
Office suite: LibreOffice 4.3.7
The Centos is also user friendly for the user (people) to use have the luxury of being the most widely-used operating system in the world. As such, new users have to re-learn how to perform simple tasks on an unfamiliar and often complicated system, which can be off putting for the casual user.
However, programs usually run on the free equivalent, they often lack the certification and support from their respective vendors, which is why they are not always guaranteed to work properly with CentOS.
Windows OS can be called many things, but ‘lightweight and speedy’ is not one of them. Windows nowadays is simple, familiar, and guaranteed to be compatible with virtually all software; for busy companies, that could well be more valuable in the long run.
Scalability- Scalability is the ability to fully utilize available processing power on a multiprocessor system. It also depends on what the user who wants to get the windows OS that will have the bigger amount of storage hard drive or a less storage Hard drive.
Maintenance- Keeping the windows to be in good health is that it must be up to date with latest version, make sure it has anti-virus on installed or else turn on windows defender as default.
Software and application of this OS is a closed which means that for Windows you will have to pay for the license of the OS and that you will keep it up to date to the latest version of windows.
Also can download software via internet and installing it straight away.
As mentioned mostly the users nowadays using windows are much easier and simple also with its features. The primary features of Windows are:
Start Menu – The Start Menu provides the primary access point for programs and applications on your ThinkPad.
Taskbar and Notification Area – The Taskbar contains 3 main components, the Start button, the Task/Quicklaunch bar and the System Notification Area.
Windows Snipping Tool – Windows 7 includes an application to capture, save and share “snipped” images from your desktop.
Displaying to a External Monitor or Projector – The ThinkPad is equipped with one or more external display connectors so that you may connect to an external monitor or the multimedia projector.
Using Local Area Networks (LAN/WiFi) – The ThinkPad is configured to access both wired and wireless network resources.
Windows Explorer Favorites – File system favorites are quick links to specific directories (folders) located on your hard drive.
Windows Explorer Libraries – Libraries are an easy way to collect and track documents on your computer that are related to one another but are not necessarily located in the same directories (folders).
Evolution of Linux Centos
entos, which remains for C ommunity En terprise O perating S ystem, is the consequence of a gathering of open source benefactors and clients cooperating to create Linux arrangements that are unreservedly accessible to clients who don't require a lot of business support to accomplish their objectives. Centos committed servers were composed in view of Red Hat's item, Red Hat Enterprise Linux.
Be that as it may, Red Hat releases its source code for its item under the terms of the GNU General Public License, so the utilization of the code for the formation of the Centos Linux dissemination is an altogether substantial and adequate practice. The circulation of Centos items totally agrees to Red Hat's redistribution arrangement. The Centos server is relatively indistinguishable to the Red Hat item with the exception of that it is changed to expel all Red Hat marking and work of art. Centos and its Linux arrangements are not at all subsidiary with or upheld by Red Hat, Inc.
Linux was propelled later than Windows, in 1991. It was made by Finnish understudy Linus Torvalds, who needed to make a free working framework part that anybody could utilize. Despite the fact that it's still viewed as an exceptionally stripped down working framework, without a graphical interface like Windows, it has all things considered developed significantly, with only a couple of lines of source code in its unique discharge to where it stands today, containing in excess of 23.3 million lines of source code.
Evolution of Windows
The first version of Windows, 1.0, was released in 1985, two years after Bill Gates founded Microsoft. It ran from MS-DOS, which launched Program Manager to run applications.
Two years after the first version of Windows was launched, Gates rolled out the next version of the operating system, Windows 2.0, with a third iteration, Microsoft Windows/386 launching in the same year. By the time Windows 1995 launched, Windows had evolved into its own operating system, making use of a 16-bit DOS-based kernel and a 32-bit user space to make for a more robust user experience.
In fact, Windows 1995 is the basis of what Windows 10 has become, introducing many of the features we recognise today, including the Start menu, the taskbar and Windows Explorer, which has now evolved to become File Explorer. Windows ME, launched in 2000, was the final DOS-based iteration of Windows.
The platform has undergone a swift evolution since it migrated away from DOS, with some versions proving much more successful than others.
