Operating System Available on the PC
WINDOWS (MICROSOFT WINDOWS)
Mircosoft Windows or commonly referred to as Windows is an SO developed by Microsoft Corporation that uses an interface based on Graphical User Interface (GUI) or graphical interface.
At first Windows started with the Microsoft Disk Operating System (Ms-Dos), which was an operating system based on text and Command-Line interpreters.
The first version of Windows, Windows Graphic Environment 1.0 is a software that works on 16-Bit architecture and is not an Operating System and runs on MS-DOS, so to run it requires MS-DOS. MS-DOS itself is actually made on Seattle Computer Products computer company and only after that was recruited by Microsoft who then purchased a license.
After developing into Windows 1.0 in the first version of SO (operating system) in the world based on Graphical User Interface (GUI) and supports Multi-Tasking or that can do a lot of work simultaneously. After that Windows 1.0 developed into Windows 2.0, Windows 2.0 is based on GUI and supports the use of VGA (Video GraphicsArray) and also supports Multi-Tasking. Windows 2.0 also supports the use of the Intel 80286 Processor where the Intel 80286 Processor is the first Processor with the ability to protect the memory area.
Which then continued with the generation of Windows 3.0 where Windows 3.0 has the same capabilities as the previous Windows and there is an added value added SVGA or XGA graphics support and also a better icon.
In that era, Microsoft also provided a Software Development kit (SDK), so that software developers can continue to develop applications / programs to be able to run on Windows 3.0. Windows 3.0 also introduces the Virtual Device Driver (VXD) which can function to minimize dependency on each driver on certain hardware.
Windows 3.0 then evolved into Windows 3.1 which was introduced with Multimedia features and True Type Fonts as well as making it easier for End-Users because of the Drag and Drop feature and finally Windows version 3 developed into an Operating System that was familiar with NetWorking (Windows 3.11).
After developing for a long time Microsoft finally introduced a 16-Bit / 32-Bit hybrid Operating System known as Windows 95. Many changes from previous versions of Windows, namely: Windows 95 has a more attractive and attractive GUI, supports Plug and Play, supports naming long, has several facilities such as: integrated browser and Windows Explorer to explore Windows. In addition, Windows 95 has features for power management (APM) and the introduction of Client-Server.
The next generation of Windows 95 is Windows 98 where Windows 98 already supports AGP-based VGA, and supports compact storage media such as USB, the introduction of NAT to share Internet connections and the Windows Driver Model replaces the Virtual Device Driver with.
There are also some additional features in the form of Internet Explorer version 5 and Microsoft Office applications. Windows 98 also has the abilities to play games and run Multimedia applications.
The next development is Windows ME, the added value of Windows ME besides the graphics support transition from 16-Bit to 32-Bit and in the era of Windows ME many home users already use it. Windows ME was eventually replaced with Windows NT which already supports x86 (80x86) architecture, Intel IA64 and AMD64 (x64) and supports 32-Bit graphics.
Windows NT was actually built from the development of IBM OS / 2 and Windows NT is also widely used in computer networks. Windows NT also introduces the NTFS File System which is better than FAT or FAT-32.
Then Windows NT developed into Windows 2000, there were many additional features including: Active Directory, Image Preview, Internet Explorer v6 Browser, DirectX and Open GL, Plug and Play and Windows Driver Model for better performance.
After the generation of Windows NT came the Windows XP that offers many changes, has many features and performance that is increasingly increasing. It can be said that Windows XP is the best-selling Windows and is in demand by PC users and mobile PC devices (Mobile).
Along with the need for networking, Microsoft Corporation issued an SO that concentrates on networking, namely: Windows Server 2003. You could say Windows Server 2003 is the reincarnation of Windows NT.
Lots of features offered on Windows Server 2003, one of which is the introduction of the .Net platform. Also introduced are Domain Controller Server features, PKI (Public Key Infrastructure) Servers, Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), Windows Internet Name Services (WINS), Microsoft IIS, and others.
Microsoft also continues the development of the Operating System with Windows Vista (Longhorn), Windows Vista is a revolution of Windows XP. Windows Vista itself prefers the interface (interface) or graphical appearance of the interface compared to existing performance, evidenced by the presence of features such as: AERO and Sidebar and so on.
Windows Vista also offers better security compared to Windows XP, because in Windows Vista introduced, Windows Defender, Windows Firewall with Advanced Security, BitLocker Drive Encryption, ASLR, Parental Control, User Account Control (UAC) ,.
Windows Vista also introduces IPv6, the latest version of DirectX, and 64-Bit architecture. The next development was the transition from Windows Server 2003 to Windows Home Server which was intended as a File Server for the home.
Windows Server also introduces several technologies, namely: Headless Operation (the server does not need a monitor or keyboard to manage the device), remote control, computer health monitoring, sharing and streaming.
The next generation is marked by the merging of Windows Server with BitLocker Drive Encryption, ASLR, which is Windows Server 2008. Windows Server and Windows Vista Features are combined into one to increase the security and comfort of End-Users.
Furthermore, Windows Server 2008 developed into Windows Server 2008 R2. The last version of the Operating System made by Windows was Windows 7, Windows 7 was released to replace the shortcomings in Windows XP and Windows Vista plus value.
It can be said if Windows 7 is a fusion of Windows XP and Windows Vista, unlike Windows Vista, Windows 7 has a performance that is certainly better than Windows Vista.
