TYPE TYPE OPERATING SYSTEMS / OPERATING SYSTEM

Operating System is a liaison / interface between the user of the computer by the computer hardware. Before there was the system operating, people only use a computer using analog signals and digital signals. Along with the development of knowledge and technology, there are now a variety of operating systems with the advantages of each. To better understand the operating system then you should need to know first some basic concepts regarding the operating system itself. General understanding of the operating system is managing all the resources contained in the computer system and provides a set of services (system calls) to the wearer making it easier and freshen the application and use of resources computer system

1.       DOS

• DOS program displays a more "realistic" than windows because some of the windows command itself adapted from DOS (eg virus command to hide attributes).

• DOS is still using the Command Line Interface.
• Windows is now (NT Tech) is not so compatible with DOS programs, for example when running the DOS program without passing CMD, immediately shut down the same Windowsnya.

• Graphic display is more attractive because based graphical user interface (GUI).
• Users will be easier to use without the need to memorize.
• With SO is a data can be used together and can be moved from one application to another with ease.
• Multithreading facilities and pre-emptive multitasking so that more responsive multitasking performance. With this facility can be run multiple programs simultaneously.
• Can connect one computer to another computer using the modem.
• Powered by the industry-standard Plug and Play which can help to avoid difficulties when adding new hardware.
• Many software products that support these operating systems.

• Price lisenci expensive.
• Vulnerable to viruses and worms.
• No security system is tough, unless MS Windows 2000 and XP, the MS Windows 9.x/Me.
• On MS Windows (except MS Windows 2000 better than Win 9.x/Me) more and more applications are installed, it will most likely happen crashed.
• Large disk space required.
• Requires high-speed processor.
• Require ongoing care and procedures were in accordance with existing guidance while using it.

• Portability, UNIX system easily adaptable to other computer systems
• Multiuser, number of users (user) can use the system simultaneously and share penggunaa sources such as printers, disk, etc..
• Multitasking, allows one to perform several tasks at the same time
• Hierarchical file system, the organization of information or data in a form that is easy to remember and accessible.
• Stable file system for database, server Internet, Intranet, file-server, Internet-client Java development. 
• Famous stability and better performance compared to Windows NT.
• Already available version of the Unix operating system "virtually" free.

• Visually unappealing.
• Large memory used.
• Still not many big games that are willing to run on this platform.
• Some hardware is difficult to provide drivers for Linux.
• More difficult to operate than Windows.

• Is more stable because it uses UNIX.
• Multitasking.
• Windows could recognize the file format.
• A more glossy look so good for graphic design / multimedia.
• Documents created in Mac OS can be read in another, and vice versa. Neither the format 'generic' (eg pdf, html, mp3, text) as well as a special format (for example. Doc,. Xls,. Ppt). Provided that no application program (application) on both platforms (Mac and Windows) that can read that format.
• Rarely exposed to viruses and worms.
• Open source code so that the Mac OS is difficult hijacked.
• There is a 'Time Machine' that will work automatically in the background without interrupting the running application to backup system and the ongoing changes in the data
• There is a program "Sherlock" are not just looking for the file on the disk and in the local network, but can also act on the Internet and search by keyword.

• Expensive, because the mac is a high technical specification. Accessories and spare parts lot but expensive.
• Only suitable for graphic designers.
• Less suitable for server applications and games. Not good to be a server and not a lot of great games like the games that made windows for mac.
• Mac can not be assembled because Apple has not given license to other companies to make hardware that can use the Mac OS.
• Mac OS can not be used together other operating systems that do not use the Mac OS system.
•  Technically, MacOS behind with other operating systems. Because only the MacOS are developing.
• Software in the Mac OS is not so complete.

• Linux operating system can interact with others in a way: file system compatibility, network compatibility, and emulation (simulation) operating system.
• Virtual memory makes linux has the ability to run the program - a program that is more than it should because of the use of swap memory.
• Scalability means that linux can run on your computer up to 286 XT machines for multi-processor Beowulf clusters with 16 pieces.
• Stability, Linux is extraordinary stable, if configured correctly, will live linux system continuously until the hardware is inadequate (broken), the other with windows that require a reboot periodically to maintain stability. One of these is the underlying stability of the version numbering shared libraries, most applications windows install new versions of a dynamic link libraries (DLLs), which resulted in other applications that overwrite other versions of the DLL is not working properly. Linux also inherited the tradition by supporting the UNIX file permissions (file permissions), which can prevent the alteration or deletion of files without permission of the owner, therefore, the virus basically unknown in the linux world.
• Supported by thousands of programmers around the world, so if you find a bug quickly to get a solution, even in a matter of hours if you found a bug, a workaround is available for download.
• Linux package is an integral means, depending on the time of installation the user desires.
• Already widely supported by hardware and software vendors the world although it is still inferior to the windows.

• Operating system is somewhat difficult to learn, especially for those who do not have strong computer basis.
• Applications are available yet as many windows.
• The operating system is not fully GUI (Graphical User Interface) even though it uses X-windows such as GNOME and KDE.
• The names of program packages between the distributions is different to other distros. Like
• Yaz.tar.gz.rpm.krpm.deb package and others.

• As the network software.
• Speed ​​communication between PCs in a LAN (Local Area Network).
• Easy network management
• Of the device (disk space, memory) are used only on the computer as a server.

• DOS-based mode of operation is so graphic.

That's all that I can say about the operating system may be bermanfa'at to you all ......
