The times, requires the development of science and technology as well. Including the operating system on the computer. With all the shortcomings and advantages, computer users are trying to condition the computer to be as comfortable as possible and support the performance. Here is some information related to the three types of operating systems are widely used

1. UNIX
UNIX is an operating system that is used as the default operating system on different types of computers, especially the mini computer either as a workstation or server (system that provides a service on the network). Due to a unix server, move work from one computer to another kind of easy.
Unix operating system is designed as a portable, multi-tasking, multi-user, hierarchical file system and utilities.
Pros:
a. Sharing computer resources

• CPU and memory allocation,
• Data storage / disk,
• Printer / printer and program / utility

b. Increased reliability.
Computers in a network is more reliable than the stand-alone computer. If there is a computer that does not work, its role was replaced by another computer. The system can be set / controlled by computer users do not know that the commonly used being replaced by another computer. Disk storage systems can be set up security degrees. Such as CPU, disk system was replaced by a non-functioning system to another without being noticed by the user.
c. Savings.
Improved reliability and the use of resources with the operating cost savings. Price 10 10 MIPS computer is much cheaper than 1 100 MIPS computer. However, the ability of the tenth 10 MIPS computer can be almost equal to 100 MIPS computer skills if done high utilization. Other savings come from the use of the printer server and file server (1 system disk to a lot of data or computer).
The types of UNIX:
UNIX is an operating system developed by numerous parties. Each party yangmengembangkan UNIX, adding its proprietary technology into UNIX, which although it is outside the standard, able to make the UNIX operating system is stronger or more reliable. Type - the type of Unix, among others:

1. A / UX
2. Domain / X
3. Darwin
4. CTIX
5. Distrix
6. UNICOS

2. Windows
Windows is an operating system for servers operasinnya 32 bit system from Microsoft is an ancestor of the operating system Windows 2000, Windows XP, and Windows Server 2003 Operating Vista.Sistem is on awalnnya supports multiple platforms Mikroprosesor.Windows NT Server is not built on MS-Dos (not like Windows 95) Being able to observe 4 Gb.
Version:
Since its launch, Windows NT version has undergone several improvements, which are as follows.

1. Windows NT version 3.1.
2. Windows NT version 3:50.
3. Windows NT version 3.51.
4. Windows NT version 4.0.
5. Windows NT version 5.0 (or known as Windows 2000, version 5.0 build 2195 internal).
6. Windows NT version 5.1 (or known as Windows XP, version 5.1 build 2600 internal).
7. Windows NT version 5.2 (or known as Windows Server 2003, internal version 5.2 build 3790).
8. Windows NT version 6.0 (or known as Windows Vista).
9. Windows NT version 7.0 (code name "Vienna").
10. Windows NT version 8.0 (code name "Metro")
11. Windows NT version 6.1 (or known as Windows Server 2008, which has the codename Longhorn Server

Advantages:

1. Server Capacity to serve more Simultaneous Koneksinnya.
2. Fault tolerant disk driver which supports disk mirroring and disk stripping with parity (RAID 1 and RAID 5)
3. Free from Code 16 Bit MS-Dos belonging, support 32-bit operation and all features offered by 32-bit microprocessor as can be observed up to 4 GB of memory and Protected.
4. In design to be compatible with previous OS like MS-Dos, IBM OS / 2.

Disadvantages:

1. Changing the basic configuration can be done rarely succeed. This applies to the default value, log file format which is also the default option propritary and-index, all of which are standard should always be stored on drive C. Administrator in this case should not have to do the job, until the entire system is running as it should, before you can make changes.
2. From the above cases, it takes a very complex configuration changes to ISS Server, which can be said to be very difficult and inconvenient. From the administrator believes the Registry file change activity is relatively heavy work for systems using Windows NT as the operating system.

3. LINUX
Pros:

• Linux is relatively stable. Computers that run on top of the UNIX operating system are well known stable running nonstop. Linux, which is a variant of UNIX, also inherit this stability. Rarely encountered, the computer suddenly hangs and have to press Ctrl-Alt-Del or Restart to end the incident.
• Linux has backwards compatibility better (better backward-compatibilty). Hardware has been aged longer, it is still very useful and can run well on Linux. In addition, never met a more documents can not be read on the new Linux version is longer. On Windows, if we are required to keep abreast of the development of hardware, such as the case file. Docx (Word 2007-2010) which can not be opened with Microsoft Word 2003 or later below.
• Support diverse communities and spread around the world.
• Linux in addition to a free to use, it's free to be modified and redistributed. Even we can develop our own distro.

Disadvantages:

• The installation software / applications that are not as easy in Windows. Installing software on Linux, it will become easier when connected to the internet or if have a CD / DVD repository him. If not, then we have to download one by one package is needed along with its dependencies.
• For system administrators who are not familiar with Unix-like (such as Linux), then inevitably have to learn this. So the requirement is to be a human administrator who likes to learn new things and continually learning.
• Applications in Linux not as efficacious application in Windows.
• Directory structure and access rights are confusing for those who are familiar with Windows and are not familiar with UNIX / Linux at all.
