Practice shows that the UNIX is to host machine (mainframe) one of the few operating system reliability requirements, many UNIX host and server in the large and medium-sized enterprises abroad 24 hours a day, 365 days a year non-stop running, this is the NetWare, WindowsNT and OS2 can't be matched by the operating system, such as HP company recently announced the closure of the last host system, the enterprise all the information processing work is borne by the UNIX machines,,
Strong scalability
Extremely strong scalability UNIX system is the world's only can laptop, PC, and runs until the giant computer operating system, has recently announced the UNIX system for NC, no other operating systems can do this, in addition, because of the SMP, MPP, and Cluster technology, makes the commercialization of UNIX systems support CPU number reached 32, this makes the use a UNIX platform to expand capacity has improved further,
Good openness
Such is the nature of the UNIX system is the most important features, they are also of UNIX strong vitality, the concept of open system has been accepted generally by the computer industry, and become the main trend of development, all computer manufacturers claim that their products are open systems, and the concept of open is in constant development and improvement, it is a cover a wide spectrum, almost all of the system can find their own position, but there are obvious differences on procedure and we think that the most essential characteristics of open system should be used in the technical specifications can be open and free to use, and it is not monopolized and controlled by a specific vendor, UNIX is the most can fully embodies the essential characteristics of open system, it is this openness to more completely, making the development of the UNIX is full of power and vitality,
Strong network function
This is another important feature of the UNIX system, especially as the Internet technology based on UNIX TCP/IP protocol is developed, and become an integral component of a UNIX system, almost all UNIX systems include support for TCP/IP, therefore, in the Internet web server, UNIX server accounted for more than 80% and accounts for absolute advantage, in addition, UNIX support all of the most common network communication protocol, including the NES, DCE, IPX/SPX, SLIP, the PPP, etc., make a UNIX system can easily with the host, all sorts of wan and domain network connected,
Powerful database support
Because the UNIX system in various databases, especially in a relational database management system provides a strong support ability, therefore the main database, including Oracle, Informix, Sybase, Progress and so on all UNIX as optimizing the operation of the platform, and create a high cost performance,

Don't under Linux because very closely related to both!!
