First of all, we must clarify their concepts.
1, workstation, is relative to the server.
2. Thin client is a small commercial PC designed based on PC industry standard, which uses professional embedded processor, small local flash memory and simplified operating system.
Configure a professional embedded processor with low power consumption and high computing function. Non-removable local flash memory for storing the operating system, and standard input/output options for local system memory, network adapters, graphics cards and other peripherals. Thin client has no detachable parts, which can provide a safer and more reliable use environment than ordinary PC, with lower power consumption and higher security.
The thin client adopts Linux.

3. What is a quasi-system?
According to the specifications of the current quasi-system products, it can generally be said to be a chassis with a motherboard, which integrates the basic display, audio system and common interfaces. To form a computer, other accessories need to be purchased and assembled by users. For example, you need to buy CPU, memory, hard disk, monitor, speaker, CD-ROM and so on. At present, the quasi-system on the market has both PC models and server models. Obviously, the general quasi-system has an angelic appearance.
There is only one reason for the birth of quasi-system, which is to reduce the cost risk for computer manufacturers. Quasi-system was originally developed from semi-finished PC system. At that time, in order to avoid the price fluctuation of parts during transportation, manufacturers provided a more flexible customization model. Quasi-system product is to assemble some computer parts that are not sensitive to price and then sell them to customers. The advantage of this is to reduce the risk of price fluctuation of accessories and minimize the damage of sensitive parts in transportation. This undoubtedly facilitates the production and sales of manufacturers.
4. minicomputer refers to a kind of high-performance computer, whose working principle is similar to PC and server, but its performance and use are completely different from them. It is a high-performance computing product first developed by DEC (Digital Equipment Company) in 1970s.
Minicomputers have a unique architecture that distinguishes PCs from their servers, as well as proprietary technologies of various manufacturers, and some also use minicomputer-specific processors. For example, the minicomputers of Sun Company of the United States and Fujitsu Company of Japan are based on SPARC processor architecture, while the minicomputers of Hewlett-Packard Company of the United States are based on PA-RISC architecture.
Compaq is an Alpha architecture. In addition, I/O buses are different, Fujitsu is PCI, Sun is, and so on. This means that plug-in cards on small computers of various companies, such as network cards, graphics cards and SCSI cards, may also be dedicated. In addition, minicomputers generally use Unix-based operating systems, such as Sun and Fujitsu.
Solaris, HP uses HP-UNIX and IBM uses AIX. Therefore, minicomputer is a closed special computer system. Users who use minicomputers generally value the security and reliability of Unix operating system and the high-speed computing ability of dedicated servers.
