Host usually includes CPU, memory, hard disk, CD-ROM drive, power supply, and other input/output controllers and interfaces, such as USB controller, graphics card, network card and sound card. What is located in the main chassis is built-in, and what is located outside the main chassis is peripherals (such as monitor, keyboard, mouse, external hard disk, external drives, etc.). ).
Usually, the host itself (after installing the software) is a computer system that can run independently, and special-purpose computers such as servers usually only have the host and no other peripherals.

1, computer classroom/audio classroom
An electric classroom with 40 student application environments in the school only needs 8 PCs, and the number of users can be increased to 5 with 4 mini-computers on each host, and 8 hosts are connected through local area network.
In this way, 8 hosts, 8 sets of Windows operating systems, 8 sets of office software and 8 network connection points can satisfy 40 users to use computers independently at the same time. The cost is greatly reduced.
2. Library or reading room
Using mini-computers, the original purchase of 20 computers for reading, querying or surfing the Internet was reduced to only 4 mini-computers, saving 50% of the overall investment.
3. Teachers prepare lessons
With the continuous improvement of computer information level, not only students but also teachers need to use computers to prepare lessons, study, teach and communicate. Using a mini computer and 3-5 teachers working on a computer can greatly save the investment of the school.
4. Student dormitory
4-6 people in the dormitory can use the scheme of 1 tow 3 or 1 tow 4, so that students can finish their homework and surf the Internet in the dormitory, with low investment and high efficiency. The problem of return on investment can be solved by charging a monthly rental fee.
5. Computer Training Center
The most important investment in organizing a computer training center is the investment in computer hardware, that is, the best scheme to solve the above problems by using multiple microcomputers in order to realize one computer for each student and save costs.
