Advantages:
Multi-user use
A computer mainframe can be used by more than 30 users at the same time. Each user only needs to prepare a keyboard, a mouse, a monitor and a zero terminal. No one needs a host except the host administrator.
The volume is reduced and the cost is reduced
Because all data operations, management programs and operating systems in the traditional PC host are "transferred" to the remote server based on the concept of cloud computing, the computer terminal on the desk can be greatly "slimmed down", and the power consumption is less than 3.5 watts, which is 5% of the common desktop computer.
Without CPU, memory and system, it also means a long waiting time for computer users, electromagnetic radiation and computer viruses to be solved one by one.
Disadvantages:
Completely dependent on the network
The quality of user experience is completely determined by the network. If there is no Internet, there is no way to use it, and the corresponding China Internet speed is the bottleneck.
Safe and unreliable.
It depends entirely on the optimization of the server by the service provider's technicians. Once the server is hung up, if it is returned or even disconnected, it is best to have local security.
