What are two advantages of using computer virtualization? (Select two items. )
Second, effective use of hardware resources: With the continuous improvement of PC hardware performance, ordinary office workers only do daily business, resulting in a serious waste of computer CPU resources and insufficient utilization rate 15%. Desktop virtualization can concentrate on using the idle CPU, memory and other resources of desktop PC and distribute them to other users.
Third, easy maintenance and management: employees are usually not proficient in computer technology, which increases the complexity of PC terminal management by managers. Desktop virtualization concentrates employees' desktops on * * *, enjoying the unified maintenance of PCs or servers, without managing each PC one by one.
Fourth, high security: PC terminals have local storage, employees can install all kinds of software at will, which is vulnerable to network or other potential viruses, and the system security is poor. Desktop virtualization concentrates all software on the server, including antivirus software, unified installation, upgrade and maintenance. Secondly, the USB interface of the terminal can be set with closed or open rights management, which greatly improves the security.
5. Quiet and non-radiation power consumption is small: the power consumption of traditional PC is about 200W, which is large, and the noise interference of chassis fan is also serious. In addition, the body radiation is strong, which is not good for employees. However, the zero terminal power consumption used in desktop virtualization is generally only 5W, and the fan-free design of solid-state office equipment is silent and radiation-free, such as NComputing L300 zero terminal.
