1. It is said that the Qi surname is one of the surnames given to the descendants of the Yellow Emperor. It is the descendant of the second son of the emperor, Yao Yiqi (Tao Tang family). Emperor Yao was first granted the title of Tao Di, which is also called Tao Tang family. Its name is Yao, which is called Tang Yao in history. Later, the Qi family was granted the title of Liu state, which is now Tang County in Baoding. His descendants took the state name as their surname, and it was said that his surname was Liu. The history says that Liu's family is authentic. This is the surname of Qi Liu
2. From Ji surname,
is the descendant of King Tai of Zhou. It is said that after the death of King Wu of Zhou, King Cheng of Zhou succeeded to the throne and granted Wang Ji's son Liu Yi. His descendants took the city as their surname and passed down the surname Liu from generation to generation. In the Eastern Zhou Dynasty, Liu Kanggong, a member of the royal family, was re granted the title of King Liu. This is the Liu surname of Ji
3. He gave his surname to Liu. Liu Bang, Emperor Gaozu of the Han Dynasty, carried out the policy of making peace with relatives, and married his royal daughter to Shan Yu; According to the custom of the Xiongnu, the nobles all followed their mother's surname, and the descendants of Shan Yu all followed Liu's surname. So the surname Liu came into being
In the period of Wei, Jin and sixteen states, in order to win the support of the people in the Central Plains, a group of Xiongnu claimed to be the descendant of Han Dynasty Princess and Xiongnu Shanyu, and always used their mother's surname, so their surname was Liu. They successively established the Han, former Zhao and Xia regimes in Shanxi, Shaanxi and Inner Mongolia, and later settled in Henan. It is known as "Liu family of Henan" in history. Liu Yuan, the founder of the former Zhao Dynasty, was a Hun aristocrat In the Northern Wei Dynasty, one of the "eight surnames of xunzhen" had the Dugu family. After Emperor Xiaowen moved the capital from Datong to Luoyang in the 20th year of Taihe (494), he carried out the Sinicization reform in 496 and changed the Dugu family from Xianbei to Liu familyLi Xiong
& quot; Li & quot; The fruit of a small decious tree is called "plum", which is yellow or purplish red when ripe, and can be eaten: ～ Dai Taojiang (originally used as "peach" and "Li" sharing weal and woe to describe brothers' love and help each other, but later used as mutual substitution or acceptance on behalf of others). Peach Report To avoid unnecessary suspicion. If a person is loyal and honest, he will move others. 2. Surname. 3. The same "reason" in ancient times, which is the pronoun of ancient judges
1. Recing costs
Desktop Virtualization will rece costs for customers, which is the first reaction of many people to its benefits. In fact, desktop virtualization integrates a lot of resources. For the long-term development of enterprises, it really reces the cost. However, in terms of initial cost, whether desktop virtualization can rece the cost still needs specific analysis
if you want to transform the virtual desktop architecture on the basis of the existing one, you need to virtualize the background system first, and then deliver the virtual application or desktop to the existing PC terminal. Although only one image of the operating system is kept in the background, the license still depends on the number of desktops, which is no different from the physical desktop, But you have to pay extra for desktop virtualization related software and license fees. Therefore, in the early stage, desktop virtualization does not mean to rece costs, its cost advantage needs to be graally revealed
many people think that the initial investment of desktop virtualization will have obvious advantages in building a new IT architecture, because there is no need to buy more expensive PCs, just thin terminals. In fact, there are many ways to carry desktop virtualization, thin client is just one of them. For mobile office workers in the company, it is their hope that computers can carry virtual desktop or applications. This is mainly to remind users not to equate desktop virtualization with thin client and simplify terminal
2. It is convenient for enterprise it to centralize the control of Terminal Desktop
enterprise IT departments, especially large enterprises, have a headache in it equipment management, especially in enterprises with tens of thousands of employees. With the help of virtual desktop, it department receives all desktop management to the back-end data center, and can manage and maintain desktop image and related applications at home
therefore, virtual desktop provides an excellent management means for enterprise it, and the efficiency of centralized management is incomparable with physical desktop in the past. Moreover, it will also indirectly affect the operating costs of enterprises. For example, in the IT Department of an enterprise, you can think about whether it costs to go to a branch office to maintain the desktop in person
however, are many people worried that there will be no personal desktop after desktop virtualization. If you only use thin clients, there is no local desktop, but in fact, virtual desktop can coexist with local personal desktop, which reflects the advantages of full-function computers
3. Data is more secure
Desktop Virtualization needs application virtualization, and the implementation of the application is in the background data center, so the data generated by the application is in the data center, not on the storage device of the user terminal, so even if the terminal is damaged or lost, the application data of the enterprise will not be lost, This greatly improves the security of enterprise sensitive data
on the other hand, because enterprise it can centrally maintain desktop and applications in the background, the cost of virus prevention will be reced
4. Improve the efficiency of cooperation with partners
it is very common for large enterprises to cooperate with other business partners. Because the IT architecture and system of each company are not necessarily the same, it also brings many difficulties for this kind of collaborative office. Through desktop virtualization, enterprises can generate corresponding virtual machines for these businesses, deploy corresponding desktops and applications, but the data can be transparently centralized to the background. After the collaboration is over, they just need to shut down the corresponding virtual machines, and there is no need to purchase it terminals for them, which undoubtedly means that proctivity is improved
Tianyuan tengchuang technology, a professional virtualization solution provider, replied that I hope it can help you.
let's understand supercomputers.
what is supercomputer
supercomputer is usually composed of hundreds, thousands or even more processors, which can calculate large and complex tasks that ordinary PC and server can not complete. In order to help you better understand the computing speed of supercomputers, we compare the computing speed of ordinary computers to the walking speed of alts, so supercomputers can reach the speed of rockets. Under the premise of this speed, people can predict and explain the natural phenomena which could not be tested before by numerical simulation
