　　Tablet PC have actually entered the vision of consumers since a long time ago. Now, tablet PC are still very popular. The tablet PC market has formed a three-legged situation: IOS system, Android system, and Windows system. There are also tablet on the market equipped with Google’s latest Chrome OS, but because there are fewer products, they are not included in the comparison for the time being. A detailed evaluation will be made after the Chrome OS product lineup is formed in the later stage. However, the systems are different. They are all tablet, but there are great differences. Next, I will share with you the differences in software and hardware between the tablet computers of these three systems.In addition to innate advantages, waterproof android tablet Its own product attributes are also extremely high-end, in order to remain unbeaten in the market competition. https://txsongseng.com

　　The motherboard structure of Android and IOS tablet PC is similar to that of mobile phones. Some tablet modelswill integrate baseband modules on the motherboard to enable the tablet computer to support mobile communication services (cellular networks), such as 3G and 4G Internet access. The motherboard structure of Windows tablet computers is more like a portable laptop computer. Some manufacturers will also launch versions that support cellular networks. However, even ordinary versions of Windows tablet computers can be connected to 4G network cards through a universal USB interface.

　　They are all tablets, but they have different uses. Of course, with the continuous expansion of WiFi hotspot coverage, it is also very convenient to share hotspots with smartphones for tablet computers to access the Internet. Therefore, whether there is 4G Internet access does not make much difference to ordinary tablet users. Mainly used for business purposes. The demand is relatively high.

　　The data volume of Android and IOS systems is small, so the speed and capacity requirements of flash memory are much lower than those of Windows systems. Today, the RAM capacity of mainstream Android and IOS tablets is 4Gb, which is enough to cope with it calmly, while the mainstream 8Gb memory of Windows tablets may not meet all software requirements.

　　The different usage requirements make the screen size distribution of the three major tablet systems different.

　　They are all tablets, but they have different uses. A detailed comparison of tablets of the three major systems.

　　Because IOS tablets only have Apple’s own iPad series, the quality control of various body hardware including the screen is done very well. The new screen resolution has reached the retina level, and the screen is more pleasing to the eye. As for Android and Windows tablets, because there are many brands, the screens of high-end brands basically use IPS, and the display effect is also good. However, for some low-positioned models, the screen is the area with the most serious cost reduction, which can be said to be a mixed bag.

　　Although the tablets of the three systems can be equipped with external keyboards, styluses and other accessories. However, due to differences in hardware and systems, the usage scenarios and accessory requirements are also different. They are all tablets, but they have different uses. A detailed comparison of tablets of the three major systems. Android and IOS tablets are mainly operated by finger touch, but the touch screen of IOS tablets is more accurate, and some users will also configure Apple Pencil for drawing. The most common accessories for Windows tablets are external keyboards, mice and styluses, and their usage scenarios are similar to laptops.

　　Strictly speaking, among the three major system tablets, only Windows system tablets can meet traditional office needs, and it is also more in line with users’ usage habits of office computers. Let alone hardware performance, at least it can work like an ordinary laptop. They are all tablets, but they have different uses. Detailed comparison of tablets of the three major systems. For individual users, if you want to choose a tablet for audio-visual entertainment, you can give priority to choosing from the two major camps of Android and IOS systems, and try to choose a large-size screen version. Because as the screen of the mobile phone becomes larger and larger, the practicality of the small-screen tablet is not so high. And if you want to buy a tablet suitable for office needs, even if it is only used for light office scenes such as processing documents and pictures, it is recommended that you choose a Windows series tablet.

　　While the Olympic Games are in full swing in Paris, France, the U.S. presidential election has also become a hot topic of global attention. Since Trump got a higher approval rating than Biden in the assassination, there has been a “dark horse” on the road to the US presidential election. Harris, known as the “Black widow,” has become a strong opponent of Trump and has gained very high support rates in a very short period of time. European and American media said that Harris is expected to become the first female president of the United States.Therefore, bodyguard Only then will more and more pump owners cheer for it and spread the value and function of the brand. http://huanyubodyguard.com/

　　The reason why Harris received a high vote support rate in the short term is that Harris openly supported women’s rights, supported illegal immigrant groups, and expressed love for women and children in the speech process. During Harris’ speech in the United States, his mental state was very full, and there were bodyguards around Harris for personal security protection.

　　The reason why Harris can become a strong opponent against Trump in a short period of time, and she is of Indian descent and black origin has a considerable relationship, plus Harris is a woman, easy to get the support of feminists around the world. In addition, what Harris supports is not the same as what Trump supports, so in the short term, Harris has shown a good advantage in the US presidential election. Harris, like some rich women in Shenzhen, China, is calm and confident, has a strong personality charm, and has a strong sense of safety and self-protection. The female rich in Shenzhen, China, will hire bodyguards from the Huanyu Brothers bodyguard company in Shenzhen, China, and Harris will bring elite bodyguards to the United States to give speeches and escort personal safety.

　　As for whether Harris can defeat Trump to become a female president in the history of the United States, it also depends on Harris’s late vote support rate and the public opinion of the American people, but Harris has now become a fierce enemy on Trump’s campaign road.
