Since China's access to the Internet, Internet information technology has developed rapidly, and major breakthroughs have been achieved in network technology, mobile chips, smart terminals, cloud computing, big data, satellite navigation and other fields, and a number of significant achievements have been achieved. The technology's independent innovation capability has been significantly enhanced, the intelligent terminal manufacturing industry has accelerated its catch-up, and has continuously cultivated new technologies and new applications to form new formats. However, it should be seen that compared with the world's advanced level, we still have a certain gap. The current situation in the world is strange. China must master core technologies to avoid being controlled by others in the new era and master the initiative of China's Internet development. The text is intended to explain:. ["Core technological breakthroughs are a manifestation of a country's scientific and technological strength.", "There is still a gap between us and the world's advanced level.", 'The initiative of Internet development should be in our own hands.', 'In the new era, it is even more necessary to break the "lifeline" of the core Internet technology.']
