When did the Internet come out in China? Ask God for help

3. In April, the education and scientific research demonstration network project in Zhongguancun area entered the Internet, and since then, China has been officially recognized as a country with the Internet.

4. The Internet was born in the late 1960s and became popular all over the world since the 1990s. In 1994, China officially took over the Internet. Function: The Internet has the function of quickly spreading information, which is called the "fourth medium".

The Chinese Academy of Sciences (Chinese Academy of Sciences for short) was established in November 1949. It is the highest academic institution of natural science in China, the highest consulting institution of science and technology, and the comprehensive research and development center of natural science and high technology.

2. Apply for an email address with the suffix of the mailbox system of the Chinese Academy of Sciences. The application process of each research institute of the Chinese Academy of Sciences may be different. Please consult the research institute for details.
