Traditionally, people think that the fastest way to publish scientific research results is serial publication, but this view should be changed at present. A large number of preprint servers have been established on the Internet, and many scientific research institutions, academic organizations, experts and scholars around the world first publish their scientific research results on the Internet, not only for the appreciation of the world peers, but also to show that they are the owners of the results, thus greatly shortening the time for scientific research results to meet the public.

Verb (short for verb) Problems in the Internet.
Although the Internet has such a huge resource pool and provides such meticulous services, we should be soberly aware that it also has many negative effects or problems.
1. Security issues
At that time, the designers of ARPAnet just wanted to build a network that can resist nuclear attacks (that is, a network that can still work normally after being partially damaged), without considering that it should be shared by all mankind. Therefore, the internet has always lacked security protection measures, leaving security issues to users to solve themselves. At present, developed countries have carried out so-called firewall research, forming a protective layer between internal information and external resources.
2. Information pollution problem
People's ideal Internet should be that everyone is equal, helping each other and enjoying information. However, the current situation is that there are a lot of false information (also known as "black" information) and "yellow" information because of the diversified ideology, fierce business competition and chaotic information transmission on the Internet.
The so-called "black" information is the false information that people deliberately publish, such as sending "deceptive emails" to users saying that they have won the grand prize, or being hired as a senior manager by a big company. At present, false information has reached the level of forging aircraft performance parameters and causing aircraft accidents.
The so-called "yellow" information is also pornographic information. Some people publish pornographic information on the internet under the guise of cultural freedom, and even have pornographic performances, also known as "computer prostitutes"; On the other hand, sending sexual harassment emails to users greatly interferes with the normal communication and work of users, especially female users.

1in the early morning of September 5, 995 1 1 until 2 pm, a big "browsing out" of the Internet made the performance of the whole American Internet drop to the extreme, and it took 40 minutes to successfully connect to the website. Experts believe that this accident is likely to be a precursor to more "slowdown", and the Internet must use more powerful routers or switches to support the rapid growth of users and traffic. Regional networks must also cooperate with each other as much as possible to make their networks run in a balanced way.
5. Cost problem
For a long time, the cost of using the Internet is very low. Due to the sharp increase of commercial users and non-American users, it is becoming more and more difficult for the American Science Foundation to bear all the expenses. Therefore, the American Science Foundation announced that starting from1September 4, 1995 14, the cost of tracking Internet users' addresses will no longer be entirely borne by the Foundation, but will also be borne by commercial networks, companies and non-profit organizations connected to the network.
