Unfamiliar technological knowledge

1. Regular web addresses start with "WWW". What does it mean?

Actually, "www" is short for "world wide web" (global information network), and for short it can also be called "web". The Chinese name is "World Wide Web".

The World Wide Web is an information space used to store information (such as web pages and documents) on Internet, a network. The world's first programmer was a woman, and that was Ada Lovelace from England, a legendary aristocrat of 19th century. CERN officially launched world's first website on 6 August 1991. The website explains what World Wide Web is and how to use a web browser.

2. Hackers can easily access your home network via WIFI

If a hacker connects to your home WIFI, he can easily break into your home computer network and get all your account passwords and personal privacy. Relatively speaking, if you connect to a WIFI trap set by hackers, your personal information will also be visible at a glance.

Therefore, please do not accidentally connect to unfamiliar unencrypted WIFI in public places. If you need to connect, please try not to perform property security transactions such as online banking or online shopping under such circumstances. If you find an unfamiliar free WIFI, please do not connect at will until you confirm security.

3. Why are English letters on keyboard not in order, but randomly?

In fact, in early days, keyboards were arranged in English letter order. However, when a typewriter is typing, adjacent keys collide with each other and cause jamming, so out-of-order letters can slow down typing speed. speed, less sticky keys. Later, after practical development, letter distribution of current "QWERTYUIOP" was formed.

4. What is super-artificial intelligence?

The concept of artificial intelligence is relatively broad, so there are many types of artificial intelligence. According to level of artificial intelligence strength, they are divided into three categories: "weak artificial intelligence", "strong artificial intelligence" and "super artificial intelligence".

"Weak AI" is an AI that is good in one way, such as World Go champion capable of defeating humans, AlphaGo AI, and its Chinese name is "Alpha Go".

A "strong artificial intelligence" refers to an artificial intelligence that can compete with humans in every aspect and can do mental work that humans can do;

"Super AI" is much smarter than humans in all areas, super AI can be a crushing existence of human intelligence.

A survey of hundreds of scientists was conducted, they believe that the emergence of strong artificial intelligence will be in 2040, and it will be produced no later than 2075. But do people really look forward to this day?

5. Is it possible to copy and transmit thoughts of human brain?

Is sum of information in human brain so-called soul? Scientists are working hard to extract human soul. In future, it will be possible to digitize all information in human brain using nanotechnology, and a digitized computer can be copied and transferred to a computer (robot). Will line between humans and artificial intelligence become more blurred by then?

Scientists once implanted an electronic component into brain of a sea shark, which successfully affected its behavior, and other scientists continue to experiment with mice and monkeys and continue to explore potential of implantable chips.

In future, people will be able to gain knowledge by implanting chips in their brains. But do people really look forward to this day?
