Question: Happiness is contagious , as researchers reported on Thursday.

People with the most social connections -- spouses, friends, neighbors and relatives -- were also the happiest, the data showed. "Each additional happy person makes you happier," Christakis said.

"Imagine that I am connected to you and you are connected to others and others are connected to still others. It is this fabric of humanity, like an American patch quilt."

Each person sits on a different colored patch. "Imagine that these patches are happy and unhappy patches. Your happiness depends on what is going on in the patch around you," Christakis said.

"It is not just happy people connecting with happy people, which they do. Above and beyond, there is this contagious process going on."

And happiness is more contagious than unhappiness, they discovered.

"If a social contact is happy, it increases the likelihood that you are happy by 15 percent, " Fowler said. "A friend of a friend, or the friend of a spouse or a sibling , if they are happy, increases your chances by 10 percent," he added.

A happy third degree friend -- the friend of a friend of a friend -- increases a person's chances of being happy by 6 percent.

"But every extra unhappy friend increases the likelihood that you'll be unhappy by 7 percent," Fowler said.

The finding is interesting and it is useful, too, Fowler said.

"Among other benefits, happiness has been shown to have an important effect on reduced mortality , pain reduction, and improved cardiac function. So better understanding of how happiness spreads can help us learn how to develop a healthier society," he said.

The study also fits in with other data suggested in 1984 that having $ 5,000 extra increased a person's chances of becoming happier by about 2 percent.

"A happy friend is worth about $ 20,000," Christakis said. 1. what is the worth of a happy person?

Question: A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network (WAN) not only covers a larger geographic distance, but also generally involves leased telecommunication circuits or Internet links. An even greater contrast is the Internet, which is a system of globally connected business and personal computers.

Ethernet and Wi-Fi are the two most common technologies in use for local area networks. Historical technologies include ARCNET, Token ring, and AppleTalk.

The increasing demand and use of computers in universities and research labs in the late 1960s generated the need to provide high-speed interconnections between computer systems. A 1970 report from the Lawrence Radiation Laboratory detailing the growth of their "Octopus" network gave a good indication of the situation.

A number of experimental and early commercial LAN technologies were developed in the 1970s. Cambridge Ring was developed at Cambridge University starting in 1974. Ethernet was developed at Xerox PARC in 19731975, and filed as . In 1976, after the system was deployed at PARC, Robert Metcalfe and David Boggs published a seminal paper, "Ethernet: Distributed Packet-Switching for Local Computer Networks". ARCNET was developed by Datapoint Corporation in 1976 and announced in 1977. It had the first commercial installation in December 1977 at Chase Manhattan Bank in New York. 1.

Question: Braille is a tactile writing system used by people who are blind or visually impaired. It is traditionally written with embossed paper. Braille users can read computer screens and other electronic supports thanks to refreshable braille displays. They can write braille with the original slate and stylus or type it on a braille writer, such as a portable braille notetaker or computer that prints with a braille embosser.

Braille is named after its creator, Louis Braille, a Frenchman who lost his sight as a result of a childhood accident. In 1824, at age 15, he developed a code for the French alphabet as an improvement on night writing. He published his system, which subsequently included musical notation, in 1829. The second revision, published in 1837, was the first binary form of writing developed in the modern era.

Braille characters are rectangular blocks called "cells" containing tiny bumps called "raised dots". The number and arrangement of these dots distinguish one character from another. Since the various braille alphabets originated as transcription codes for printed writing, the mappings (sets of character designations) vary from language to language. Furthermore, in English Braille there are three levels of encoding: Grade 1 a letter-by-letter transcription used for basic literacy; Grade 2 an addition of abbreviations and contractions; and Grade 3 various non-standardized personal shorthands. 1. Who came up with Braille?
2. Is it named for him?
3. When was he trying to make night writing better?
4. What did his code represent?
5. How old was he then?
6. What was published in 1937?

9. During what period?
10. Who is braille meant for Provide a numbered list of answers.
