1. The name of which world famous search engine was created as a result of a spelling error?
When Larry Page and Sergey Brin came up with the name of the new search engine, they wanted to express in it the huge amount of information that the system is capable of processing. Their colleague suggested the word "googol". This is the name in mathematics for a number consisting of one followed by one hundred zeros. He immediately checked the domain name to see if it was available and, finding that it was available, they registered it. However, he made a mistake in spelling the word: instead of the correct 'googol.com' it turned out to be 'google.com'. I liked this word and became the name of the search engine.
2. The computer program for recording discs (“burning”) Nero Burning ROM received its name for a reason. Where did this name come from?
3. History of the Apple logo
Probably the most famous Apple logo is the multi-colored apple. Now this is what is considered the vintage retro sign of Apple, although officially the first one was not an apple. The very first Apple logo depicted Isaac Newton sitting under an apple tree - a simple plot of the legend about Sir Isaac's discovery of the force of universal gravity.
4. QWERTY is currently the most popular Latin keyboard layout used for English. Layouts for many other languages have been created on its basis. The name comes from the 6 left characters of the top row of the layout. The arrangement of letters on a computer keyboard is a legacy of typewriters, which appeared in the 19th century. Why are the letters on the keyboard arranged so strangely?
This keyboard layout was created for typewriters, which broke down due to too high typing speed. At high printing speeds, individual hammers did not have time to return to their place and were constantly interfering with each other. In this regard, Christopher Sholes, the inventor of typewriters, developed a keyboard in which letters frequently found in texts were placed further apart. So the keyboard design was originally aimed at slowing down the typist's work.
5. The best minds of the companies that invented CDs - Sony and Philips - wondered about the diameter of the disc, since the larger the diameter of the disk, the more information would fit on it. Sony Corporation Vice President Norio Oga insisted that the CD should be able to accommodate the most popular piece of music. What popular work are we talking about?
The question arose in 1979, when CDs were invented, but the partners did not have a common opinion on the technical parameters of the disc. Initially, Sony wanted to use disks with a diameter of 100 mm, and Philips stood for the 115 mm size, because This is the size of a standard audio cassette. The disk capacity in this case was estimated at 60 minutes. Legend has it that Sony Corporation Vice President Norio Oga insisted that the CD must be able to accommodate Beethoven's 9th Symphony (sort of the most popular piece of music in Japan in 1979, according to a survey) because... then it will be possible to record up to 95% of classical works on CD. The longest performance of the symphony (under the direction of Wilhelm Furtwängler) was taken as a guide – 74 minutes.
6. Who is Bluetooth technology named after?
Bluetooth technology was named after the formidable Danish king Harald I Bluetooth. IN X century, this king united the disparate Danish tribes, and Bluetooth was intended to do the same with communication protocols, uniting them into one universal standard.
7. First appearance of the word “Spam”
The word "SPAM" originally appeared in 1936. It stood for SPiced hAM (spicy ham) and was a trademark for Hormel Foods Corporation's canned meat, a spicy ground pork sausage.
8. You, of course, know the motto of the sports movement “Faster! Higher! Stronger!". What, in your opinion, should be the motto that characterizes the development trends of laptop-type computers?
"Faster! (higher operating speed) More! (increasing memory capacity) Thinner! (reduction in size).”

A programmer is a specialist who writes and edits programs for computers (any computing device), that is, programming. A traveling salesman (French commis voyageur) is a traveling sales intermediary who, moving around the market, plays the role of a simple intermediary or acts on behalf of his client (seller); a traveling sales agent of a company who offers customers products based on samples and catalogs. William Henry Gates III (born October 28, 1955, Seattle), better known as Bill Gates - American entrepreneur and public figure, philanthropist, co-founder (with Paul Allen) and largest shareholder Microsoft company. Until June 2008, he was the head of the company, after leaving the post he remained as its non-executive chairman of the board of directors. He is also co-chairman of the Bill and Melinda Gates Foundation. Webcam (also webcam) is a small-sized digital video or photo camera capable of capture real-time images intended for further transmission over the Internet (in programs such as Skype, Instant Messenger or any other video application).
Let's look at some interesting facts from the history of computer science. What do we know about this science? Only that modern society simply cannot do without it? The fact that the existence of computer games, the Internet, online communication, calls to the other end of the hemisphere would be impossible without the advent of computer science.
- For the first time, computer science was named in 1957 as a technical field that carried out automated information processing using a computer.
- It was on December 4, 1948 (Informatics Day) that the “electronic computer” created by Rameev was registered.
- September 13 (programmer's day) is the 256th day of the calendar. This number is the maximum power of two and can be expressed in terms of an eight-bit byte. But in a leap year, the celebration falls on September 12th.
- The M-1 computer was created in 6 months, and became the first machine in which all logical circuits were created on semiconductors. 256 words – that’s how much memory she had. 15-20 operations with 23-bit numbers per second.
- M-1 is not the first computer; before it, a small electronic calculating machine was created by the team of Sergei Lebedev. It occupied several tens of square meters and was able to carry out about three thousand operations per second. There were huge queues for this computer, because everyone wanted to make their calculations easier.
- The microprocessor weighs only 2 grams, but its production requires 1.6 kg of fossil fuels, 72 grams. chemicals, 32 liters of water.
- In the 70s, physicist James Russell invented the compact disc only because he didn't like the sound of Mozart when the needle scratched the record. Subsequently, his invention was patented by Philips, appropriating the rights to itself.
- In English, “bug” is a bug, a computer error, but it got its name thanks to a team of research institute employees. An ordinary situation: the computer broke down, they spent several weeks looking for the cause. In the end, it turned out that the moth closed the contacts with its wings, and since then the “bug” has had this name.
- 36 thousand transactions - this is the calculation of the specialized computer base of the New York Bank, which carries out transactions with securities. 1985, the height of trading, and then the program’s memory ended. Due to a failure in the system, the bank found itself in huge debt, approximately $32 billion in debt. To eliminate the error, the bank had to borrow $24 billion, while leaving all its existing assets as collateral.
- The winner of the great grandmaster Garry Kasparov is a computer. In 1994, it was a computer game that was able to beat the great chess player.
- The World Wide Web was created in the 60s of the last century by American developers for the defense forces of the state.
- Facebook is the most popular social network in the world, the monthly turnover of photos is 3 billion. If FB were a country, it would round out the top three in terms of population.
- The word "spam" where it came from? Back in 1936, an American organization released new canned food called SPiced hAM. Due to the Second World War, sales were stopped, but after it it was necessary to sell expired goods. A large-scale advertising campaign was carried out, which became the standard of importunity. And 50 years later, a certain Dave Rhodes sent a bunch of identical SMS messages, advertising a new financial pyramid. Since then, “spam” has been an annoying mailing.
- The most destructive virus in the history of computer science - “I Love You” or LoveLetter. The letter was sent to unsuspecting people; upon opening it, it infected all computer data, creating its own copy to be forwarded to all contacts. It caused $15 billion in damage, affecting over 3 million computers.
- The very first and largest virus attack was called the "Morris worm". Not only were about 6 thousand computer systems infected, but also the NASA research center itself, causing damage of $96 million.
The computer has become so familiar in our lives that we perceive it as a workhorse and little think about how many interesting things are connected with our PC. We decided to fix this. So, interesting facts about computers:
1) A modern personal computer has ten times more power than it once took to launch and land a man on the moon.
2) The CD capacity is enough for 72 minutes of music. This is exactly the duration of Beethoven's ninth symphony, which the creators of the new product were guided by.
3) A split second is enough for us to evaluate the quality of the site we have visited.
4) Chinese gamers are prohibited from playing games that promote murder, such as GTA or Postal. Hackers are not welcome in the Celestial Empire either: they face serious prison sentences, and in 1998 a couple of hackers were even sentenced to capital punishment.
5) Hackers, of course, are not worth protecting - criminals of the information space. But also don’t forget about your loved ones. Some accounts, email addresses and other personal pages on the Internet are just asking to be broken! The most popular passwords are numbers in ascending or descending order, as well as date, month and year of birth. Many users are so careless that they even enter the same set of characters in the “login” and “password” windows.
6) If you often sit at a computer for a long time, then you blink at least seven times a minute. This is how our eyes try to prevent “office vision” syndrome.
7) Bill Gates' official email receives millions of emails every day. Need I say that the vast majority of them remain unanswered?
8) There is a lot of debate about whether a computer can catch up and surpass us in abilities. But he was already recognized as “person of the year”: in 1982, this was done by the employees of Time magazine.
9) People who are afraid of computers and everything connected with them are called cyberphobes.
10) 2/3 of Americans surf the Internet at least three hours a day. We think our compatriots are not much less...
Computer related services are considered a very profitable business. At least three out of six rich people made their fortunes in the IT sector.
11) The sysadmin holiday is celebrated in many countries. But only in the States is it called “System Administrator Appreciation Day.”
12) Contrary to popular belief, computers most often break down not from problems in the electrical network or from malicious viruses. They should “say thank you” to their owners who spill tea, coffee, soda and other drinks on the keyboard.
13) if we take all email messages transmitted in the world as 100%, then 94% of them are spam.
14) The first e-mail was sent in 1971 by Ray Tomlinson, the author of a program for exchanging messages between computers. He also suggested using the @ icon to separate the username and computer name.
15) The creators of the Google search engine wanted to name their brainchild Googol (10 to the hundredth power - that’s how many pages they were going to index), but the domain with that name was already taken.
16) The first dot matrix printer was developed in 1964. It was used in Seiko brand watches to permanently print the exact time.
17) The Internet and computer games are considered the most devastating threat to employee productivity. The amount of time workers in the average American office spend on the Internet is still unknown, but they spend about half a billion hours a year playing computer games.
18) The famous combination - the three-finger program - Ctrl-Alt-Del - was created and implemented by one of the IBM PC developers, David Bradley.
19) The first personal computers had a very limited amount of memory - only about 16 kilobytes.
20) A computer scientist is still not a woman’s profession. The world's largest IT corporation, Microsoft, employs 75% men and only 25% women.
