How well do you know the Internet?

What is INTERNET?

Internet is global network, working according to "single rules" and uniting millions of computers and thousands of computer networks around the world.

What is a protocol?

A protocol is a set of pre-agreed rules for transferring data between two devices. The main parameters described by the protocol include the type of error checking used, the method of compressing (compressing) information (if any), the method for determining the end of transmission by the transmitting device, the method for determining by the receiving device the fact of receiving a message.

Slide 9

What is IP?

IP is an acronym for Internet Protocol. One of the main protocols used on the Internet. The operation of the IP protocol can be compared to the operation of ordinary mail. The purpose of the IP protocol is to deliver packets to their destination, and it is not at all necessary that all packets go to the destination in the same way. The IP protocol defines the packet format and addressing scheme.

What is an IP address?

An IP address is when sending information via TCP / IP protocols, each computer connected to the Network must have its own unique address (otherwise, how will the IP protocol understand which machine to which packets should be transferred to). It's called an IP address. Currently, numeric IP addresses consist of four integers (from 0 to 255) separated by dots, such as 193.243.158.4.

Slide 10

What is a domain name?

A domain name is a name that identifies one or more IP addresses. For example, the domain name www.vn.ua corresponds to the IP address 193.243.158.4. Domain names are constituent parts URLs pointing to specific web pages. Every domain name has a suffix identifying the domain top level The to which this name belongs. This suffix comes last (.com, .net, .edu, .org, etc.).

What is HTTP?

HyperText Transfer Protocol (HTTP) is an application layer protocol used in distributed information systems hypermedia. It defines how messages are formatted and passed, and what actions Web servers and browsers should "take" in response to certain commands.

Internet 2011 in numbers: 2 billion users online

More than two billion people on the planet use the World Wide Web. It is noteworthy that almost half of active Internet users live in Asian countries.

Nearly 1 billion Internet users (922.2 million) live in Asia, according to a global analysis by The Royal Pingdom. At the same time, it is interesting that the penetration of the Internet among the population of Asian countries is only 23.8%.

dependent on world wide web residents of European countries. 476.213 million Europeans know what the Internet is (58% of the total population of European countries). The most Internet addicted users live in North America. 272.066 million use the Internet, with a network penetration of 78%. Slightly behind their "northern counterparts" are residents of Latin America and the Caribbean - 215.939 million network users. Internet penetration for this part of the world is 36.2%.

The fewest Internet users are in Australia and Oceania - only 21 million. Interestingly, even 11 years ago, the most “lagging” region was the countries of the Middle East (only 3 million Internet users), and now in this region 68.553 million citizens know and actively use the international network

Better a Corvette on a table than a Pentium in a dream.

Proverbs that are paraphrased in a computer way

Each new program- this is a well-forgotten old one.

Everything new is well forgotten old.

They are greeted by computers, escorted by programs.

By clothes they meet by mind they see off

A gift computer is not looked into the system unit.

They do not look at a given horse's teeth

A bird in the hand is worth two in the bush

Not all that WINDOWS that hangs.

Not all that glitters is gold.

What is removed from the basket is gone.

What fell from the cart is gone.

Charles Babbage 1792 - 1871 At school he showed great interest in mathematics. At 22, he received a bachelor's degree, and three years later a master's degree. For more than 10 years he was in charge of the Department of Physics and Mathematics at the University of Cambridge, Babbage was an amazingly versatile researcher, he was interested in everything. He also dealt with the calculations of the mortality of the population, the reform postal service, descended to the bottom of the lake, exploring the hot springs, climbed Vesuvius, participated in archaeological excavations, descended into the mines. And, of course, he did a lot of mathematics, geometry, number theory, and probability theory. Babbage was one of the first researchers of railway transport and traffic safety issues. The main components of the contribution to "computational science": the creation of a difference engine; creation of an analytical engine. Charles Babbage made history computer technology as the creator of the first programmable computer.

Augusta Ada Byron (Countess of Lovelace) 1815 - 1852 daughter of the poet George Byron). She was unlike anyone and possessed a talent that was not poetic, metaphysical. Along with a completely masculine ability to understand, manifested in the ability to decisively and quickly grasp the essence of the whole matter, Lady Lovelace possessed all the charms of a refined female character. Her manners, her tastes, her education, especially her musical education, in which she reached perfection, were feminine in the most beautiful sense of the word, and a superficial observer would never guess how much inner strength and knowledge is hidden under her feminine grace. Ada Lovelace was a student and assistant of Charles Babbage. The main components of the contribution to "computational science": - introduction of the concepts of cycle and work cell; - the idea of ​​program control of the calculation process; - invention of a system for speeding up calculations; - use of punched cards for input and output of information. Countess Lovelace entered the history of computer technology as the first programmer, the Ada programming language is named after her.

John von Neumann 1903 - 1957 (born in Budapest) He began to stand out with his extraordinary abilities very early: at the age of 6 he spoke ancient Greek, and at the age of eight he mastered the basics of higher mathematics. John von Neumann made a significant contribution to the creation and development of a number of areas of mathematics and physics, and had a significant impact on the development of computer technology. He noted that the machine must work with binary code, be electronic, not mechanical, and perform operations sequentially, one after another. He developed the basic principles of building computers, and for 50 years all computers were built on the basis of Neumann's principles.

Steve Jobs(1955 - 2011) entered the history of the late 20th and early 21st centuries as a pioneer and innovator, a man who saw five steps ahead. He single-handedly was able to budge not only the computer industry, giving birth to the Apple II and the Macintosh, but also the music industry, creating the iPod, the telephone industry, thanks to the iPhone, and the animation industry, along with the bold experiments of the Pixar studio. Now it’s even hard to imagine that at the origins of the world computer “monster” Apple was an ordinary guy, a hippie, from a small American town, without higher education, but with cosmic ambitions and a real talent for seeing what people like.

Description of the slide:

Steve Jobs, the founder of Apple, had a few things that made him calling card. We are talking about his black turtleneck, with a high neck, blue jeans and white sneakers. However, there was one more thing that never changed. The silver Mercedes-Benz SL 55 AMG, which he loved to drive, was his favorite and unchanged car. Jobs' car never had a license plate, leading some "experts" to claim that the Apple founder was flippant about paying fines. Another rumor claimed that Jobs had some kind of agreement with the authorities that allowed him not to install license plates. John Callas, the man who handled security issues at Apple, denied these claims. Interesting Facts from life In fact, everything turned out to be much simpler. Steve (or someone close to him) discovered a gap in California law. According to the law, license plates must be installed no later than six months after the purchase of a new car. Jobs entered into an agreement with a car dealership, according to which he received a new silver Mercedes-Benz SL 55 AMG every six months, and returned the old one, exactly the same, back. Thus, it was convenient for both Jobs and the car dealership, as he put up for sale a car that had been run in by Steve Jobs himself.

How is informatics related to our everyday life? Dentists sometimes need to determine the shape of the bite of the patient's teeth. Having rightly decided that all the unpleasant and time-consuming work should be done by a computer, the American dentist W. Mannes invented a sensor that not only encodes bite information and writes it to a computer disk, but also shows on its screen the sequence of teeth closing and even the force of their compression. The sensor is a plastic plate, inside of which there is a silver mesh, squeezing the sensor with his teeth, the patient reduces the distance between its wires, and the computer monitors and processes the information entering it according to the appropriate program.
