integral scheme appeared in the world.
1971 – Ted Hoff invented a microprocessor –
“a computer on one crystal” -4004
1973 – IBM issued the first hard disk
1974 –IBM began the production of the
super fast computer with the parallel countings.

9. 1979 – appeared the first electronic table VisiCalc for business counting on the personal computer.
1980 – “Microsoft” received the license on
QDOS, redo this operating system and won the contract on its delivery for the new personal computer IBM
1980 – “Winchester”, the first micro hard disk
with the size of 5,25 inches was in the sale.

10. 1981 – IBM issued the first personal computer.
Computer “Xerox Star” was sold for
USA dollars. It was equipped with WIMP
system, the previous of interface “click and
drag”. But the project came to grief.
1982 – The first IBM

12. What is a computer? Is it a being living or a machine?

13. 2. What is Internet?
Computer link appeared to join parts of machines and let their users to exchange some facts.
Later there were adopted some agreements which were named
protocols for exchanging of materials inside the net.
A system of addresses was designed in 1980 and it gave an opportunity for every computer to join with other different computers on the net.
The Internet began to form.
The possibility of working on the PC ( personal computer) using
such enclosure as Internet ( WORLD WIDE WEB- WWW ), electronic commerce and mail changed our life, work and business.

14. 3.What is ?
It is an electronic mail which uses Internet for transmission of messages between users with unique addresses.
Messages are followed by the mail servers on their way until they rich the need addresses.
