civilization during the past 60 years and had profound

social, economic and scientific effects. Still humans are just beginning to use the potential of computers. Our future progress will strongly depend on the development of computing technologies, it is important to clearly see the their possibilities.
The development of computing technologies depends primarily on the general technological level, available production methods and the market demand for computing.

abacus.
Image 2 – The Suan Pan - Chinese abacus.

The Abacus - is a calculating tool used primarily for performing arithmetic processes. Abacus is a beginning of development of computer technologies .

slide rule.
The Slide Rule - is a mechanical analog

computer. The slide rule is used primarily for multiplication and division, and also for functions such as roots, logarithms and trigonometry.

Calculator or "Pascaline". This calculating machine could add and

subtract two numbers directly and multiply and divide by repetition.

card.
A punched card (punch card, IBM card, or Hollerith

card) is a piece of stiff paper that contains digital information represented by the presence or absence of holes in predefined positions.

machines.
The Analytical Engine was a proposed mechanical general-purpose computer

designed by English mathematician Charles Babbage.

An artistic representation of a Turing machine.
A Turing machine

is a hypothetical device that manipulates symbols on a strip of tape according to a table of rules. Despite its simplicity, a Turing machine can be adapted to simulate the logic of any computer algorithm, and is particularly useful in explaining the functions of a CPU inside a computer.

Konrad Zuse and his Z3.
The Z3 was an electromechanical

computer designed by Konrad Zuse. It was the world's first working programmable, fully automatic digital computer.

ENIAC.
ENIAC was the first electronic general-purpose computer. He was

designed to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory.

SSEM “Baby”.
The Manchester Small-Scale Experimental Machine (SSEM), nicknamed Baby,

was the world's first stored-program computer. He ran its first program on 21 June 1948.

(1937-1955) - is computers that used vacuum tubes as

switching elements.

computers (1954-1962) - is computers that used transistors. Transistor

was invented in 1947. By 1965 second-generation computers were used by many large companies.

Model 30.
3rd generation of computers (1964-1973) was based on

the integrated circuit (computer chip), developed in 1958. First computers of the new generation became available in 1965.

generation of computers, based on a microprocessor, appeared in

1972, just one year after the first microprocessor was created.
