Computer or electronic devices whose primary function is to receive data, processed, and then presented as the final user, as it plays an important role in our lives, whether in the field of teaching, or work, or design, and others, have been the first goal of his creation it is to perform calculations and store, where the industry went through many stages until it reached the form in which it is now, and Snarafkm in this article to the stages of development of a computer.
Stages of the evolution of the form of computer
Stage vacuum valves
In the years between 1951 and 1957 was created a computer UNIVAC, which is used for scheduling population statistics, which consists of vacuum tubes, a glass vacuum tubes can pass the power supply without the need for a mechanical adapter, a large size, heavy weight, low speed , as well as the need for heating before its work, which consume large amounts of electric power, and the computers at this stage, using the language of the machine, so that the computer instructions are present on a series of numbers body, and formed the CPU in these computers on: unit data processing unit, programmed control, the units on the main Vachtmmelt unit and computer logic, control unit, main memory, and characterized by computers at this stage complex.
In the years between 1959 and 1965 it has been replaced by vacuum tubes Baltranzstorat, which is a component that allows the passage of electrical energy in a specific direction, while at the same time to turn off the electrical power flow in the other direction, and used in these computers magnetic disks for storage, in addition to languages instead of programming languages Avatar, is the word in these computers is the basic unit of information, are organizing information in the words of a length of 36 cell binary, as these words are stored in locations in memory "215", and use this type of computers in universities, and business.
Phase electric circuit
In the years between 1965 and 1970 has been making integrated electrical circuits of silicon chips, which is a semiconductor material pure is added impurities to precisely which leads to the production of capacitors and transistors, resistors, these computers were used byte as a unit data can be stored in the site of memory locations, and treatment when necessary.
Integrated Circuits stage
Smart computers recently started to appear, has been characterized by high their efficiency, and the multiplicity of functions, small sizes and different designs.
