The main logic component of the first generation of computers was "electron tubes". The first generation computer was a tube computer; in terms of hardware, the logic components used vacuum tubes, the main memory used mercury delay lines, cathode ray oscilloscope tube electrostatic memories, magnetic drums, and magnetic cores, and the external memory used magnetic tapes.

The main logic components of the first generation of computers used " Electron Tube".

The first generation computer was a vacuum tube computer. Its main features were the use of vacuum tubes as basic electronic components, which were large in size, high in power consumption, short in life, low in reliability and high in cost; the memory used mercury delay lines. During this period, there was no system software and machine language and assembly language were used for programming. Computers can only be used in a few cutting-edge fields, generally used for scientific, military and financial calculations.

Although the first generation of electronic computers seems to people today to be quite clumsy, large in size, expensive to build, and difficult to operate, it was it that opened up the road to computer development and brought about vigorous changes in human social life. The first generation of electronic computers refers to the electronic computers from 1946 to 1958. At this time, the basic circuit of computers used electron tube structures, and programs transitioned from hand-coded machine instruction programs to symbolic languages. The first generation of electronic computers was the beginning of the revolutionary development of computing tools. The binary system and programs it used Basic technical ideas such as storage laid the foundation for modern electronic computer technology.

Extended information:

The characteristic of the first generation of computers is that operating instructions are compiled for specific tasks. Each machine has its own different machine language, and its functions are affected by Limited and slow. Another distinctive feature is the use of vacuum tubes and magnetic drums to store data. The first electron tube computer (ENIAC) occupied an area of ​​170 square meters, weighed 30 tons, and had 18,000 electron tubes. It was calculated in decimal system and performed 5,000 operations per second. Due to the large size of the electron tubes, high power consumption, severe heat generation, short lifespan, and poor power utilization, the first electron tube computer (ENIAC) The memory has the disadvantages of low efficiency, fragile structure and the need for a high-voltage power supply. The memory uses mercury delay lines. During this period, there was no system software and machine language and assembly language were used for programming. Computers can only be used in a few cutting-edge fields, generally used for scientific, military and financial calculations. Most of its uses have been basically replaced by solid-state device transistors. However, electron tubes have strong load capacity, better linear performance than transistors, and better working characteristics than transistors in high-frequency and high-power fields, so they still continue to play an irreplaceable role in some places (such as high-power radio transmitting equipment).

As the first generation of computers, it is a type of computer that connects the past and the next. Promote the development of computers.
