Computers evolved from tubes, transistors, and integrated circuits, and what was the development pro

The history of the development of computers, hello everyone, welcome to the computer knowledge popularization and application classroom. Today I want to talk to you about some knowledge about the development of computers. Knowledge of tubes, transistors, integrated circuits and VLSI circuits is included.

The answer is D, and these questions can be guessed from the title.

Kiss!!! The development process of computers from electron tubes to integrated circuits can be summarized into the following stages:

1.Tube era (1940-1950s): Lingxin's early computers used tubes as the main electronic components, and the tubes were large in size, high in power consumption, and easy to break, which limited the development of computers.

2.Transistor era (1950s-1960s): The advent of transistors has greatly reduced the size and power consumption of computers, and the speed and reliability of computers have also increased.

Representative computers of the transistor era include the IBM 7090 and the DEC PDP-8.

3.The era of integrated circuits (1960s-present): The emergence of integrated circuits has further reduced the size and power consumption of computers, and the speed and reliability of computers have been further improved.

Representative computers in the era of integrated circuits include IBM System 360 and DEC VAX.

In the era of integrated circuits, the development of computers has entered a stage of rapid development, the performance and functions of computers have been continuously improved, and the application fields have also been expanded. With the continuous development of computer technology, computers have become an indispensable and important tool in the modern shaku-mae-wheel society.

The development of computers has gone through the era of electron tubes, transistors, integrated circuits, and large-scale integrated circuits.

Mainframe stage: From the 40s to the 50s of the 20th century, the first generation of electric socks hail hole tube computer through the development process of tube digital computer and transistor digital computer computer, the technology gradually matured. Small Computer Stage:

In the 60s and 70s of the 20th century, the first reduction of the mainframe can meet the information processing requirements of small and medium-sized enterprises.

Microcomputer stage: the 70s and 80s of the 20th century, the second downsizing of the mainframe, 1976 in the United States.

Apple was founded and launched a small computer in 1977 with great success. Client Stage: With the establishment of the first global online booking system in 1964, more than 2,000 booking terminals in the United States at that time were connected together with ** cables, marking the computer entered the client server stage.

Since 2008, the concept of cloud computing has become popular and has been seen as a revolutionary computing model because it has made it possible for supercomputing power to circulate freely over the Internet.

Computers made with transistors as electronic devices belong to the second generation.

Transistor computers refer to computers from the late 50s to the 60s of the 20th century. The host uses semiconductor devices such as transistors, magnetic drums and disks as auxiliary storage devices, and is programmed in algorithm languages (high-level languages), and operating systems begin to appear. Because transistors are used instead of electron tubes, they are very light and the calculation speed is relatively fast, reaching hundreds of thousands of times per second.

The basic logic components of a transistor computer have been changed from electron tubes to transistors, and the internal memory uses a large number of magnetic cores made of magnetic materials, and the external memory uses disks. At the same time, computer software technology has also developed greatly, and the concept of operating system has been proposed; In addition to assembly language, programming languages have also developed ADA, Fortran, COBOL and other high-level programming languages, which greatly improve the work efficiency of computers.

In terms of hardware, transistors are used as logic components and magnetic core materials as memory; In terms of software, high-level program design is used, and in terms of application, it is expanded to data processing and process control.
