Computer, commonly known as computer, is an electronic computer used for high-speed calculation, which can perform numerical calculations, logical calculations, and also has the function of storage and memory.

There are a total of 5 stages of development:

The first stage of development was the era of tube computers. In 1946, the first electronic computer was introduced at the University of Pennsylvania in the United States, and it was designed by Mowkeley Eckert. It covers an area of 170 square meters, 150kw

The speed of computing is not as fast as anyone else, which is a milestone in the history of computer development.

The second stage of development is the computer age of transistors.

The third stage of development is the computer age of integrated circuits and large-scale integrated mode inspection circuits.

The fourth stage of development is the computer age of VLSI circuits.

The fifth stage of development is the era of intelligent weighing and limb computers, which combine the collection, storage, processing, and communication of information with artificial intelligence.

The history of computer development can be divided into four stages: 1854, 1890, 1890, early 20th century, mid-20th century, late 20th century to the present.

The first generation: tube digital machine (1946-1958).

In terms of hardware, the logic element uses a vacuum tube, and the main memory uses a mercury delay line, a cathode ray oscilloscope electrostatic memory, a magnetic drum, and a magnetic core; The external memory is tape. In terms of software, machine language and assembly language are used. The fields of application are mainly military and scientific computing.

The disadvantages are large size, high power consumption, and poor reliability. Slow (typically thousands to tens of thousands of operations per second), expensive, but laid the foundation for future computer development.

The second generation: transistor digital machines (1958-1964).

In terms of software, the application fields of operating systems, high-level languages and their compilers are mainly scientific computing and transaction processing, and they have begun to enter the field of industrial control. It is characterized by smaller size, reduced energy consumption, improved reliability, increased computing speed (generally 100,000 times per second, up to 3 million times), and a significant improvement in performance compared to the first generation computer.

The third generation: integrated circuit digital machine (1964-1970).

In terms of hardware, the logic components are medium- and small-scale integrated circuits (MSI, SSI), and the main memory is still using magnetic cores. On the software side, time-sharing operating systems and structured, scaled programming methods have emerged. It is characterized by faster speed, and the reliability has been significantly improved, ** further declined, and the product has moved towards generalization, serialization and standardization.

The application field began to enter the field of word processing and graphic image processing.

4th Generation: LSI Computers (1970-present).

In terms of hardware, the logic components are large-scale and ultra-large-scale integrated circuits (LSI and VLSI). In terms of software, database management systems, network management systems, and object-oriented languages have emerged. In 1971, the world's first microprocessor was born in Silicon Valley, ushering in a new era of microcomputers.

The application field has gradually moved from scientific computing, transaction management, and process control to the home.

The development of computers can be divided into the following stages:

The Age of Mechanical Calculators (1600s-1940s): The earliest mechanical calculators date back to the 17th century, but it wasn't until the 40s of the 20th century that the advent of electron tubes brought about a major revolution in mechanical calculators.

The Computer Age (1940s-1960s): During World War II, the world's first electronic computer, ENIAC, was born. Since then, with the further development of electron tubes, the speed and storage capacity of computers have also increased dramatically.

The era of integrated circuits (1960s-1970s): With the advent of integrated circuit technology, computer hardware began to become smaller, cheaper, and more reliable. This period gave birth to the world's first microcomputer.

Personal Computer Age (1970s-present): In the 1970s, personal computers began to gain popularity. With the continuous improvement of software and operating systems, the scope and functionality of computers have been greatly expanded.

The Internet Age (1990s-Present): In the 90s of the 20th century, the advent of the Internet dramatically changed the way computers were used. People can communicate and interact with information on a global scale through computers.

Mobile Computing Era (2000s-present): At the beginning of the 21st century, the advent of smartphones and tablets brought computers into the mobile age. People can use computers for work and entertainment anytime and anywhere.

There are many things that can be done by learning computers, but only if the technology is at home. Now is the age of the Internet, and it is certainly not difficult to find a job after graduation.

Network. The direction of the development of computers:

1. Mega-sized. Megacomputing refers to the development of faster, more storage-capable, and powerful supercomputers. The computing power is generally more than 10 billion per second, and the content capacity is more than a few hundred megabytes, and it is mainly used in cutting-edge scientific and technological fields such as astronomy, meteorology, geological and nuclear technology, space shuttles, and satellite orbit calculations.

The technological level of a computer is an important indicator of a country's level of technological and industrial development.

2. Miniaturization. Miniaturization refers to the use of microelectronics technology and VLSI technology to further reduce the size of computers. The miniaturization of computers has become an important direction of computer development, and the advent of a large number of various notebook computers and PDAs is a sign of computing miniaturization.

3. Networking. In this dynamically changing network environment, it realizes the comprehensive sharing of computing resources, storage resources, data resources, information resources, knowledge resources, and expert resources, so that users can enjoy flexible control, intelligent, and collaborative information services, and obtain unprecedented convenience of use.

4. Intelligent. Computer intelligence refers to the ability of computers to simulate human feelings and thought processes. Intelligent research includes simulation recognition, object shape analysis, natural language generation and understanding, games, automatic proof of theorems, automatic programming, expert systems, learning systems, and intelligent robots.
