The history of computers dates back to ancient times, but the origins of modern computers can be traced back to the beginning of the 20th century. Here are the main milestones in the history of computer development:
1837: Charles Babbage designed a mechanical computer called the Difference Machine.
1937: Alan Turing published an article on the world, proposing the concept of a universal Turing machine, which became the theoretical basis of modern computers.
1941: Konrad Joff introduced the concept of stored programs, laying the foundation for the development of computers.
1943: The ENIAC computer was born, the first electronic computer used to perform complex mathematical calculations and research.
1951: The first commercial computer, UNIVAC I, was put into service to process U.S. Census data.
1958: Jack Killlick and Robert Noyce invented the integrated circuit, which integrates multiple transistors onto a single chip, making computers smaller, faster, and more reliable.
1971: Intel introduced the first microprocessor, which integrated all the features of the processor and ushered in the era of the personal computer.
1981: IBM launched the first personal computer, the IBM PC, becoming the market leader in personal computers.
1990s: The performance, functionality, and popularity of personal computers increased dramatically, and technologies such as Windows operating systems, the Internet, and multi-** appeared.
In general, the history of computers can be seen as the development of technologies such as the modern personal computer and the Internet, from the vast array of mechanical computing devices to the small electronic computers. With the continuous advancement of technology, computers play an increasingly important role in social and economic life.

I'm not going to talk about those tirades, let's talk about personal understanding.
First of all, let's talk about the emergence of underwater computer networks.
The appearance of computer networks is a sign that people can better realize resource sharing, avoid a lot of repetitive work, repetitive wheels, things we don't understand, there have been predecessors to do, at this time we can share the fruits of other people's labor through computer networks to accelerate the development of human civilization (PS: For example, RMS promotes GNU plan, this series is inseparable from computer networks).
Then let's talk about the significance of the emergence of microcomputers.
The advent of the microcomputer has several important significance.
a.The progress and innovation of industrial technology (without the support of industrial technology, the era of microcomputer is impossible).
PS: The typical representative is the emergence of large-scale, ultra-large-scale integrated circuits.
b.Walk into the civilian grade (if it weren't for the emergence of microcomputers, don't tell me that every family would buy a machine the size of a house like Youliang ENIAC, whether it is land occupation, portability, or side costs, or performance are hard injuries).
c.Portability and so on, not much else.
Note: The emergence of microcomputer marks the innovation of industrial technology, and the significance for development is to promote civilian facilities, further develop human civilization, and accelerate the pace of development of human civilization (such as modern smart phones, which are the products of the emergence of microcomputers).
If you are still a junior high school student, there is one word - "back". No matter how good or bad your history is, it is all your back, and it has nothing to do with whether your history is good or not. >>>More

The third year of junior high school. That should be an open-book exam Junior high school history is very easy to learn In the third year of junior high school, the teacher will definitely ask the students to buy a reference book. Read more of the things in the book. >>>More
Endorsement. It's all in the books. Just do it.
Read more history books, not just textbooks, but other books. I don't know what grade you're in, if you have time, you can try to read the general history but it takes more time, although my current history grades are better, but I only read less than half of the thick general history, if it's to cope with the exam, I still prefer to do more questions, which is beneficial to the cultivation of the feeling of history answering, sometimes even if you can't do this knowledge point, you can also cover the point. Personally, I think that it is not achieved overnight, it is a process of accumulation, just like language. >>>More
