Question 1: How to check which year the computer was bought? Download a Master Lu and then test it. It will show the date of manufacture and the time of use of each hardware in your computer.

Question 2: What year do you think your computer was configured? I don't understand what configuration you are asking.

View windows Version-Desktop-My Computer-Right Click-Properties-Open it and you will see it.

Check the factory date of the computer-the back of the desktop and the bottom of the notebook-and check the product label, which has relevant information. If there is no production date, look at the bar code and check it on the computer official website.

Check the hardware configuration-the most detailed and simplest method-install one of 360 driver master, windows optimization master, Master Lu, driver wizard and so on. After a close-up hardware scan, you will see everything.

Question 3: What year do you think the computer is? If it is a brand machine, there may be production date information on the fuselage label. If it is an assembly machine, it is difficult to judge. You can only make a rough judgment based on the model of spare parts.

Question 4: When do you think the computer was assembled?

The accessories on the computer are all marked. Look, this is the kind of small rectangular label with the sales time on it. Or according to the upstairs, you can see the factory time of Master Lu's accessories, but Master Lu's inspection time is generally much earlier than the sales time.

Brand machine:

Look at the quality certificate. Regular businesses have filled in the quality certificate. If not, you can go to official website to inquire about its sale and factory date.

Question 5: When do you think others bought some self-contained test software, such as CPU-Z, GPU-Z, AIDI64, etc? To test whether the hardware meets the seller's requirements, if so, go to the computer website (Zhongguancun Online, Pacific Computer, etc. ) Look at the hardware quotation. If it is too cheap relative to the overall price of hardware, be careful.

Question 6: When did computers appear? February 1946, 14, at Moore School of Electrical Engineering, University of Pennsylvania, there was a festive atmosphere everywhere. Many guests come here with excitement because they will attend the unveiling ceremony of the first modern electronic computer in human history. What is presented to people is a strange-looking and glowing monster. It is the world's first modern electronic computer "ENIAC". This behemoth covers an area of 170 square meters and weighs 30 tons. At the unveiling ceremony, "Eniac" performed its unique trick-completing 5000 addition operations and 500 multiplication operations in 1 second respectively, which was more than 1000 times faster than the fastest relay computer at that time. This perfect appearance made the guests applaud. However, who knows, in the process of the birth of this behemoth, how many people have devoted countless efforts to it! 193 1 year, Fannie Bush invented a counting machine that can solve the difference program. This machine can solve some complicated difference programs that are a headache for mathematicians and scientists. 1935, IBM (International Business Machines Corporation) introduced IBM 60 1 ",which is a punch card machine with arithmetic components, and can calculate the multiplier within 1 second. It plays a great role in scientific computing and commercial computing. A total of 1500 units were manufactured. 1937, alan turing put forward the concept of "universal machine", which can execute any algorithm, and formed the basic concept of "availability". Turing's concept is superior to other inventions of the same type because he uses the concept of symbol processing. 10 In October, John Vincent Atansov and john berry made a 16-bit adder. This is the first machine to calculate with vacuum tubes. 1939, Zuze and Scherer made V2 "(later called Z2). This machine follows the mechanical storage of Z 1 and adds a new arithmetic component using relay logic. But when Zuze finished the draft, the plan was suspended for a year. In 1939-40, Schreyer completed the 10 bit adder with vacuum tube and the memory with neon lamp. 1June, 940, Bell Labs, Samuel Williams and Stibitz completed a machine that can calculate complex numbers, which was called "plex Digital Calculator" and later renamed as I (Model I Relay Calculator). It uses telephone switches as logic elements: 145 circuit breaker and 10 bar switch. Numbers are represented by "plus 3BCD". In September of the same year, the teletypewriter was installed at a math conference and connected from New Hampshire to new york. 1940, Zuse finally completed Z2, which is better than the operation, but not very reliable. 194 1 in the summer of, atanasoff and Berry completed a calculator specially designed for solving linear equations, which was later called ABC (atanasoff Berry Computer). It has a 60Hz 50-bit memory, which is installed on two rotating drums in the form of capacitors. The clock speed is 194 1 February, and Zuse completed V3 "(later called Z3), which is the first computer that can be programmed to run. It also uses floating-point operation, 7-bit exponent, 14 mantissa and a symbol. The memory can store 64 words, so 1400 circuit breakers are needed. It has more than 1200 arithmetic and control elements, and is programmed >:>

Question 7: How to find out when the computer was bought? Check the details of computer configuration with Master Lu, and you can also see how long it took.

Question 8: How to check the production year of the computer? I. Click "Start", find "Run", and then click "Run".

Second, enter cmd in the operation.

Third, the dos interface will appear after confirmation, and then you can enter the debug confirmation;

Fourth, after entering the debugging and compiling mode. Enter the command Gongffff: 00 to view the data in this space, which is the production date of your computer;

5. The data after 5.ffff: 00 lines is the production date of your computer. 10/07/ 1 1 means 20 1 1, 10,07 in English. See figure:

Question 9: What year is the computerized flat knitting machine? What the hell?

Question 10: When was the first computer in the world?

Enica

The first electronic computer was made shortly after the Second World War. At that time, with the development of artillery, trajectory calculation became more and more complicated, and some original computers could not meet the requirements of use, so a new fast calculation tool was urgently needed. In this way, with the efforts of some scientists and engineers, on the basis that electronic technology has shown the functions of counting, calculation, transmission and storage control, electronic computers have emerged. The first electronic computer in the world was named ENIAC, which was successfully developed by eckert and others of the University of Pennsylvania in 1946. It is equipped with more than 18 000 electron tubes and a large number of resistors and capacitors, and it has been operated by electronic circuits for the first time. Eniac can do 5000 additions or 400 multiplications per second. If the 40-point trajectory was calculated by the fastest electromechanical computer at that time, it would take two hours, while Eniac only took three seconds, which was really a great achievement at that time. However, Eniac is not perfect. In fact, it has no memory, only a register made of electron tubes, which can only store 10 bits. When other topics need to be changed, it is time-consuming to re-weld the connection. Since the birth of the first electronic computer, although it has only a history of about 40 years, it has undergone four generations of changes. The first generation is electron tube computer, the second generation is transistor computer, the third generation is integrated circuit computer, and the fourth generation is large-scale integrated circuit computer. At present, it is transitioning to the fifth generation-thinking machine, which shows people that human beings will create a bright future for thinking machines.
