2. The history of computer

the birth and development of modern computer before the advent of modern computer, the development of computer has gone through three stages: mechanical computer, electromechanical computer and electronic computer

as early as the 17th century, a group of European mathematicians began to design and manufacture digital computers that perform basic operations in digital form. In 1642, Pascal, a French mathematician, made the earliest decimal adder by using a gear transmission similar to clocks and watches. In 1678, Leibniz, a German mathematician, developed a computer to further solve the multiplication and division of decimal numbers

British mathematician Babbage put forward an idea when he made the model of difference machine in 1822. One arithmetic operation at a time will develop into a certain complete operation process automatically. In 1884, Babbage designed a program-controlled universal analyzer. Although this analyzer has described the rudiment of the program control computer, it can not be realized e to the technical conditions at that time< During the more than 100 years since Babbage's idea was put forward, great progress has been made in electromagnetics, electrotechnics and electronics, and vacuum diodes and vacuum triodes have been successively invented in components and devices; In terms of system technology, wireless telegraph, television and radar were invented one after another. All these achievements have prepared technical and material conditions for the development of modern computer< At the same time, mathematics and physics are developing rapidly. In the 1930s, all fields of physics experienced the stage of quantification. The mathematical equations describing various physical processes, some of which were difficult to solve by classical analysis methods. As a result, numerical analysis has been paid attention to, and various numerical integration, numerical differentiation, and numerical solutions of differential equations have been developed. The calculation process has been reced to a huge amount of basic operations, thus laying the foundation of modern computer numerical algorithm

the urgent need for advanced computing tools in society is the fundamental driving force for the birth of modern computers. Since the 20th century, there have been a lot of computational difficulties in various fields of science and technology, which has hindered the further development of the discipline. Especially before and after the outbreak of the Second World War, the need for high-speed computing tools in military science and technology is particularly urgent. During this period, Germany, the United States and the United Kingdom started the research of electromechanical computer and electronic computer almost at the same time<

Giuseppe in Germany was the first to use electrical components to make computers. The fully automatic relay computer Z-3, which he made in 1941, has the characteristics of modern computer, such as floating-point counting, binary operation, instruction form of digital storage address and so on. In the United States, the relay computers mark-1, mark-2, model-1, model-5 and so on were made successively from 1940 to 1947. However, the switching speed of the relay is about one hundredth of a second, which greatly limits the computing speed of the computer

the development process of electronic computer has experienced the evolution from making components to whole machine, from special machine to general machine, from "external program" to "stored program". In 1938, the Bulgarian American scholar atanasov first made the computing unit of the electronic computer. In 1943, the communications office of the British Foreign Office made the "giant" computer. This is a special cryptanalysis machine, which was used in the Second World War< In February 1946, ENIAC, a large-scale electronic digital integrator computer, was developed by Moore College of the University of Pennsylvania in the United States. At first, ENIAC was also specially used for artillery trajectory calculation. Later, it was improved many times and became a general-purpose computer capable of various scientific calculations. This computer, which uses electronic circuit to perform arithmetic operation, logic operation and information storage, is 1000 times faster than relay computer. This is the first electronic computer in the world. However, the program of this kind of computer is still external, the storage capacity is too small, and it has not fully possessed the main characteristics of modern computer

the new breakthrough was completed by a design team led by mathematician von Neumann. In March 1945, they published a new general electronic computer scheme of stored program - electronic discrete variable automatic computer (EDVAC). Then in June 1946, von Neumann and others put forward a more perfect design report "preliminary study on the logical structure of electronic computer devices". From July to August of the same year, they taught a special course "theory and technology of electronic computer design" for experts from more than 20 institutions in the United States and Britain at Moore college, which promoted the design and manufacture of stored program computers< In 1949, the Mathematics Laboratory of Cambridge University in England took the lead in making EDSAC; The United States made the eastern standard automatic computer (SFAC) in 1950. At this point, the embryonic period of the development of electronic computer came to an end, and the development period of modern computer began

at the same time of creating digital computer, we also developed another kind of important computing tool analog computer. When physicists summarize the laws of nature, they often use mathematical equations to describe a process; On the contrary, the process of solving mathematical equations may also adopt the physical process simulation method. After the invention of logarithm, the slide rule made in 1620 has changed multiplication and division into addition and subtraction for calculation. Maxwell skillfully transformed the calculation of integral (area) into the measurement of length, and made the integrator in 1855< Fourier analysis, another great achievement of mathematical physics in the 19th century, played a direct role in promoting the development of simulators. In the late 19th century and the early 20th century, a variety of analytical machines for calculating Fourier coefficients and differential equations were developed. However, when trying to popularize the differential analysis machine to solve partial differential equations and use the simulator to solve general scientific calculation problems, people graally realize the limitations of the simulator in the aspects of universality and accuracy, and turn their main energy to the digital computer

after the advent of electronic digital computer, analog computer still continues to develop, and hybrid computer is proced by combining with digital computer. Simulators and mixers have become special varieties of modern computers, that is, efficient information processing tools or simulation tools used in specific fields
since the middle of the 20th century, the computer has been in a period of high-speed development. The computer has developed from a hardware only system to a computer system which includes three subsystems: hardware, software and firmware. The performance price ratio of computer system is increased by two orders of magnitude every 10 years. The types of computers have been divided into microcomputers, minicomputers, general-purpose computers (including giant, large and medium-sized computers), and various special computers (such as various control computers and analog-to-digital hybrid computers)
computer devices, from electron tubes to transistors, from discrete components to integrated circuits to microprocessors, have made three leaps in the development of computers< In the period of electron tube computer (1946-1959), computers were mainly used for scientific calculation. Main memory is the main factor that determines the appearance of computer technology. At that time, the main memory included mercury delay line memory, cathode ray oscilloscope electrostatic memory, magnetic drum and magnetic core memory, which were usually used to classify computers.

6. Memory was originally sung by Elaine Paige, who sang it when the cat premiered

if someone asks, how do you know about memory? I believe 99% of people will say that it started with the version of Barbara Streisand, which is the earliest version of memory that we can get to know. When we didn't know much about cat, we were fascinated by this weeping song and became a loyal supporter of Barbara, I don't remember its original singer Elaine Paige very much. No one would say that Barbara is beautiful. When she was interviewed, she just called herself "an actress who can sing". However, she has made great achievements in the fields of pop songs, classical songs, singing, stage plays and even movies. Although she has not participated in the main performance of cat, no one can deny her wonderful performance of memory

the fragrance of tea accompanies me forever... A group of noble cats recommend who will go to heaven on Sunday. They all talk about their rich life, luxurious life and the talent of their owners. Suddenly, a stray cat comes to tell us how desolate and colorful their plain and wandering life is, and how firm their faith is, She also sang the classic "memory" with emotion, which brought the whole opera to a climax. It was in this quiet song that she stepped towards heaven step by step, and all the cats watched her go with reverence...

midnight, not a sound from the pavement at midnight
has the moon lost her memory? Whether the moon has lost her memory
she is smiling alone in the lamplight
the with leaves collected at my feet
and the wind begins to moan

memory, All alone in the moonlight
I can smile at the old days
I was beautiful then
I remember
the time I knew what happiness was
let the memory live again A street lamp
looks like it's knocking on a fatalistic warning
someone whispers
and a street lamp chatters
and soon it will be morning

day, I must wait for the sunrise, I have to wait for the sunrise
I must think of a new life
and I must n & quot; T give in I can't give up
when the day comes
tonight will be a memory too Another night is over
another day is dawning

touch me, it & quot; S so easy to leave me, it's so easy to leave me,
all alone with my memory
of my days in the sun
if you touch me if you approach me
you & quot; Ll understand what happiness is
look a new day has been
7.

You warm my years

we all have a place where we can live when we are tired; A place with the best love in the world; A place full of warmth that doesn't need to be big or beautiful

we have a home

Each of us is looking for a place to go back; Looking for a place full of light; Looking for a place to let us go

we found a home

From the time I can remember, my father seldom went home. Most of it was spent with my mother. This inevitably made me vague about my father's face. But I think I am happy, I have an emotion, a lot of people can not feel the emotion, and this kind of emotion, deposited in my home

my mother is just an ordinary woman, a hardworking and unrequited giver. When I was a child, my mother always told me the truth of life in my ear, and I didn't say a word to my mother's loving advice. Whenever I made a little success in my study, my mother always seemed more happy than me. Every time I asked her why she was so happy, she always laughed and said nothing. In retrospect, every bit of the past appeared in my mind like a movie...

I don't know when my mother's hair was white. I know that I am anemic, but I still insist on cleaning the house to make it comfortable and tidy forever. I know that my hand is allergic to washing powder, but I don't care about putting my hand into the water to wash clothes

maybe I don't know. Every time my mother told me to be careful on the way when the school organized to go out to play, there was no disguised worry on my face

maybe I don't know how repentant and miserable my mother is after each time she beat me and scolded me

Maybe I don't know how anxious and nervous my mother was when I was sent to the hospital after I fell into the water that year

However, with the passage of time, I have changed from a little girl who is ignorant to a girl who can understand others. I understand the mother's love, understand the meaning of "love", understand that love does not need a reason

speaking of my father, he always laughs in front of me, which seems to drive me and make me always smile in front of anyone. The classmate once described me like this, "as long as there is a place where you are, the little troubles stored in the body will be blown to the ground and die!" But as soon as my father became serious, he seemed to be a different person. As soon as he pulled his eyebrows, opened his eyes and closed his mouth, he began to teach me every word. As for me, I nodded my head once or not

I understand that this is my father's love. Unlike maternal love, it is secret and needs our careful attention

There is a kind of emotion in home, which always helps you when you are in despair. It can always warm you, warm me, and give you a kind of strength to persist

Home, the place I love most, I will study hard with my parents' expectation and go home with success in the future

8. "Books are the ladder of human progress". From ancient times to the present, books have been sought after by countless people, and they are inseparable from us

the years are long and boring. When I was a child, I always felt that my life was boring and cold. I lacked a torch to light me up. Only when I found that "the man was in the dim light", it was book

books are good teachers and helpful friends. They accompany my growth and record every bit of my life

when I was very young, I was illiterate, so I asked my parents to read it to me. With the passage of time, I have grown into a young man with a little literary talent, and the number of words I knew graally increased, and naturally more books I read. From the journey to the west, I read about the difficulties and obstacles encountered by the four monks and disciples of Tang Dynasty; From the romance of the Three Kingdoms, I read out the heroes in troubled times. From Chinese literature to world literature, reading how steel was tempered, I read out Paul's revolutionary ideal of never falling behind. Read "gone with the wind", I always remember the last sentence in the article: "anyway, tomorrow is a new day." Since ancient times, from the east to the west, books have always accompanied me to grow day by day, telling me thousands of truth, is my lifelong teacher, is my inseparable friend

"the influence of people is short and weak, and the influence of books is wide and far-reaching." This is a famous saying of Russian poet Pushkin. A book will be read by thousands of people, and everyone will pass on the spirit of the book like a spark. Therefore, the book will affect the lives of thousands of people

the merciless years are blessed with books. In these merciless and long years, books always light up our way forward, making the merciless years warm and the long years full. A book is like a gentleman who conveys his good conct to us without any harm

may we move forward in the sea of books

may we have our own space in the world of books

may we soar freely in the sky of books and fly to a wider world.
