电脑发展历史作业

计算机历史与发展英语作文英文回答：The History and Evolution of Computers.The history of computers dates back to the early days of human civilization. The first known computing devices were the abacus and the astrolabe, which were used by the ancient Greeks and Chinese for mathematical calculations and astronomy.In the 16th century, the invention of the mechanical calculator by Blaise Pascal marked a significant advancement in computing technology. This device could perform basic arithmetic operations, such as addition, subtraction, multiplication, and division.The 19th century saw the development of more advanced computing machines, such as the Analytical Engine by Charles Babbage. This machine was capable of performing awide range of mathematical operations and is considered to be the first mechanical computer.In the 20th century, the invention of the electronic computer revolutionized the field of computing. The first electronic computer, the ENIAC (Electronic Numerical Integrator and Computer), was developed by John Atanasoff and Clifford Berry at the University of Pennsylvania in 1943.The ENIAC was a massive machine that weighed over 30 tons and contained over 18,000 vacuum tubes. It was capable of performing complex calculations at a speed of 5,000 operations per second.The development of transistors in the late 1940s and early 1950s led to the creation of smaller and more powerful computers. The first transistorized computer, the TX-0, was developed by MIT in 1956.The 1960s and 1970s saw the development of integrated circuits (ICs), which allowed multiple transistors to bepacked onto a single silicon chip. This advancement led to the creation of even smaller and more powerful computers.The 1980s saw the release of the first personal computers (PCs), which brought computing power toindividual users for the first time. The IBM PC, releasedin 1981, was a particularly influential model that popularized the PC concept.The 1990s and early 2000s saw the development of the World Wide Web and the Internet, which connected computers around the world and revolutionized the way people communicated and accessed information.The 21st century has seen the rise of mobile computing, cloud computing, and artificial intelligence (AI). Mobile devices, such as smartphones and tablets, have become ubiquitous, providing users with access to computing power and connectivity on the go.Cloud computing allows users to access and store data and applications over the Internet, rather than on theirown devices. This provides greater flexibility and scalability.AI is a field of computer science that focuses on developing intelligent systems that can perform tasks typically requiring human intelligence, such as learning, problem-solving, and decision-making.The development of computers has had a profound impact on society. Computers have revolutionized the way we work, communicate, learn, and access information. They have also played a major role in scientific research, engineering, medicine, and many other fields.As computing technology continues to evolve, it is likely to have an even greater impact on our lives in the years to come.中文回答：计算机的历史与发展。

电脑的发展和历史《电脑的发展与历史：一场奇妙的科技之旅》我呀，对电脑可有着不少的故事呢。

记得小时候，我去邻居叔叔家，第一次见到那台大屁股电脑。

那电脑可笨重了，像个大箱子似的蹲在桌子上。

叔叔坐在电脑前，噼里啪啦地打着字，我就好奇地凑过去问：“叔叔，这是啥呀？咋这么大个儿呢？”叔叔笑着说：“这是电脑，可神奇了，能做很多事呢。

”我瞪大了眼睛，看着那闪着光的屏幕，心里满是疑惑。

其实呀，电脑的发展那可真是一部长长的故事书。

最开始的时候，那些早期的电脑简直就是庞然大物。

听说那些科学家们为了让电脑能计算复杂的数学问题，那是费尽了心思。

就像一群探险家在黑暗中摸索着前进，每一步都充满了未知。

那时候的电脑，只有少数人能接触到，而且操作起来也特别复杂。

后来呢，我上中学了。

学校里有了电脑课。

老师站在讲台上，对着那台电脑说：“同学们，这电脑现在可越来越重要了，大家要好好学。

”我和同学们都围在电脑周围，小心翼翼地摸着鼠标和键盘，就像摸着什么稀世珍宝一样。

有个同学好奇地问老师：“老师，这电脑咋越来越小了呢？”老师哈哈一笑说：“这就是科技的发展呀，就像人长大了会变得越来越聪明一样，电脑也在不断进步。

”电脑的发展速度可真快。

没过多久，电脑就走进了千家万户。

我家也买了一台。

我兴奋地坐在电脑前，捣鼓着各种软件。

我和朋友聊天的时候还说：“你看这电脑，现在都能让我们随时聊天了，以前想都不敢想。

”朋友也激动地说：“是啊，还能在网上看各种电影、电视剧呢。

”那时候，我们就像发现了新大陆一样，整天在电脑的世界里探索。

再看看现在，电脑变得又轻薄又强大。

我有个搞设计的朋友，他拿着他那台超轻薄的笔记本电脑，向我炫耀说：“你看这电脑，我带着它到处跑都不费劲，而且处理那些复杂的设计图可快了。

”我羡慕地说：“这可真好啊，现在的电脑真是方便极了。

”从那些巨大的、只能做简单计算的初代电脑，到现在小巧玲珑却功能强大的电脑，这一路走来，就像是一场奇妙的旅行。

这中间有无数的科学家、工程师们的心血。

The Origin and Evolution of Computers The journey of computers, from their humble beginnings to the sophisticated machines we have today, is a fascinating tale of technological advancement and innovation. Tracing back the origin of computers, we find ourselves in the mid-19th century, when the concept of programmable machines started to take shape. However, it was the late 20th century that witnessed the birth of the modern computer era, which has revolutionized the way we live and work.The earliest precursors of computers were mechanical calculators, designed to perform basic arithmetic operations. These machines, like the abacus and the slide rule, were used for centuries to assist in mathematical computations. However, it was the invention of the first electronic computer, ENIAC (Electronic Numerical Integrator and Computer), in 1945, that marked a significant milestone in the history of computing.ENIAC was a bulky machine, occupying an entire room and employing thousands of vacuum tubes. Despite its size and limitations, it was capable of performing complexcalculations much faster than any human or previous machine. This groundbreaking invention laid the foundation for the development of more compact and powerful computers in the following decades.The advent of transistors in the late 1940s and the subsequent development of integrated circuits in the 1960s further miniaturized computers, making them more accessible and affordable. This led to the emergence of personal computers in the 1970s and 1980s, which revolutionized the computing industry. These machines, initially targeted at hobbyists and enthusiasts, soon became a household item, allowing individuals to access and process information with unprecedented ease.The evolution of computers did not stop there. The advent of the internet in the 1990s opened up a new era of connectivity and information sharing. Computers became not just tools for computation but also gateways to a global network of knowledge and resources. The rise of cloud computing, big data analytics, and artificial intelligence has further expanded the capabilities of computers, makingthem indispensable in fields like healthcare, education, business, and science.Today, computers have penetrated every aspect of our lives, from the smartphones we carry in our pockets to the supercomputers that drive complex scientific research. They have made it possible for us to communicate instantly, access vast amounts of information, and automate tasks that were once beyond our capabilities.Looking ahead, the future of computing seems asexciting and unpredictable as its past. With the development of quantum computing, neuromorphic computing, and other emerging technologies, we can expect computers to become even more powerful and efficient. They will continue to transform the way we live and work, opening up new possibilities and challenging our imagination.In conclusion, the origin and evolution of computers represent a remarkable journey of technological progress. From their humble beginnings as simple calculating machines to the sophisticated, interconnected systems we have today, computers have revolutionized the world. As we move into the future, the potential of computing remains vast andunexplored, promising new frontiers of discovery and innovation.**电脑的起源与发展**从电脑的雏形到我们今天所拥有的精密机器，其发展是一段引人入胜的技术进步与创新的故事。

电脑发展过程|电脑发展过程作文素材-作文初中作文高中作文小学作文作文网第一台计算机ENIAC1946年2月15日，世界上第一台通用电子数字计算机埃尼阿克（ENIAC）宣告研制成功。

埃尼阿克的成功，是计算机发展史上的一座纪念碑，是人类在发展计算技术的历程中，到达的一个新的起点。

埃尼阿克计算机的最初设计方案，是由36岁的美国工程师莫奇利于1943年提出的，计算机的主要任务是分析炮弹轨道。

美国军械部拨款支持研制工作，并建立一个专门研究小组，由莫奇利负责。

总工程师由年仅24岁的埃克特担任，组员格尔斯坦是位数学家，另外还有逻辑学家勃克斯。

埃尼阿克共使用了18000个电子管，另加1500个继电器以及其它器件，其总体积约90立方米，重达30吨，占地170平方米，需要用一间30多米长的大房间才能存放，是个地地道道的庞然大物。

这台每小时耗电量为140千瓦时的计算机，运算速度为每秒5000次加法，或者400次乘法，比机械式的继电器计算机快1000倍。

当埃尼阿克公开展出时，一条炮弹的轨道用20秒钟就算出来，比炮弹本身的飞行速度还快。

埃尼阿克的存储器是电子装置，而不是靠转动的鼓。

它能够在一天内完成几千万次乘法，大约相当于一个人用台式计算机操作40年的工作量。

它是按照十进制，而不是按照二进制来操作。

但其中也用少量以二进制方式工作的电子管，因此机器在工作中不得不把十进制转换为二进制，而在数据输入、输出时再变回十进制。

埃尼阿克最初是为了进行弹道计算而设计的专用计算机。

但后来通过改变插入控制板里接线方式来解决各种不同的问题，而成为一台通用机。

它的一种改型机曾用于氢弹的研制。

埃尼阿克程序采用外部插入式，每当进行软件中心一项新的计算时，都要重新连接线路。

有时几分钟或几十分钟的计算，要花几小时或1-2天的时间进行线路连接准备，这是一个致命的弱点。

它的另一个弱点是存储量太小。

1996年2月15日，在埃尼阿克问世50周年之际，美国副总统戈尔在宾夕法尼亚大学举行的隆重纪念仪式上，再次按动了这台已沉睡了40年的庞大电子计算机的启动电钮。
