NC: Network Computer,网络计算机。
MPC: Multimedia1 Personal Computer,多媒体个人电脑。
MMX: 是MultiMedia extensions(多媒体扩展)的缩写,是第六代CPU芯片的重要特点。
MMX技术是在CPU中加入了特地为视频信号(Video Signal),音频信号(Audio Signal)以及图像处理(Graphical Manipulation)而设计的57条指令,因此,MMX CPU极大地提高了电脑的多媒体(如立体声、视频、三维动画等)处理功能。
Intel Pentium 166MHz MMXTM: Intel Pentium是英特尔(Intel)公司生产的“奔腾”CPU。
?意为“Registered”(注册商标)。
166MHz指CPU时钟频率,MHz即Mega Hertz的缩写。
MMXTM 中的TM是“Trade Mark”的简写,意为“注册商标”。
OOP: Object Oriented Programming,面向对象的程序设计。
所谓“对象”就是一个或一组数据以及处理这些数据的方法和过程的集合。
面向对象的程序设计完全不同于传统的面向过程程序设计,它大大地降低了软件开发的难度,使编程就像搭积木一样简单,是当今电脑编程的一股势不可挡的潮流。
28VGA: 28是指彩色显示器上的黄光网点间距(点距),点距越小的显示器,图像就越细腻、越好,这是因为彩色屏幕上的每个像点都是由一组红、绿、蓝光汇聚而成的,由于在技术上三束光还不能100%地汇聚在一点上,因此会产生一种黄光网点的间隔,这种间隔越小,屏幕上显示的图像越清晰。

计算机

电脑图片(19张)人类的生产活动和社会活动产生了极其重要的影响,并以强大的生命力飞速发展。它的应用领域从最初的军事科研应用扩展到目前社会的各个领域,已形成规模巨大的计算机产业,带动了全球范围的技术进步,由此引发了深刻的社会变革。计算机已遍及学校、企事业单位,进入寻常百姓家,成为信息社会中必不可少的工具。它是人类进入信息时代的重要标志。 计算机是由早期的电动计算器发展而来的。1946年,世界上出现了第一台电子数字计算机“ENIAC”,用于计算弹道。是由美国宾夕法尼亚大学莫尔电工学院制造的。1956年,晶体管电子计算机诞生了,这是第二代电子计算机。只要几个大一点的柜子就可将它容下,运算速度也大大地提高了。1959年出现的是第三代集成电路计算机。最初的计算机由约翰·冯·诺依曼发明(那时电脑的计算能力相当于现在的计算器),有三间库房那么大,后逐步发展。 1946年面世的“ENIAC”,它主要是用于计算弹道。是由美国宾夕法尼亚大学莫尔电气工程学院制造的,它的体积庞大,占地面积170多平方米,重量约30吨,消耗近150千瓦的电力。显然,这样的计算机成本很高,使用不便。这个说法被计算机基础教科书上普遍采用,事实上在1973年根据美国最高法院的裁定,最早的电子数字计算机,应该是美国爱荷华州立大学的物理系副教授约翰·阿坦那索夫和其研究生助手克利夫·贝瑞(Clifford E. Berry ,1918-1963)于1939年10月制造的"ABC"(Atanasoff- Berry-Computer)。之所以会有这样的误会,是因为“ENIAC”的研究小组中的一个叫莫克利的人于1941年剽窃了约翰·阿坦那索夫的研究成果,并在1946年时,申请了专利。由于种种原因直到197望大家记住ABC和约翰·阿坦那索夫,希望以后的教科书能够修改这个错误)。后来为了表彰和纪念约翰·阿坦那索夫在计算机领域内作出的伟大贡献,1990年美国前总统布什授予约翰·阿坦那索夫全美最高科技奖项----“国家科技奖”。

关于computer的雅思写作范文

关于computer的雅思写作范文考雅思前夕,我们应该多积累素材和参考范文呀,下面小编给大家分享一些关于computer的雅思写作范文给大家欣赏。
雅思写作范文:Computer and EducationIntroduction shows main ideaComputers are now essential in many areas of life modern banking, retail and information exchange among others. However, this is not true for education. At a simple level some subjects may be better taught using computers, but to explain important concepts a human teacher is still indispensable.Why computers do well, with examplesThere are some subjects in which a computer can be used successfully to teach. Elementary mathematics, elementary language leaning, any area which requires a student to memorize basic facts through repetition is well suited to computer learning. The computer can be programmed to provide an endless number of simple questions, and as the student answers these questions the facts are learned and reinforced.What computers cannot be, with an exampleHowever, in the learning and practice of more complex ideas, the computer is not adequate. A computer can evaluate an answer as right or wrong, but it cannot determine why. It cannot find out why a student is making mistakes, and then re-present important concepts in a different way so the student will understand. It cannot determine at what stage in a mathematics problem the student has made an error, it can only indicate that the final answer is wrong. Tasks involving reasoning cannot be taught by computers, as there are too many variables for a computer to deal with successfully.Conclusion re-states main ideasThus, while computers may be useful as a tool for practicing simple skills, they are not an essential feature of modern education, because they cannot monitor a student’s grasp of concepts, nor evaluate a student’s reasoning. Until further developments in computers are made the human teacher will remain indispensable.雅思写作高分范文:人们不懂电脑的坏处The one who do not know how to use computer become more and more disadvantageous. Show the disadvantages and what action should government take?Computer plays such an important role nowadays that it undeniably becomes the biggest concern of the present-day world as a whole. With the steady growth in the hi-tech, as well as computer, there is a growing tendency that man who does not know how to use the computer will become an illiterate. As far as I am concerned, there are several major disadvantages for these people.In the first place, without computer's help, someone may waste a large amount of precious time to pay attention to complex calculation. It is believed that computer can do almost everything. It was gradually used not only in mathematics, physics, chemistry and astronomy, but in places like library hospital and military army to replace the works of man. Besides, a computer works much faster and more accurately than man. Therefore, one who cannot use the computer always fails to keep up with the development of modern society.In addition, these kinds of people may lose opportunities that make new friends or contact with outside world and new technology. It is very clear that lots of changes have taken placein many aspects of people's lives because of the coming of the computer era. Multi-media and surfing on-line provide people with chances to learn more about the world and up-dated information. Moreover, sending E-mail seems to be the most convenient and efficient way to communicate with families, relatives and best friends. Unfortunately all above will never happen in the life of the layman.In order to let everyone know about the computer skills, government should set forth solutions to eliminate the number of these kinds of illiterates. First and foremost, it is suggested to open more free related training classes, which can encourage people to cultivate the interesting of using computers. What's more, it is stylish to advertise the benefits to learn the computer.All in all, the future for the computer is very promising. We hardly imagine what our world would be like without the computers.雅思写作大作文真题及参考范文:玩电脑对孩子有益?2月16号雅思写作大作文真题Nowadays, children spend too much time watching TV and playing computer games.

计算机

计算机(全称:电子计算机;别称:电脑,英文:Computer)是20世纪最伟大的科学技术发明之一,对人类的生产活动和社会活动产生了极其重要的影响,并以强大的生命力飞速发展。
它的应用领域从最初的军事科研应用扩展到目前社会的各个领域,已形成规模巨大的计算机产业,带动了全球范围的技术进步,由此引发了深刻的社会变革。
计算机已遍及学校、企事业单位,进入寻常百姓家,成为信息社会中必不可少的工具。
它是人类进入信息时代的重要标志。
计算机是由早期的电动计算器发展而来的。
1946年,世界上出现了第一台电子数字计算机“ENIAC”,用于计算弹道。
是由美国宾夕法尼亚大学莫尔电工学院制造的。
1956年,晶体管电子计算机诞生了,这是第二代电子计算机。
只要几个大一点的柜子就可将它容下,运算速度也大大地提高了。
1959年出现的是第三代集成电路计算机。
最初的计算机由约翰·冯·诺依曼发明(那时电脑的计算能力相当于现在的计算器),有三间库房那么大,后逐步发展。
1946年面世的“ENIAC”,它主要是用于计算弹道。
是由美国宾夕法尼亚大学莫尔电气工程学院制造的,它的体积庞大,占地面积170多平方米,重量约30吨,消耗近150千瓦的电力。
显然,这样的计算机成本很高,使用不便。
这个说法被计算机基础教科书上普遍采用,事实上在1973年根据美国最高法院的裁定,最早的电子数字计算机,应该是美国爱荷华州立大学的物理系副教授约翰·阿坦那索夫和其研究生助手克利夫·贝瑞(Clifford E.Berry ,1918-1963)于1939年10月制造的"ABC"(Atanasoff- Berry-Computer)。
之所以会有这样的误会,是因为“ENIAC”的研究小组中的一个叫莫克利的人于1941年剽窃了约翰·阿坦那索夫的研究成果,并在1946年时,申请了专利。
由于种种原因直到1973年这个错误才被(具体情况参阅百度百科----“约翰·阿坦那索夫”词条,希望大家记住ABC和约翰·阿扭转过来。
电脑的英文名用叫做computer

N: I guess. M: What will you use your computer for? N: Mostly just to go online, to use Word, and to play some games. M: And you probably don’t need anything too fancy. N: No, but I want it to look nice and I want it to be small so I can carry it around with me. M: Ok, well, I think I know exactly what you need. Shall we go to the store? N: Yeah, let’s go!

In 1956, he wanted to get this computer to be able to beat him at checkers(西洋跳棋). How can he write a program,come up with every step , to beat himself?
you have seen som in things and it will show you pictures.
actually what it's doing is it's searching the webpage for the text. this is very different from understanding the images.
So we now know that computers can learn, and computers can learn to do things that we sometimes don't know how to do ourselves or maybe can do them better than us.
But computers can't really think, they don't emote, don't understand poetry……
So what
?
I love them !
at last, I want to say these words as my end
The future has come just yet to be popular...

It is possible to find information by using a computer algorithm(算法). Like Taobao J.D. use machine learning to suggest items that you might like to buy. Sometimes ,it is almost creepy,
You should come up
it is said the possible configurations(构造) of the steps is the number of atoms in the universe.
This is

So it needs machine learning to achieve it
this picture showsuter can analyze data collected by camera,with GPS to locate the car's position
If you want to be able to tell the differences between a tree and a pedestrian , that's important for cars.
We don’t know how to write those programs by hand, but with machine learning, this is now possible.
And in fact ,this car has driven over a million miles without any accidents.

It used to be that if you wanted to get a computer to do something new.

like tencent(qq), sometimes will tell you about who your friends might be.and you have no idea how it did it,and this is because it is using the power of machine learning. these algorithms have learned how to do this from get useful information ,this is what machine learning means.
