“Get up, boy, it is time to go to school.”
“I dislike having get up early. I can take an on-linelesson at anytime I like.”
It is a completely ordinary dialogue occurring inmodern life. Yes, it is the computer, whose ever-accelerated updating brings about tremendouschanges in our school lives. A typical application is Computer Assisted Instruction (CAI),which aids teacher to impart knowledge to student more efficiently by it’s multimediacharacters. However, a vigorous debate over the issue whether or not teacher are by nomeans important in pedagogy field has intrigued the public. In my submission, the computercan be great help of teacher but they can never replace or surpass the position of teacher. Iwill offer the following reasons.
Firstly, CAI are designed and programmed by human instructor. They only condense parts ofteacher’s experience and intelligence. Moreover, being a successful instructor requires not justthese factors but a wealth of experience and interpret new experiences using that information.The computer after all are man-made machine.
Secondly, the progress of instruction is complicated and complex, and the educationalachievement of CAI is limited. Some sorts of course, such as basic educational course, are not necessarily to be expressed by the computer to reach productiveeffect.
Finally, communications and interactions with teacher and computer are quite different. Thelatter is too impersonal, which ruins the pleasure of emotional exchanges. Sometimes gazingat the cold flickering screen is a disinteresting and tiring experience.
Admittedly, though computer may help teacher to provide student with a richer and moreeffective learning environment, yet they can not substitute the position of teacher, not onlytoday, but the future.

In this period of communication,computer has beenused in all kinds of fields widely, and plays aparticular role in our lives. Especially computer hasbecome more and more important in educationalfield, therefore dozens of people considered teacherscould be replaced computers that will go with thecurrent of the times. The above point is certainlywrong; this essay will outline three reasons.
The main reason is that people’s brain better than computer. Firstly, people design all kinds ofcomputer’s programs. Secondly, computer doesn’t have logistic ideation. Computer only candefend on that designer inputted computer’s programs to judge a question’s right or wrong.In other words, computer can’t defend on thinking that computer independently analyzes aquestion’s right or wrong. In case, designer inputted programs that are wrong. Computeroutput the result that also will be wrong. If this kind of problem happened in classroom,students would be infused plenty of wrong information.
Another reason is that computer’s programs designed software of education that could beamended difficultly.If software of education of bugs were found, commonly these of problemscouldn’t be solved in the classroom. The software was amended that means total of programwere corrected, not only parts of program were inserted or amended usually.
Last but not the least reason is computer is mechanical,it couldn’t be suited all kinds ofstudents and different demands. As students’ intellect is different, same of software couldn’tbase on every status of student to set a perfect project.
In conclusion, computers couldn’t instead of the position of teachers in the classroom,however computer is an absolutely good helper for teacher.

下面是读文网小编为大家带来的计算机知识英语阅读:增加内存会使你的电脑变快吗,欢迎大家学习!
Up to a point,adding RAM (Random Access Memory) will normally cause your computer to feel faster on certain types of operations. The reason why RAM is important is because of an operating system component called the virtual memory manager.
When you run a program like a word processor or an internet browser, the microprocessor in your computer pulls the executable file off the hard disk and loads it into RAM. In the case of a big program like Microsoft Word or Excel, the EXE consumes about 5 megabytes. The microprocessor also pulls in a number of shared DLLs (Dynamic Link Libraries) - shared pieces of code used by multiple applications. The DLLs might total 20 or 30 megabytes. Then the microprocessor loads in the data files that you want to look at, which might total several megabytes if you are looking at several documents or browsing a page with a lot of graphics. So a normal application needs between 10 and 30 megabytes of RAM space to run. On my machine at any given time I might have the following applications running:
A word processor
A spreadsheet
A DOS prompt
An email program
A drawing program
3 or 4 browser windows
A Fax program
A Telnet session
Besides all of those applications, the operating system itself is taking up a good bit of space. Those programs together might need 100 to 150 megabytes or RAM, but my computer only has 64 megabytes of RAM installed.
The extra space is created by the virtual memory manager. The VMM looks at RAM and finds sections of RAM that are not currently needed. It puts these sections of RAM in a place called the swap file on the hard disk. For example, even though I have my email program open, I haven't looked at email in the last 45 minutes. So the VMM moves all of the bytes making up the email program's EXE, DLLs and data out to the hard disk. That is called swapping out the program. The next time I click on the email program, the VMM will swap in all of its bytes from the hard disk, and probably in the process swap something else out. Because the hard disk is slow relative to RAM, the act of swapping things in and out causes a noticable delay.
If you have a very small amount of RAM (say 16 megabytes), then the VMM is always swapping things in and out to get anything done. In that case your computer feels like it is crawling. As you add more RAM you get to a point where you only notice the swapping when you load a new program or change windows. If you were to put 256 megabytes of RAM in your computer the VMM would have plenty of room and you would never see it swapping anything. That is as fast as things get. If you added more RAM it would have no effect.
Some applications (things like Photoshop, many compilers, most film editing and animation packages, etc.) needs tons of RAM to do their job. If you run them on a machine with too little RAM, they swap constantly and run very slowly. You can get a huge speed boost by adding enough RAM to eliminate the swapping. Programs like these may run 10 to 50 times faster once they have enough RAM!

下面是读文网小编为大家带来让你的电脑变快的8个实用小技巧,欢迎大家学习!
Is your desktop or laptop computer starting to feel a little poky? Even after just a few months of use, your PC or Mac may start to lose steam thanks to a fragmented hard drive, too many programs running in the background, or even a rogue piece of malware.
开始察觉到你的台式机或笔记本电脑变的有那么点儿不好用了?只用了几个月,你的PC或MAC就失去了它的锐气,“感谢”硬盘驱动器中的某块碎片吧,这可能是因为太多程序同时在后台运行,或者是一个恶意软件在“淘气”。
Nothing will slow your system down like a virus, a Trojan horse, or other types of malware. Plenty of commercial antivirus applications are available for Windows PCs, but Becky recommends trying Microsoft's free Security Essentials suite, which will sweep your system for any unwanted, nefarious software and provide ongoing protection via regular updates. Just visit Microsoft's Security Essentials website, download and install the software, and follow the instructions.
没有任何东西比病毒,特洛伊木马或者其他恶意软件更能减慢你系统速度的了。现在市面上有各式各样的Windows杀毒软件,但是贝奇推荐你试一试微软的免费安全套装,它将扫除你系统中所有不想要的东西和不法软件,并通过提供定期更新来保护系统。只需要访问微软安全网站(译者注:已链接到中文版地址),按照指示下载并安装该软件即可。
Anti-virus packages from the likes of Norton and McAfee are also available for Mac users, but there's an ongoing debate about whether virus protection on the Mac is more trouble than it's worth, given that malicious hackers are far more focused on Windows than they are on Mac OS X systems.
包括“诺顿”和“迈克菲”(译者注:已链接到中文版地址)在内的杀毒软件对于苹果机也很有用,但是有一个正在进行中的关于是否真的值得在苹果机上安装杀毒软件的讨论,因为那些制造恶意程序的黑客们更多集中于Windows系统而不是苹果机使用的Mac系统。

购物是一件很开心的事情,购物[Shopping]意指:购买物品。简单来说就是人们购买各种各样物品的行为或方式,物品包括实物和虚拟物品。对很多人来说,购物是一种休闲活动,可以逛不同的商店选购产品。下面读文网小编为大家带来购物英语口语对话,欢迎大家学习!
ALEX: Can I help you?
SHERRY: Yes, I need to buy a computer for this semester.
I was told it is cheaper to buy computers here.
ALEX: Well, you heard right.
You can get an excellent deal on a new computer here.
We have great discounts for students.
SHERRY: I don‘t know much about computers.
But I know I want a desktop computer with a lot of memory. And I need a printer.
ALEX: Well, first let‘s consider your computer.
Here, for example, is a system I highly recommend--the Power Macintosh G3.
It comes with 64 megabytes of total memory.
SHERRY: Is that a lot? Sixty-four?
ALEX: Yes, it is. It should be enough for any student needs you might have.
What department are you in?
SHERRY: History.
ALEX: Well, so you will mostly be using word processing, for writing papers.
I recommend the Corel Word Perfect program for word processing.
We can talk about software later. Let‘s talk about your hardware first.
We have a special deal on right now.
I should tell you about it, as it only goes until next Tuesday.
If you buy one of these fifteen-inch color monitors with a Power Macintosh G3,
you can actually get 30 percent off the usual sale price.
SHERRY: Thirty percent?
ALEX: Yes.
SHERRY: Wow. That‘s really good.
And you think this is really a good system for a graduate student?
ALEX: Yes. It‘s an excellent system.
SHERRY: Hmm. Hey, wait. This has an Apple on it. Is this an Apple computer?
ALEX: Yes, it‘s a Macintosh. It‘s Apple. Macintosh and Apple are the same thing.
SHERRY: I don‘t want Macintosh. I want PC.
ALEX: I‘m sorry, but our university computer center only sells Macintosh equipment.
SHERRY: What? Are you serious?
ALEX: Yes.
SHERRY: But nobody uses Macintosh!
ALEX: That‘s not true.
Most of the students and professors in the university here use Macintosh.
They find it is better for writing and word-processing,
and that is what students mostly do. May I ask where you‘re from?
SHERRY: Yes, I‘m from Taiwan.
ALEX: Well, I know that in most Asian countries Apple is not very popular.
But here in America, especially in universities and publishing companies,
Apple is very commonly used.
SHERRY: But I need a computer that can handle writing in Chinese.
ALEX: There are several Chinese writing programs you can use with Macintosh.
Chinese is no problem for Apple.
SHERRY: Hmm.
I think I should ask some of my friends for advice before I make a decision.
I‘m sorry.
ALEX: No, don‘t be sorry. It‘s reasonable to ask your friends.
But believe me, most of the students here in the university--
Asian students included--most of them use Apple.
SHERRY: Well, thanks for your advice. I will probably come back later.
ALEX: You‘re very welcome. Here is my card, if you need any help.

内存是计算机中重要的部件之一,它是与CPU进行沟通的桥梁。计算机中所有程序的运行都是在内存中进行的,因此内存的性能对计算机的影响非常大。接下来小编为大家整理内存大就会让电脑变快吗?,希望对你有帮助哦!
Up to a point, adding RAM (Random Access Memory) will normally cause your computer to feel faster on certain types of operations. The reason why RAM is important is because of an operating system component called the virtual memory manager.
When you run a program like a word processor or an internet browser, the microprocessor in your computer pulls the executable file off the hard disk and loads it into RAM. In the case of a big program like Microsoft Word or Excel, the EXE consumes about 5 megabytes. The microprocessor also pulls in a number of shared DLLs (Dynamic Link Libraries) - shared pieces of code used by multiple applications. The DLLs might total 20 or 30 megabytes. Then the microprocessor loads in the data files that you want to look at, which might total several megabytes if you are looking at several documents or browsing a page with a lot of graphics. So a normal application needs between 10 and 30 megabytes of RAM space to run. On my machine at any given time I might have the following applications running:
A word processor
A spreadsheet
A DOS prompt
An email program
A drawing program
3 or 4 browser windows
A Fax program
A Telnet session
Besides all of those applications, the operating system itself is taking up a good bit of space. Those programs together might need 100 to 150 megabytes or RAM, but my computer only has 64 megabytes of RAM installed.
The extra space is created by the virtual memory manager. The VMM looks at RAM and finds sections of RAM that are not currently needed. It puts these sections of RAM in a place called the swap file on the hard disk. For example, even though I have my email program open, I haven't looked at email in the last 45 minutes. So the VMM moves all of the bytes making up the email program's EXE, DLLs and data out to the hard disk. That is called swapping out the program. The next time I click on the email program, the VMM will swap in all of its bytes from the hard disk, and probably in the process swap something else out. Because the hard disk is slow relative to RAM, the act of swapping things in and out causes a noticable delay.
If you have a very small amount of RAM (say 16 megabytes), then the VMM is always swapping things in and out to get anything done. In that case your computer feels like it is crawling. As you add more RAM you get to a point where you only notice the swapping when you load a new program or change windows. If you were to put 256 megabytes of RAM in your computer the VMM would have plenty of room and you would never see it swapping anything. That is as fast as things get. If you added more RAM it would have no effect.
Some applications (things like Photoshop, many compilers, most film editing and animation packages, etc.) needs tons of RAM to do their job. If you run them on a machine with too little RAM, they swap constantly and run very slowly. You can get a huge speed boost by adding enough RAM to eliminate the swapping. Programs like these may run 10 to 50 times faster once they have enough RAM!

许多操作电脑的命令、电脑中的一些重要名词、概念等都来自日常英语词汇,如果英语基础好,对这些命令、名词、概念等稍加分析、记忆就能掌握。接下来小编为大家整理了学好英语有助于学习电脑,希望对你有帮助哦!
许多操作电脑的命令、电脑中的一些重要名词、概念等都来自日常英语词汇,如果英语基础好,对这些命令、名词、概念等稍加分析、记忆就能掌握, 可凭借英语单词的词义来加深对电脑知识的理解。如:DEL(删除文件命令)=Delete(删除),MD(建立子目录命令)=Make Directory(建立目录),CD(改变或进入目录命令)=Change Directory(改变目录),CLS(清除屏幕命令)=Clear Screen(清除屏幕),CHKDSK(检查磁盘状态命令)=Check Disk(检查磁盘),VER(显示版本号命令)=Version(版本)等等。
在电脑中有一些非常重要的、常用的术语、软件名称、略写形式的专有名词,都源于常用英文单词或多个英文单词的首写字母。例如:被称为计算机心脏的CPU(中央处理器)=Central Processing Unit(中央处理单元),DOS=Disk Operating System(磁盘操作系统),PC=Personal Computer(个人电脑),MPC=Multimedia Personal Computer(多媒体个人电脑),VCD=Video Compact Disk(视频压缩光盘),RAM=Random Access Memory(随机存储器,即人们常说的“内存”)。国际标准计算机编码:ASCII=American Standard Code for Information Interchange(美国标准信息交换码)。世界上流行最早、使用人数最多的电脑高级语言——BASIC=Beginner's All-purpose Symbolic Instruction Code(初学者通用符号指令代码)。还有一些必须掌握的基本概念,如电脑存储容量单位:KB=Kilo Byte(千字节),MB=Mega Byte(兆字节),GB=Giga Byte(千兆字节)。K=Kilo——表示“千”。M=Mega——表示“兆;百万”。G=Giga——表示“千兆;十亿”。B=Byte,表示“字节”,是电脑最小存储单位(一个字节可以存储一个英文字母,每两个字节可以存放一个汉字)。
要掌握电脑技术,不但要学好一般日常英语,更重要的是应学好电脑英语。由于电脑里的命令、高级语言的语句等在电脑中均需占一定的空间,从节约和简练的原则出发,为充分发挥其效能,电脑在存储和显示这些信息时,通常尽量采用缩略的形式,使其语句十分简洁,加之专业术语较多,逐渐形成了人们常说的“电脑英语”。如果电脑英语像一般英语那样结构松散,书写完整,就会显得冗长口罗嗦,编写程序或阅读起来就会感到十分困难和诸多不便。尽管有的人学过多年英语,对绝大多数电脑里的英语句子能翻译、能理解,而对有些电脑英语词句就不知其所以然了。在电脑英语中有的语句按照字面意义、按照语法规则或习惯表达法去分析均视为错误,但在电脑英语中则是正确的表达方法。例如:
1、Data record too large(数据记录太大),正常英语应写成The data record is too large.
2、Drive A not prepared(驱动器A没有准备好),应为Drive A is not prepared.
3、Program too big to fit in memory(程序太大,不能装入内存),普通说法是The Program is too big to fit in the memory.
4、Write protect error writting drive A(写信息时驱动器A中软盘处于写保护状态),一般英语表达成Drive A is in the status of writting protect when you are writting data on the floppy disk.
5、General failure reading(writting) drive A(读写驱动器A失败),一般英语应写成There is a general failure in reading(writting) drive A。
上面几个句子如按照字面意义或语法规则去分析,都或多或少有错,但在电脑中这些表达方式却是对的。我们不难发现,学好英语特别是学好电脑英语,不但可以加快掌握电脑知识,做到“既知其然又知其所以然”,而且还可以大大降低学习电脑的难度。

多媒体计算机作为教学媒体的一种,它同样是来存储、传递教育和教学信息的,。接下来小编为大家整理了电脑多媒体技术的介绍,希望对你有帮助哦!
Animation refers to moving graphics images. The movement of somebody giving CPR makes it much easier to learn cardiopulmonary resuscitation, rather than just viewing a static picture. Just as a static graphics image is a powerful form of communication, such is the case with animation. Animation is especially useful for illustrating concepts that involve movement.
Such concepts as playing a guitar or hitting a golf ball are difficult to illustrate using a single photograph, or even a series of photographs, and even more difficult to explain using text. Animation makes it easier to portray these aspects of your multimedia application.
