  1. a server is a computer system that provides services to other computing systems or clients over a network.

  2. because it is small mobile computer/personnal computer. It allow user to just place on the anywhre like on ur leg, table.

  3. use for application, calculation and task.

  4. already no power…how to show ler? check on the power supply wheather have problem or not. especially the cable.if the cable no problem then the power suply maybe have problem.

  5. Internet Explorer, Mozila Firefox, Opera. (u wan wat browser?)

1。电脑的发明家是？？
2。打印机的发明家是？？
3。键盘的排列式是谁，几时和怎样排出来的？
4。color printer 和 laser printer 的分别是什么？
5。laser printer 里有些什么？

1.John W.Mauchly 和J.Presper Eckert
2.Hertz，Zoltan, Kyser 和 Sear
3。是Christopher Latham Sholes在1868年排出来的，最常用的几个字母安置在相反方向，最大限度放慢敲键速度以避免卡键，就是今天键盘的排列方式！
4。分别在于素质，价钱，速度~
5。有墨粉盒，传感器条板及传输器锁盘，卡纸盒。。。

。电脑的发明家是？？
這題就和那天的一樣廣義，你所謂的電腦是指哪個時代的，世界第一台還是開始有完整定義開始？？
1623年德國科學家契克卡德發明世界第一台電腦

2。打印机的发明家是？？
昏~~ 又是這種問題，當然是只有找了
In 1938, Chester Carlson invented a dry printing process called electrophotography commonly called a Xerox, the foundation technology for laser printers to come.

http://inventors.about.com/library/inventors/blcomputer_printers.htm

3。键盘的排列式是谁，几时和怎样排出来的？
我們現在打字鍵盤最上一行的排列是QWERTYUIOP，此排列法稱為QWERTY。當初發明打字機時最直接的想法自然是把二十六個英文字母順序排列，但問題馬上出現，字母柄的起落總是聚在一邊撞作一團。打字機這個偉大的新產品一看便知是可以令人發達的發明，參與此項創業投資的老闆（venture capitalist）實在急不及待要把產品推出市場，逼迫發明者只用了六個月時間（1800年），以亂試（trial-and-error）的方式重新把二十六個英文字母排列，成了一直用到現在的QWERTY排列法。

4。color printer 和 laser printer 的分别是什么？
一般的color printer都是噴墨打印機，噴墨主要是由點組成，每寸範圍内的點越細數量越多畫質越清晰。laser打印機所採用的是鐳射，液晶快門或發光二極體，這比普通使用bright light的複印機還要清晰，而且使用laser打印機列印的顔色都可以防水

5。laser printer 里有些什么？
鐳射，簡狀透鏡， 透鏡，六角反射鏡，馬達，反射鏡，光感鼓。列印過程會先佈電，曝光，顯像，轉像，定像，清潔，除像

1.什么是防火墙〔FireWall〕？
防火墻即是一個控制封包傳送的功能，它具有阻隔或過濾與控制臺的來往連綫，從而達到阻止駭客或不明代碼的入侵，也加強了網絡之間的安全性。Windows操作系統所提供的防火墻一般來説不太好，因爲其只能夠阻隔外來的數據封包而無法達到監控本身對外封包的傳送，市面上比較好且免費的軟体要數Zone Alarm Pro。

2.什么是点对点技术〔peer-to-peer〕？
點對點技術即是讓電腦與電腦間通過一個Server互相連接，這比我們使用搜索器對http搜索要收集資料來的準確，但唯一的缺點就是所連接的點過於少的時候，其封包傳送的速度也會稍慢。

3.FTP服务的Port是多少？
File Transfer Protocol 的 port 預設都是 21， 但有些服務器爲了避開惡意入侵都會換成其他的。

4.黑客是如何入侵个人电脑的？[答案不需要太过复杂，因为答案有很多]
“個人電腦”的入侵方法幾乎都是相同，惡意者會把某些木馬病毒合併于一些文件或圖片中讓其他用戶打開。這樣沒安裝防毒軟体或沒更新病毒檔的電腦就會在暗中運行木馬，這樣一來惡意者就可以通過木馬的主程序控制對方電腦及竊取資料。以上皆為不暴露的情況下入侵，另外所說的暴露在外的就是把自己電腦架設為服務器，這樣的話駭客可以通過操作系統的漏洞或通過一些"軟件"測試系統的漏洞，從而進行暴力式破解或漏洞攻擊進行入侵。

5.什么是代理服务器〔Proxy〕？
代理服務器就是代理網絡用戶去取得網絡信息。一般瀏覽器取得網絡信息後對方再把信息以bit方式傳送回來。代理服務器是介于瀏覽器和Web服務器之間的一台服務器，代理服務器取得瀏覽器所需要的信息並傳囘給瀏覽器。大部分代理服務器都具有緩沖的功能，就好象一個大的Cache，它有很大的存儲空間，它不斷将新取得數據儲存到它本機的存儲器上，如果瀏覽器所請求的數據在它本機的存儲器上已經存在而且是最新的，那麼它就不重新從Web服務器取數據，而直接将存儲器上的數據傳送給用戶的瀏覽器，這樣就能顯著提高瀏覽速度和效率

1.what is server ? what it use ?(hard)
A host computer on a network that holds information (eg, Web sites) and reponds to requests for information from it (eg, links to another Web page). The term server is also used to refer to the software that makes the act of serving information possible. Commerce servers, for example, use software to run the main functions of an e-commerce Web site, such as product display, online ordering, and inventory management.

2.why laptop being named by laptop ?(normal)
~used to put on top of the lap.

3.Normally a computer is used to do what ?(easy)
~input,output,process and store data.

4.(IQ)When a computer show u that it has no power on what happen with it and what should u check? (the answer will be changed depends on ur answer which men it has no a fix answer ,so try to answer it until nothing i can change)(extra hard)
~First, check the plug. Try reseting the plug. Then check the fan, if the fan is not on then should be the power supply failure. Else some other part might goes wrong. Pay attention to beep sound, different beep sound actually tells u something.

5.please list out some of the browser name .(normal)
~FireFox, IE, Netscape, Opera…

  1. who is the inventor of computer?
    ~KONRAD ZUSE

  2. who is the inventor of printers?
    ~Remington-Rand

  3. who design the position of keyboard key and which year it born and how it’s key position being design ?
    ~QWERTY keyboard ,QWERTY design was patented by Christopher Sholes in 1868 and sold to Remington in 1873.

  4. what is the difference between color printer and laser printer ?
    ~color printer nkjet printers consist of nozzles that produce very small ink bubbles that turn into tiny droplets of ink. The dots formed are the size of tiny pixels. Ink-jet printers can print high quality text and graphics.
    A laser printer is a common type of computer printer that produces high quality text and graphics on plain paper. Like photocopiers, laser printers employ a xerographic printing process but differ from analog photocopiers in that the image is produced by the direct scanning of a laser beam across the printer’s photoreceptor.

  5. what does a laser printer have ?
    ~use toner, a black or colored powder

1.什么是防火墙〔FireWall〕？
~A firewall is a hardware or software solution to enforce security policies. In the physical security analogy, a firewall is equivalent to a door lock on a perimeter door or on a door to a room inside of the building - it permits only authorized users such as those with a key or access card to enter. A firewall has built-in filters that can disallow unauthorized or potentially dangerous material from entering the system. It also logs attempted intrusions.

2.什么是点对点技术〔peer-to-peer〕？
~Process whereby computers can trade information between each other directly without the assistance of a third party network.

3.FTP服务的Port是多少？
~port 21

4.黑客是如何入侵个人电脑的？[答案不需要太过复杂，因为答案有很多]
~Hacker can write specific programs to gain access into the computer system.

5.什么是代理服务器〔Proxy〕？
~A firewall mechanism that replaces the IP address of a host on the internal (protected) network with its own IP address for all traffic passing through it. A software agent that acts on behalf of a user, typical proxies accept a connection from a user, make a decision as to whether or not the user or client IP address is permitted to use the proxy, perhaps does additional authentication, and then completes a connection on behalf of the user to a remote destination.

5.什么是代理服务器〔Proxy〕？

1.在电脑中，防火墙是一种装置，它是由软件或硬件设备组合而成，通常处于企业的内部局域网与Internet之间，限制Internet用户对内部网络的访问以及管理内部用户访问外界的权限。换言之，防火墙是一个位于被认为是安全和可信的内部网络与一个被认为是不那么安全和可信的外部网络(通常是Internet)之间的一个封锁工具。防火墙是一种被动的技术，因为它假设了网络边界的存在，它对内部的非法访问难以有效地控制。因此防火墙只适合于相对独立的网络，例如企业内部的局域网络等

2.点对点技术（peer-to-peer， 简称P2P）又称对等互联网络技术，是一种网络新技术，依赖网络中参与者的计算能力和带宽，而不是把依赖都聚集在较少的几台服务器上。P2P网络通常用于通过Ad Hoc连接来连接节点。这类网络可以用于多种用途，各种檔案分享软件已经得到了广泛的使用。P2P技术也被使用在类似VoIP等实时媒体业务的数据通信中。
纯点对点网络没有客户端或服务器的概念，只有平等的同级节点，同时对网络上的其它节点充当客户端和服务器。这种网络设计模型不同于客户端-服务器模型，在客户端-服务器模型中通信通常来往于一个中央服务器。

  1. 21
    4.使用木马病毒，使用系统漏洞，使用windows bug, 用软件突破防火墙。。。
    5。代理服务器是位于用户计算机与 Internet 之间的中间计算机。它既可用于登录 Internet，也可用于拦截对 Web 站点的访问。

  1. a firewall is a type of software which functions in a networked environment to prevent some communications forbidden by the security policy, analogous to the function of firewalls in building construction.

2.A peer-to-peer or P2P computer network is a network that relies primarily on the computing power and bandwidth of the participants in the network rather than concentrating it in a relatively low number of servers. Sharing content files, containing audio, video, data or anything in digital format is very common, and realtime data, such as telephony traffic, is also passed using P2P technology.

  1. 2 type, 20 and 21.

  3. A proxy server is a computer that offers a computer network service to allow clients to make indirect network connections to other network services. A client connects to the proxy server, then requests a connection, file, or other resource available on a different server. The proxy provides the resource either by connecting to the specified server or by serving it from a cache. In some cases, the proxy may alter the client’s request or the server’s response for various purposes.

2.Dual Core Processor 是怎样运作的？（中）
3.RAM 的用途是什么？（中）
4.什么是网际网络？（容）
5.OS 是什么来的，全名叫什么？ ？ （难）

为了不会华语的网友我特别用英文翻译以上的问题。
1.what processor is the famous in nowadays?(easy)

Who answer intel Pentium the is correct already .

2.how dies a dual core processor works?(normal)

dual-core processor consists of two complete execution cores in one physical processor (right), both running at the same frequency. Both cores share the same packaging and the same interface with the chipset/memory(answer from jimson) , 两个核心共用同一条FSB,各个核心有自己的cache memory(answer from retnuoc) A dual-core CPU combines two independent processors and their respective caches and
cache controllers onto a single silicon chip, or integrated circuit. (answer from 如果。。。 )

3.what is the RAM in CPU use for ?(normal)

Random Access Memory , Is type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices. The memory will gone when cpu power off.

4.what is internet? (easy)

The Internet is a network of networks, linking computers to computers sharing the TCP/IP protocols. Each runs software to provide or “serve” information and/or to access and view information. The Internet is the transport vehicle for the information stored in files or documents on another computer. It can be compared to an international communications utility servicing computers. It is sometimes compared to a giant international plumbing system. The Internet itself does not contain information. It is a slight misstatement to say a “document was found on the Internet.” It would be more correct to say it was found through or using the Internet. What it was found in (or on) is one of the computers linked to the Internet.

5.what is OS ?(hard)

Operating System
An operating system (sometimes abbreviated as “OS”) is the program that, after being initially loaded into the computer by a boot program, manages all the other programs in a computer. The other programs are called applications or application programs. The application programs make use of the operating system by making requests for services through a defined application program interface (API). In addition, users can interact directly with the operating system through a user interface such as a command language or a graphical user interface (GUI).
An operating system performs these services for applications:
• In a multitasking operating system where multiple programs can be running at the same time, the operating system determines which applications should run in what order and how much time should be allowed for each application before giving another application a turn.
• It manages the sharing of internal memory among multiple applications.
• It handles input and output to and from attached hardware devices, such as hard disks, printers, and dial-up ports.
• It sends messages to each application or interactive user (or to a system operator) about the status of operation and any errors that may have occurred.
• It can offload the management of what are called batch jobs (for example, printing) so that the initiating application is freed from this work.
• On computers that can provide parallel processing, an operating system can manage how to divide the program so that it runs on more than one processor at a time.
All major computer platforms (hardware and software) require and sometimes include an operating system. Linux, Windows 2000, VMS, OS/400, AIX, and z/OS are all examples of operating systems.

  1. In computer science, a firewall is a piece of hardware and/or software which functions in a networked environment to prevent some communications forbidden by the security policy, analogous to the function of firewalls in building construction. A firewall has the basic task of controlling traffic between different zones of trust. The ultimate goal is to provide controlled connectivity between zones of differing trust levels through the enforcement of a security policy and connectivity model based on the least privilege principle.

  2. A peer-to-peer (or P2P) computer network is a network that relies primarily on the computing power and bandwidth of the participants in the network rather than concentrating it in a relatively low number of servers. P2P networks are typically used for connecting nodes via largely ad hoc connections. A pure peer-to-peer network does not have the notion of clients or servers, but only equal peer nodes that simultaneously function as both "clients" and "servers" to the other nodes on the network.

  3. FTP uses 2 TCP connections (or channels), 1 for control and one for data. The standard control connection is TCP port 21. The default data connection (and extremely rare to see - you can almost forget it exists) is port 20.

  4. A hacker is a person who creates and modifies computer software and computer hardware, including computer programming, administration, and security-related items. The most common tactic that a hacker use to penetrate another PC is by installing a hidden backdoor software (usually is call trojan horse also) to enable him take control over the PC.

  5. A proxy server is a computer that offers a computer network service to allow clients to make indirect network connections to other network services.

1.什么是防火墙〔FireWall〕？
A firewall is either the program or the computer it runs on, usually an Internet
gateway server, that protects the resources of one network from users from other
networks. Typically, an enterprise with an intranet that allows its workers access to the
wider Internet will want a firewall to prevent outsiders from accessing its own private data
resources.

2.什么是点对点技术〔peer-to-peer〕？
A network computing system in which all computers are treated as equals on
the network. Individual computers may share hard drives, CD-ROM drives, and other
storage devices with the other computers on the network.

3.FTP服务的Port是多少？
Port 21

4.黑客是如何入侵个人电脑的？[答案不需要太过复杂，因为答案有很多]
Hackers will use some programs to find a way to get into the system.
Hackers use to attack the machine or network are fairly simple. A hacker scans for
vulnerable systems by using a demon dialer (which will redial a number repeatedly until a
connection is made) or a wardialer (an application that uses a modem to dial thousands of
random phone numbers to find another modem connected to a computer).
Another approach used to target computers with persistent connections, such as DSL or
cable connections, employs a scanner program that sequentially "pings" IP addresses of
networked systems to see if the system is up and running.

5.什么是代理服务器〔Proxy〕？
A server that acts as an intermediary between a workstation user and the
Internet so that the enterprise can ensure security, administrative control, and caching
service. A proxy server is associated with or part of a gateway server that separates the
enterprise network from the outside network and a firewall server that protects the
enterprise network from outside intrusion.
