『貳』 用英語解釋什麼是計算機網路70字
A computer network or data network is a telecommunications network which allows computers to exchange data. In computer networks, networked computing devices exchange data with each other using a data link. The connections between nodes are established using either cable media or wireless media. The best-known computer network is the Internet.
Network computer devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as personal computers, phones, servers as well as networking hardware.
Two such devices can be said to be networked together when one device
is able to exchange information with the other device, whether or not
they have a direct connection to each other.
Computer networks differ in the transmission medium used to carry their signals, the communications protocols to organize network traffic, the network's size, topology and organizational intent.
Computer networks support an enormous number of applications such as access to the World Wide Web, video, digital audio, shared use of application and storage servers, printers, and fax machines, and use of email and instant messaging applications as well as many others. In most cases, application-specific communications protocols are layered (i.e. carried as payload) over other more general communications protocols.

『肆』 急求計算機網路方面的中英文對照
計算機網路-區域網(中英文對照)[1]
http://www.ecity.cn 作者:IT英語 來源:學賽網 2008年3月13日 發表評論 進入社區
Local area data networks,normally referred to simply as local area networks or LANs,are used to interconnect distributed communities of computer-based DTEs located within a single building or localized group of buildings.For example,a LAN may be used to interconnect workstations distributed around offices within a single building or a group of buildings such as a university campus.Alternatively,it may be used to interconnect computer-based equipment distributed around a factory or hospital complex[1].Since all the equipment is located within a single establishment,however,LANs are normally installed and maintained by the organization.Hence they are also referred to as private data networks.
The main difference between a communication path established using a LAN and a connection made through a public data network is that a LAN normally offers much higher data transmission rates because of the relatively short physical separations involved[2].In the context of the ISO Reference Model for OSI,however,this difference manifests itself only at the lower network dependent layers.In many instances the higher protocol layers in the reference model are the same for both types of network.
Before describing the structure and operation of the different types of LAN,it is perhaps helpful to first identify some of the selection issues that must be considered.A summary of some of the these issues is given in Fig. 14-5.It should be stressed that this is only a summary;there are also many possible links between the tips of the branches associated with the figure[3].
1.Topology
Most wide area networks,such as the PSTN,use a mesh(sometimes referred to as a network)topology.With LANs,however,the limited physical separation of the subscriber DTEs allows simpler topologies to be used.The four topologies in common use are star,bus,ring and hub.
The most widespread topology for LANs designed to function as data communication subnetworks for the interconnection of local computer-based equipment is the hub topology, which is a variation of the bus and ring[4].This is shown in Fig. 14-6,sometimes it is called hub/tree topology.
2.Transmission media
Twisted pair,coaxial cable and optical fiber are the three main types of transmission medium used for LANs.
3.Medium access control methods
Two techniques have been adopted for use of the medium access control in the LANs.They are carrier-sense-multiple-access with collision detection(CSMA/CD),for bus network topologies,and control token,for use with either bus or ring networks[5].
CSMA / CD is used to control multiple-access networks.Each on the network「listens」 before attempting to send a message,waiting for the「traffic」to clear[6].If two stations try to send their messages at exactly the same time,a「collision」is detected,an both stations are required to「step back」and try later.
Control token is another way of controlling access to a shared transmission medium that is by the use of a control(pertnission)token.This token is passed from one DTE to another according to a defined set of rules understood and adhered to by all DTEs connected to the medium.A DTE may only transmit a frame when it is in possession of the token and,after it has transmined the frame,it passes the token on to allow another DTE to access the tranamission medium.

局域數據網一般簡稱為區域網,用於在一幢樓內或局限在樓群范圍內把分散的基於計算機數據終端設備互連在一起。例如,一個區域網可以把一幢樓里或像大學校園內各個樓里的各個辦公室的工作站連在一起。另外,區域網也可以把分布在工廠或醫院建築群中的計算機設備連在一起。由於所有這些設備都是一個單位的,因此區域網一般也由這個單位負責安裝和維護。於是這類區域網也叫做專用數據網。
用區域網方式建立的通信線路和通過公用數據網連接的線路兩者的主要區別在於:因為區域網連接的設備之間相對來說距離較近,因而數據傳輸速率高得多。但是在ISO的OSI參考模型中,這種區別只在較低的與網路相關的幾層比較明顯。而很多實例表明,在該參考模型高層協議中,這兩種網路是沒有區別的。
在敘述幾種不同類型的區域網的結構和工作之前先認識一下必須考慮的有關問題可能是很有幫助的。圖14-5概括了其中的某些問題。應該強調的是,這僅僅是一個概括,因為圖中各分支之間還可能有很多鏈路。
1.拓撲結構
大多數廣域網,如公共電話交換網(PSTN)就使用網狀(有時稱為網路)拓撲結構。而區域網,由於用戶數據終端設備相距很近,可採用簡單的拓撲結構。常用的有星形、匯流排、環形和集線器等4種拓撲結構。
應用最廣的、用於本地計算機設備互連以進行數據通信的區域網拓撲結構是集線器拓撲結構。這種拓撲結構是匯流排和環形拓撲結構的變種。圖14-6展示了為這種拓撲結構,有時也稱為集線器/樹形拓撲結構。
2.傳輸媒體
雙絞線、同軸電纜和光纖是區域網採用的3種主要傳輸媒體。
3.媒體訪問控制方法
區域網中採用了兩種媒體訪問控制技術。它們是用於匯流排網路拓撲結構的帶沖突檢測的載波偵聽多路存取(CSMACD)和既可用於匯流排又可用於環形網路的令牌控制技術。
CSMA/ CD用來控制多路存取網路網路上的每個站點在試圖發送信息前先「偵聽」,等待通路空閑。如果兩個站點在同一時刻要發送信息,將會檢測到沖突,這兩個站點必須各自「後退」一步,以後再重試。
令牌控制是另一種用令牌去控制訪問共享傳輸媒體的方法。該令牌按所有連入媒體的DTE都知道並遵守的一套確定的規則從一個DTE傳向另一個DTE。當某一DTE掌握這一令牌時,它才能傳送一幀數據,而在傳送完該幀之後,要將令牌釋放,以便其他DTE訪問該傳輸媒體。

In modern sociey, people who is handicaped in using computer and accessing network are classified as "blinds" naturally. The advantages of captioned facility is significant, the world move much faster than before because of the information exchange and speedy processing of data. You can guess how much business can grow if a spreadsheet need to be calculated using three days instead of one second nowaday, I should say in majority that computers and networking bring much convenience to human life. But there are still dark side of the world. I also observe children that cannot do simple calculation by mind, they have to rely on calculators, a simple form of computer, similar things happen all around us and when time goes by, we are weak in mind manipulation yet also weak in physical because we spent all time around the computer. What a world we are in to say hello to a friend next door by send him email ?
