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 ?

Smartphones in the Future
Smartphones are very smart,but how about their owners?Are their owners as smart as the phones in the future?We do not know.Some owners are smarter than their phones,while other owners are not as smart as their phones,or less smart than their phones.If the owners are less smart than their phones,their smartphones are a waste of money and time for their owners,since the owners do not know how to use their smartphones.If the owners want to outsmart their smartphones,they have to work hard to become smarter,which not many of them can do.So what can we expect in the future for smartphones?
DONE.

Computer networks
Now every almost have computers, and computer good does have its downside - it depends on how you use. If you want to ask me: I on the computer do what, I can tell you, I will do a lot of things in the computer. May first and have out-of-town relatives chat, then can check information, listening to music, watching movies, paint... My favorite on the computer music and watching movies, because it very relaxing my mood.But the most people used compter to surf the internet.Now Let us know about the computer network
Ⅰ.Introction
Computer networks,the wide spread sharing of information among groups of computers and their users,are a central part of the information age.The popular adoption of the personal computer(PC)
and the local area network (LAN) ring the 1980s has led to the capacity to access information on a distant database;download an application from overseas;send a message to a friend country;and share files with a colleague-all from a personal computer.
The network that allow all this to be done so easily are sophisticated and complex entities.They rely for their effectiveness on many cooperating computers.The design and deployment of the wordwide computer network can be viewed as one of the great technological wonders of recent decades. Nowadays Intemet is very popular all over the world, especially in some big cities. Do you know when the Intemet was first established? Built in 1960s, the Internet was a crude network of a few computers which shared information. If one of the computers broke down, the whole networks would be unable to work, causing continual problems. At first, just the government had access to the Internet, using it for communications among different branches. However, by 1970s the Internet had been used in universities, banks, and hospitals. At the beginning of 1990s computers became affordable for common people and this affordability increased the use of the Internet by people,It is said that each day tens of millions of people log off, making it the most important part of people's life.
Ⅱ.Local Area Network
One of the most dramatic events in computer networking has been the introction and rapid growth of local area network(LAN) as a way to standardize the system of linking computers used in office systems.As the name suggests,this is a means of connecting a number of computing elements together.At the simplest level,a LAN provides no more more than a shared medium (such as a coaxial cable to which all computers and printers are connected) along with a set of rules that govern the access to that medium.The most widely used LAN,Ethernet,used a mechanism called Carrier Sense Multiple Access-Collosion Detect(CSMA-CD).This means that each connected device can only use the cable when it has established that each connected device is using it.If there is contention, the device looking for a connection backs off and tries again later.The Ethernet transfers data at 10M bits/sec,which is fast enough to make the distance between devices insignificant.They appeat to be connected directly to their destination.
There are many different layouts(such as bus ,star,ring,see Figure 6A-2)and a number of different access protocols for LANs.Despire this variety,all LANs share the feature that they are limited in range (typically they cover one building) and are fast enough to make the connecting network invisible to the devices that use it.
In addition to providing shared access,modern LANs can also give users a wide range of sophisticated facilities.Managenment software packages are available to control the way in which devices are configured on the local area network (LAN),how users are administered,and how network resources are controlled.A widely adopted structure o local network is to have a number of servers that are available to a (usuallu much greater) nember of clients.The former,usually powerful computers,provide service such as print control,file sharing,and mail to the latter,which are usually personal computers.
Ⅲ.Routers and brideges
The facilities on most local area network (LAN) are very powerful.Most organizatonns do not wish to have small isolated islands of computing facilities.They usually want to extend facilities over a wider area so that groups can wok wtthout having to be located.Routers and bridges arespecialized devices that allow two or more local area network (LAN) to be connected.The bridges is the more basic device and can only connect local area network (LAN) of the same type.The router is a more intelligent component that can interconnent many different types of computer network.
Many large companies have corporate adta network that are founded on a collection of local area network (LAN) and routers.From the user』s point of view,this arrangement provides them with a physically diverse network that looks like one coherent resource.
Ⅳ.Wide Area Networks
At some point,it becomes impractical to extend a local area network (LAN) any further.Physical limitation sometimes drives this,but more often than not there are more concenient or cheaper ways to extend a computer network.Two major components in most real computer networks are the public telephone and data networks.These provide long-distance links that extend a local area network (LAN) into a wide area network (WAN).Nearly all of the national network operators offer services for the interconnection of computer networks.These services range from simple, low speed data links that work over the public telephone network to sophisticaied high speed data services that are ideally suited to the interconnection of LANs.These high speed data services are usually referred to as broadband connection.It is anticiopated that they will provide the necessary links between LANs that make what is called the information superhighway a reality.

We build computer to solve problems.Early computer solved mathematical and engineering problems,and later computers emphasized information processing for business applications.T-
oday,computers also control machines as diverse as automobile engines,robots,and microwave ovens. A computer system solves a problem from any of these domains by accepting input,processing it,and procing output. Fig. 1-1 illustrates the function of a computer system.
Computer systems consist of hardware and software. Hardware is the physical part of the system. Once designed,hardware is difficult and expensive to change. Software is the set of programs that instruct the hardware and is easier to modify than hardware. Computers are valuable because they are general-purpose machines that can solve many different kinds of problems,as opposed to special-purpose machines that can each solve only one kind of problem. Different problems can be solved with the same hardware by supplying the system with a different set of instructions.that is,with different software.

計算機組成原理
計算機硬體
人們為解決問題而製造計算機。早期的計算機解決的是數學和工程問題,後來計算機著重解決商業應用中的信息處理問題。如今,計算機還用來控制如汽車發動機、機器人和微波爐等各式各樣的機器。計算機系統解決上述這些領域中的任何一個問題都是通過接收輸入、處理問題和生成輸出來實現的。圖1-1說明了計算機系統的功能。
計算機系統由硬體和軟體組成。硬體是系統的物理部分。硬體一旦設計完畢,要修改是困難的,並且花費也大。軟體是指揮硬體的程序集合,比硬體容易修改。計算機之所以有用,是因為它們能解決很多不同類型的問題,是通用的機器。相對而言,每種專用機只能解決一類問題。通過為系統配備不同的指令系統,也就是配備不同的軟體,能用同一硬體去解決不同的問題。
⑹ 簡述按覆蓋范圍劃分計算機網路的分類類型有哪些 英語縮寫分別是什麼
按覆蓋范圍劃分計算機網路可分為三類:區域網、城域網和廣域網。
它們的相應英文縮寫是:LAN、MAN和WAN。
計算機網路是指將地理位置不同的具有獨立功能的多台計算機及其外部設備,通過通信線路連接起來,在網路操作系統,網路管理軟體及網路通信協議的管理和協調下,實現資源共享和信息傳遞的計算機系統。
(6)計算機網路分類英語作文擴展閱讀:
從整體上來說計算機網路就是把分布在不同地理區域的計算機與專門的外部設備用通信線路互聯成一個規模大、功能強的系統,從而使眾多的計算機可以方便地互相傳遞信息,共享硬體、軟體、數據信息等資源。簡單來說,計算機網路就是由通信線路互相連接的許多自主工作的計算機構成的集合體。
計算機網路就是由大量獨立的、但相互連接起來的計算機來共同完成計算機任務;最簡單的計算機網路就只有兩台計算機和連接它們的一條鏈路,即兩個節點和一條鏈路。
