㈠ 高中生英語演講關於電腦或者網路的(在線等)3分鍾
A computer is a machine that manipulates data according to a set of instructions.
Although mechanical examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century (1940–1945). These were the size of a large room, consuming as much power as several hundred modern personal computers (PCs). Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space. Simple computers are small enough to fit into a wristwatch, and can be powered by a watch battery. Personal computers in their various forms are icons of the Information Age and are what most people think of as "computers". The embedded computers found in many devices from MP3 players to fighter aircraft and from toys to instrial robots are however the most numerous.
The ability to store and execute lists of instructions called programs makes computers extremely versatile, distinguishing them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore computers ranging from a mobile phone to a supercomputer are all able to perform the same computational tasks, given enough time and storage capacity.
Programming languages provide various ways of specifying programs for computers to run. Unlike natural languages, programming languages are designed to permit no ambiguity and to be concise. They are purely written languages and are often difficult to read aloud. They are generally either translated into machine code by a compiler or an assembler before being run, or translated directly at run time by an interpreter. Sometimes programs are executed by a hybrid method of the two techniques. There are thousands of different programming languages—some intended to be general purpose, others useful only for highly specialized applications.
Computers have been used to coordinate information between multiple locations since the 1950s. The U.S. military's SAGE system was the first large-scale example of such a system, which led to a number of special-purpose commercial systems like Sabre.
In the 1970s, computer engineers at research institutions throughout the United States began to link their computers together using telecommunications technology. This effort was funded by ARPA (now DARPA), and the computer network that it proced was called the ARPANET. The technologies that made the Arpanet possible spread and evolved.
In time, the network spread beyond academic and military institutions and became known as the Internet. The emergence of networking involved a redefinition of the nature and boundaries of the computer. Computer operating systems and applications were modified to include the ability to define and access the resources of other computers on the network, such as peripheral devices, stored information, and the like, as extensions of the resources of an indivial computer. Initially these facilities were available primarily to people working in high-tech environments, but in the 1990s the spread of applications like e-mail and the World Wide Web, combined with the development of cheap, fast networking technologies like Ethernet and ADSL saw computer networking become almost ubiquitous. In fact, the number of computers that are networked is growing phenomenally. A very large proportion of personal computers regularly connect to the Internet to communicate and receive information. "Wireless" networking, often utilizing mobile phone networks, has meant networking is becoming increasingly ubiquitous even in mobile computing environments.
The need for computers to work well together and to be able to exchange information has spawned the need for many standards organizations, clubs and societies of both a formal and informal nature.
電腦是一台操縱根據指令集的數據。
雖然電腦機械事例,通過記錄的人類歷史上存在很多,首先開發了電腦在20世紀中期(1940年至45年)。這是一個大房間的大小,功耗一樣,數百現代(PC)的個人電腦。關於集成電路的現代計算機的倍比早期的機器能夠十億百萬美元,占據空間小部分。簡單的電腦足夠小,能夠裝到手錶,並且可以通過手錶電池供電。在各種形式的個人電腦是信息時代的圖標,並且大多數人認為是「電腦」。在嵌入式設備中發現的許多MP3播放器到戰斗機,從玩具到工業機器人的電腦但最多。
能夠存儲並執行指令的列表稱為程序使電腦非常多才多藝,他們的區別計算器。教會-圖靈論題是這種多功能性的數學聲明:任何一個有某些最低限度的能力的電腦上,原則上執行相同的任務,任何其他電腦可以執行的能力。因此,從電腦手機到超級電腦都能夠完成同樣的計算任務,足夠的時間和存儲容量。
編程語言提供了指定的電腦程序運行的各種方法。與自然語言,編程語言的目的是不允許任何含糊和精簡。它們是純粹的語言文字,而且往往難以朗讀。他們一般都翻譯成機器代碼編譯器或匯編程序運行之前,或翻譯,直接在運行時由一名翻譯的時間。有時候程序執行的是兩種方法混合方法。有許多不同的編程語言成千上萬的一些擬通用,其他人只需要高度專業化的應用非常有用。
電腦被用來協調20世紀50年代以來,在多個地點的資料。美國軍方的SAGE系統是第一個大規模實施這些制度,這導致了特殊用途的軍刀等商業系統的數量規模的例子。
在20世紀70年代,在研究機構的電腦工程師在美國開始他們的計算機連接在一起使用電信技術。這一努力是ARPA的資助(現在DARPA)的,以及計算機網路,它被稱為產生了ARPANET。該技術取得了ARPANET可能擴散和演變。
隨著時間的推移,以後的學術和軍事機構網路化,成為稱為電腦互聯網。網路的出現,涉及的性質和計算機邊界的重新定義。計算機操作系統和應用程序進行了修改,包括能夠定義和訪問網路上的資源,如其他計算機外圍設備,存儲的信息,等等,為擴展名的個人電腦上的資源。開始時,這些設施主要是人們可以在高科技環境中工作,但在20世紀90年代申請的蔓延,如電子郵件和萬維網,與發展經濟結合起來,如乙太網和ADSL網路技術的快速看到電腦聯網變得幾乎無處不在。事實上,該是聯網的計算機數量正在飄洋過海。個人電腦的一個非常大的比例,定期連接到互聯網來進行交流和接收信息。 「無線」網路,往往利用行動電話網路,意味著網路正在成為即使在移動計算環境日益普及。
對於電腦需要很好地協同工作,並能夠交換信息促成了許多標准組織,俱樂部和雙方正式和非正式性的社會需要。
