What does a Computer Look Like?

To most of computer beginners, a personal computer is made up of three parts from appearance. They are as follows:

● display

● keyboard

● system unit

How can we recognize each part of them? The one that looks like a TV set is the display, it is usually the most obvious part. The keyboard is full of buttons, with which we can input data or program into the computer. The left part is the system unit. It is like a simple box. In the box, there are many important components, which can’t be seen.

Most of the computer beginners may think the display is the most important part. They are wrong. Each part is important for the computer to run smoothly. In price, the system unit is usually the most expensive part.

Besides, there is a mouse by the display. It is a little like a mouse. If you want to play music, a stereo set is usually necessary. The modem is usually needed when you want to get on the Internet. If you want to print something on pieces of paper, you must have a printer.

That is all for simple introduction. If you want to know more about the knowledge of computer, you should spend more time learning the left passages in this book.

參考譯文

對于大多數計算機初學者來說，一臺個人計算機從外觀上主要由3個部件構成。它們如下：

● 顯示器

● 鍵盤

● 主機

我們怎么樣來認識各個部分呢？像電視機的那部分就是顯示器，它通常是最明顯的部分。鍵盤上布滿了按鍵，我們可以通過它向計算機中輸入數據和程序。剩下的部分就是主機。它像一個簡單的盒子，在那里面有很多重要元件，這些通常都看不見。

大多數的計算機初學者都會以為顯示器是最重要的部分。其實他們錯了。每一個部分都對計算機的平穩運行有重要的作用。在價格方面，主機通常是最昂貴的部分。

除了這些，顯示器的旁邊還有一個鼠標，它有點像一只老鼠。假如你要播放音樂的話，必須有一個立體聲設備。要上網通常就得有一個“貓”（調制解調器）。而要把東西打印到紙上的話，就必須有一臺打印機。

簡單的介紹就到這里。要想了解更多的關于計算機的知識，你應該花費更多的時間去學習本書中剩下的文章。

Whenever new information is entered, it must 1 somewhere in the computer’s 2 . Later, the CPU must also be 3 to get this information from memory. This is where RAM is needed. The CPU can 4 write to and read from RAM. RAM is called Random Access Memory 5 the CPU can do directly to any memory location in it. The CPU does not have to look 6 all of RAM to find the spot it needs. But RAM only 7 the data temporarily. As soon as you switch the computer 8 , all that information disappears from the RAM. When you switch the computer on again, the RAM is 9 , and ready 10 a new program and new data.
