18、technology?Lesson1譯文什么是電腦？由于當(dāng)今科技發(fā)展迅速，幾乎所有的人都對(duì)電腦很熟悉。它已經(jīng)成為人們生活的重要一部分。人人都對(duì)它著迷。現(xiàn)在讓我們看看什么是電腦。它能在指令的存儲(chǔ)程序命令下快速準(zhǔn)確地存儲(chǔ)、處理數(shù)據(jù)，并輸出結(jié)果。它不僅能處理字母、字符和數(shù)字，還能處理聲音、圖像和其他類型的信息。人們能用電腦以一種便捷而又愉快的方式處理日常事務(wù)和許多枯燥的數(shù)字。電腦是人類的朋友，而且也是人們很有用的工具。歷史上第一臺(tái)電腦于1946年被命名為ENIAC（埃尼阿克）。它非常大而且很昂貴。老百姓可買不起。后來(lái)，由于人類智慧的貢獻(xiàn)，電腦越來(lái)越小而且越來(lái)越便宜。現(xiàn)在即使像你我這樣的普通人也能買得起今天市面上電腦種類應(yīng)有盡有。日常生活中人們用電腦學(xué)習(xí)、工作或娛樂。典型的電腦看起來(lái)像是個(gè)電視機(jī)，我們稱之為桌上型電腦。在人們的辦公桌，家里或是網(wǎng)吧都能見到這種電腦，這種電腦通常是個(gè)
