Unit3computers知识点
Unit3computers知识点Unit3 Computers 知识点在我们的日常生活和工作中，计算机（Computers）已经成为了不可或缺的一部分。
接下来，让我们一起深入了解一下关于计算机的一些重要知识点。
一、计算机的发展历程计算机的发展可以追溯到上世纪中叶。
早期的计算机体积庞大、运算速度慢，且功能有限。
例如，第一代计算机使用真空管作为主要组件，它们不仅体积巨大，而且耗能高、发热量大。
随着技术的进步，晶体管取代了真空管，使得计算机变得更小、更可靠、运算速度更快，这便是第二代计算机。
第三代计算机采用了集成电路，进一步减小了计算机的体积，提高了性能。
而到了第四代，超大规模集成电路的出现使得计算机能够走进千家万户，成为人们工作和生活的得力助手。
如今，计算机技术仍在不断发展，朝着更小的体积、更强的性能和更智能化的方向迈进。
二、计算机的组成部分计算机主要由硬件（Hardware）和软件（Software）两大部分组成。
硬件方面，包括中央处理器（CPU），它是计算机的“大脑”，负责执行各种计算和控制任务；内存（Memory），用于暂时存储正在运行的程序和数据；硬盘（Hard Disk），用于长期存储大量的数据和程序；显示器（Monitor），用于显示图像和信息；键盘（Keyboard）和鼠标（Mouse），作为输入设备，用于向计算机输入指令和数据；还有主板（Motherboard）、电源（Power Supply）等其他组件。
软件则分为系统软件（System Software）和应用软件（Application Software）。
系统软件如操作系统（Operating System），如Windows、Mac OS 和 Linux 等，负责管理计算机的硬件资源和提供基本的服务。
应用软件则是为了满足用户特定需求而开发的，如办公软件（Word、Excel 等）、图像处理软件（Photoshop 等）、游戏软件等。

Now computers are becoming smaller and better.Some computers are tiny. You may be unaware of them. There is probably one inside your TV or washing machine. You depend on computers more than you realize. What can we do with computers?We can use computers to calculate. They can calculate at a faster speed than we can and almost never give wrong answers. We can also type and draw things with them. Inaddition, computers can do important jobs like operating railways and flying planes and spaceships.Is a computer cleverer than me?The answer is “No”. Your brain can produce new ideas but computers cannot. However, one day computers may be able to a better job than human beings. For example,they may be better than doctors at doing their job.What will happen to us if computers can do all our jobs? Will we have nothing to do?Computers may change our lives, but will they make them better?越小越好在20世纪40年代，第一台计算机比汽车大。
