Unit3computers知识点
Unit3computers知识点一、计算机的发展历程计算机的发展可以追溯到古代，人们使用算盘等工具进行计算。
然而，现代计算机的发展始于 20 世纪。
在20 世纪 40 年代，第一台电子计算机ENIAC 诞生。
它体积巨大，使用了大量的真空管，运算速度相对较慢。
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、更节能。
集成电路的出现进一步推动了计算机的发展，将大量的晶体管集成在一个芯片上。
微处理器的发明使计算机变得更加小巧和强大，个人计算机逐渐普及。
从台式机到笔记本电脑，再到如今的平板电脑和智能手机，计算机的形态不断变化。
二、计算机的组成部分计算机主要由硬件和软件两大部分组成。
硬件包括中央处理器（CPU）、内存、硬盘、显示器、键盘、鼠标等。
CPU 是计算机的核心，负责执行指令和进行计算。
内存用于暂时存储正在运行的程序和数据，而硬盘则用于长期存储大量的信息。
显示器用于显示图像和文字，键盘和鼠标是输入设备，用于向计算机输入指令和数据。
软件分为系统软件和应用软件。
系统软件如操作系统（Windows、Mac OS、Linux 等），负责管理计算机的资源和提供基本的服务。
应用软件则是为了满足用户特定的需求，如办公软件（Word、Excel、PowerPoint）、图像处理软件（Photoshop）、游戏等。
三、计算机的工作原理计算机的工作原理基于二进制。
所有的数据和指令都以 0 和 1 的形式存储和处理。
当我们打开计算机并运行一个程序时，程序和相关的数据被加载到内存中。
CPU 从内存中读取指令，并按照指令进行操作。
例如，计算两个数的加法，CPU 会从内存中获取这两个数，进行加法运算，并将结果存储回内存。
计算机的处理过程遵循着“输入处理输出”的模式。
通过输入设备输入数据，经过 CPU 和其他硬件的处理，最终通过输出设备（如显示器、打印机）输出结果。
四、计算机网络计算机网络使得多台计算机能够相互通信和共享资源。
