由于AI技术的提高，机器人学发展迅速，总有一天传统计算机和机器人会结合起来，那么未来计算机之间的差异可能比现在的笔记本和台式机还要大。家用计算机可能以机器人或电子宠物的形式出现在我们的生活中，这样计算机将不再是一个静止的机器了，还能参与到我们的生活中来。
Official business computer may develop into two parts of official business robot and personal portable terminal station.The personnels of office work and assign the order through the portable terminal station，robot prepare materials and deal with daily affairs according to orders，which need not people go on and intervene.
而办公计算机也可能演变成办公机器人和个人便携终端两部分，办公室的人员通过便携终端进行工作和下达指令，机器人根据指令准备资料和处理日常事务，而无需人们进行干预，到那个时候，秘书这个职业也许就会出现就业危机了。

Primary Components of a Microcomputer
微型计算机的主要组成部分
There are many types of microcomputers.Here，we will use an IBM Personal Computer （PC）to illustrate the primary components of a microcomputer.Other brands and models of microcomputers exhibit difference in appearance and operations.An IBM PC is shown in the figure.Its primary hardware components are the main frame，the monitor，the keyboard，and many peripherals such as the disk drive，hard disk，printer，and mouse，all of which are hardwired to the main frame.The main frame is the heart of a microcomputer system.It contains the Central Processing Unit （CPU），a chip that controls the major operations of the computer and the main memory.
微型计算机种类繁多。在这里，我们用IBM个人计算机（PC）来解释微型计算机的主要组成部分。其他品牌和型号的微机在外貌和操作上各有不同。一台IBM PC计算机如图所示：它的主要硬件成分是主机、监视器、键盘以及许多与主机相连的外围设备，如磁盘驱动器、硬盘、打印机、鼠标。主机是微机系统的核心，它包括中央处理单元（CPU）和主存，CPU是一块控制计算机主要操作的芯片。
CPU
中央处理单元
CPU is the abbreviation of Central Processing Unit，which is the heart of a computer like the head of a family.Once the power of a computer is turned on，all the behaviors are under the control of CPU.CPU is in an iron box together with other devices such as disk drives，a main memory and a switching power supply etc.In Chinese，the iron box is conventionally called the mainframe.On the back of the mainframe box，there are various ports，with which CPU may be linked with input and output devices.
CPU是中央处理单元的英文缩写。它是计算机的心脏，好比一家之主一样。计算机一旦通电运行，则所有的行为都要在它的控制之下运行。CPU同其他设备如磁盘驱动器、内存和开关稳压电源等被装在一个铁箱子中。在中文里，这个箱子被习惯地称为主机。在主机箱的背后，有各种端口，用来沟通CPU 和其他输入输出设备的联系。
Memory
内存
Primary memory is known as random access memory （RAM）and simple named memory.It is the storage area within the computer that holds programs and data during processing.Memory is only temporary storage area；when processing is complete，memory is cleared.The user needs to load or enter data and programs into the computer memory when using any application on the computer.
主存储器又称为随机存取存储器，简称内存。它是计算机在处理过程中存储程序和数据的区域。内存只是一个临时的存储区域，处理完成后内存就被清空了。用户在使用应用程序时需将数据和程序调入计算机内存。
Different computers have different amounts of memory space，referred to as memory size，ranging from 32，64megabytes to 128megabytes.Today，the memories of some microcomputers even can be expandable to hundreds of megabytes.
不同的计算机具有不同的内存空间，内存空间是指内存的大小，从32兆、64兆到128兆不等。目前有些微机的内存甚至可以扩充到几百兆。
Keyboard and Mouse
键盘和鼠标
A keyboard is a requisite hardware device of a computer.It is an input device most in use，and a dialogue tool between a man and a computer.We can input data needed to be processed or preserved by a computer via a keyboard.
键盘是计算机的一个必要的硬件设备，也是最常用的一种输入设备，是人与计算机的对话工具。我们可以通过键盘把数据、资料等需要计算机处理或保存的信息送入计算机。
A typical includes a group of standard keys set in the center of the keyboard，many function keys and several additional keys.Function and additional keys have different roles in different software.
一个典型的键盘包括一组位于键盘中间的标准键、许多功能键和一些附加键。功能键和附加键在不同的软件中有不同的作用。
Another popular input device is mouse.The mouse is a small，handheld object that is pushed around a desktop to move the cursor on the screen or to select choices from menus displayed on the screen.A mouse is essentially a pointing device that allows the user to do many operations more quickly than he could with the keyboard alone.
另一种常用的输入设备是鼠标。鼠标是一个可以用手在桌面上推动的小东西，通过它可以在屏幕上移动光标或者选中菜单上的某项功能。鼠标是一个必要的外部设备，它可以使用户以比仅使用键盘快得多的速度完成许多操作。
Monitor
显示器
The monitor is an essential output device of a microcomputer.Monitors，also known as video display terminals （VDTs），resemble television screens，and may be either monochrome or color.A monochrome monitor displays only one color on the screen.It is possible white or more eyepleasing green.While color monitors usually offer a wide selection of display colors.
显示器是微机必需的输出设备。显示器类似于电视屏幕，也被称为视频显示终端（VDTs），有单色显示器和彩色显示器。单色显示器屏幕上仅显示一种颜色，这可能是白色或是一种更悦目的绿色。彩色显示器通常提供许多种可供选择的颜色。
Printer
打印机
The printer is the most commonly used output device after the monitor.Printers can create a permanent paper copy of results generated by the program being run on the computer.These printouts are sometimes referred to as hard copy.Printers can also generate listings of programs and graphic images.Three types of printers are available：wire printers，ink jet printers and laser printers.
打印机是除显示器外最常用的输出设备。打印机可以将程序运行的结果打印出来，从而成为永久的纸拷贝。这种打印输出有时也被称为硬拷贝。打印机也可以打印程序列表和图形图片。有三种类型的打印机：针式打印机、喷墨打印机和激光打印机。
To Know Mouse More，to Use Mouse Better了解鼠标，用好鼠标
The Invention of Mouse
鼠标的发明
Mouse was invented by Douglas Engelbart who worked in the Standford Research Institute International （SRI）in 1964，for a time，he always thought how to operate the computer easier，how to instead of inputting the fussy injunction with the keyboard，afterward，he was considered as the mouse father.
鼠标是1964年由在斯坦福研究所（SRI）工作的Douglas Engelbart发明的，他很早就在考虑如何使电脑的操作更加简便，用什么手段来取代由键盘输入的繁琐指令，他别称为“鼠标之父”。
