1.Computer Organization
A Computer is a programming,electronic device that accepts input,performs operations or processing on the data,and outputs and stores the results.
Because it is programmable,the instructions_called the program_tell the computer what to do.
The relationships between these four main computer operations (input,processing,output,and storage) are shown in Figure 1-1.
The corresponding devices to perform these tasks are input devices, processing,devices,output devices,and storage devices.

计算机组织计算机是一种编程、电子设备，它接受输入、对数据进行操作或处理，并输出和存储结果。
Because it is programmable,the instructions_called the program_tell the computer what to do.
因为它是可编程的，instructions_called program_tell电脑该做什么。
The relationships between these four main computer operations (input,processing,output,and storage) are shown in Figure 1-1.
这四种主要计算机操作（输入、处理、输出和存储）之间的关系如图1-1所示。
The corresponding devices to perform these tasks are input devices, processing,devices,output devices,and storage devices.
执行这些任务的相应设备是输入设备、处理设备、输出设备和存储设备。

1、 计算机的组成
计算机是一种可编程的电子设备，它接收输入、完成对数据的运算或处理，并输出和存储结果。因为它是可编程的，这些被称为程序的指令告诉计算机去做什么。计算机的这4种主要操作（输入、处理、输出和存储）之间的关系如图1-1所示。
完成这些任务的相应设备是输入设备、处理器、输出设备和存储器。
