（3）Output Devices
Like input units,output devices are instruments of interpretation and communication between humans and computer systems of all sizes.These devices take out put results from the CPU in machine-coded form and convert them into a form that can be used(a) by people (e.g.a printed and/or displayed report) or (b) as machine input in another procession cycle.
In personal computer systems,display screen and desktop printers are popular output devices.Larger and faster printers,many online workstations,and magnetic tape drives are commonly found in larger systems.

In personal computer systems,display screen and desktop printers are popular output devices.
在个人计算机系统中，显示屏和台式打印机是流行的输出设备。
Larger and faster printers,many online workstations,and magnetic tape drives are commonly found in larger systems.
更大、更快的打印机、许多在线工作站和磁带驱动器通常存在于更大的系统中。
（3） 输出设备
与输入设备类似，输出设备也是人与各类计算机系统之间进行解释和通信的设备。输出设备从CPU中取出机器代码形式的输出结果，然后将其转换成人们可读的形式（例如打印或显示报告）或另一处理周期的机器输入代码。
在个人计算机系统中，常用的输出设备是显示器和台式打印机。比较大型的计算机系统通常要配备更大、更快的打印机、多台在线工作站和磁带机等。
