What’S PC! PC(Personal Computer),顾名思义为个人电脑,但若从电脑外部来看这些组件的话。我们大致上看到的,多为输入与输出的装置,如:输入资料的键盘与鼠标,输出影像的显示器,输出漂亮照片及文件的打印机等,而下图也正是我们一般所见的PC外观,但多年以来,从电脑的外观上,似乎看不出太大的变化,因为真正的变化是暗藏在主机机箱内的元件,如:CPU处理速度的突飞猛进(80286到PentiumⅢ,存储器容量的倍增(1MB到128MB),硬盘空间的增加(20MB到6.4GB)等。
What’s PC! PC (Personal Computer), as the name suggests, is a personal computer, but if you look at these components from outside the computer, We generally see that most of the input and output devices, such as: input data keyboard and mouse, the output image display, a beautiful photo and file output printer, etc., and the following figure is also what we generally see the PC Appearance, but over the years, from the computer’s appearance, it does not seem to see too much change, because the real change is the components hidden in the host chassis, such as: CPU processing speeds by leaps and bounds (80286 to Pentium III, memory capacity doubled (1MB to 128MB), increased hard disk space (20MB to 6.4GB), etc.
