二、程序语言从上述的章节中我们看到,机器的操作可以通过键盘和光笔来完成。在键盘的操作过程中,只要按下按键,就能启动键盘时序,来完成操作过程,也就是说,键盘的操作是由硬件来完成。光笔的操作是通过顺序交换一系列指令来实现的,即光笔的操作是由软件来完成。 Second, the programming language From the above chapter we can see that the operation of the machine can be completed by the keyboard and light pen. In the operation of the keyboard, just press the button, you can start the keyboard timing to complete the operation process, that is, the keyboard operation is done by the hardware. The operation of the light pen is achieved by the sequential exchange of a series of instructions, ie the operation of the light pen is done by software.
