总线类型
总线的类型有三种：数据总线、地址总线和控制总线。
每条总线上的通信都是在另一条总线的配合下进行的。
数据总线是用于CPU与存储器、CPU与I/O之间交换数据的信号线，并处理存储在指定位置的数据。
交换的数据包括用于计算的数值、计算结果、外部设备的输入信号和输出到外部设备的信号。
地址总线是用于指定存储器和I/O位置的信号线。
交换数据时，需要指定数据的发送目的地或数据的存储目的地。
地址总线指定此位置。
控制总线是用于指定读取还是写入地址总线指定的位置的信号线。
当控制总线发出“写入”指令时，地址总线上指定的存储器和I/O接收数据总线上发送的数据。
当控制总线发出“读取”指令时，数据被输出到数据总线。
