Serial ATA is the evolution of the ATA interface from a parallel bus to serial connection architecture.

串行ATA是ATA接口的演变，从ATA的并行总线演变成为串行连接的结构。

The paper holds the idea that, parallel bus can;t adapt to high-speed transfers due to self-limitations, and high-speed serial point-to-point bus will substitute for traditional parallel bus; data transfer will not be carried out simply by drive circuit and parallel bus, but by special high-speed serial bus; the traditional mode of single bus loading multi-device is disappearing, and a centralized switch module is replacing the bus function in a mode of one switch module connecting all devices via high-speed point to point serial bus.

文章认为并行总线由于自身缺陷，已经不适合进行高速传输，高速串行点对点连接将代替传统的并行接口；数据交换也不再是简单地通过驱动电路和并行数据线进行，而是通过特殊的串行高速总线连接；传统的在一条总线上同时挂载多个设备的模式正逐渐消亡，总线功能已被一个集中式的交换模块取代，而交换模块和各个设备都是通过高速串行点对点的方式进行连接。

Maybe daily to see the printer that you are printing a parallel port or USB interface and the computer is connected to; however, the printer prints in addition to the parallel port or USB interface, you might have a serial port, we must not think that this is just a well-display serial interface, because as soon as the printer of the parallel port or USB interface experience a breakdown in normal use, the serial port can make their own role, help printer to serial communication fashion emergency printing.

或者我们常日见到的打印机，都是堵住打印并口或USB接口与计算机拆开的；不过也有的一些打印机除了具有打印并口或USB接口之外，还不定具有一个串口，我们万万必给以为这个串口不光是个部署而已，因为一旦打印机的并口或USB接口碰到障碍不克不及变态搁置时，该串口不离能阐发自己应有的功用，帮忙打印机以串行通讯的方法来达不败济急打印。

The design of the modern electronic device, except for must has multiple functions, but it also trend to achieve slightness, thinness, shortness and smallness in outer appearance. In order to seek such a trend, the components disposed in the electronic device must be reduced in volume correspondingly, and the connectors used therein also must be reduced in volume without exception. For example, the USB connector has developed a mini USB connector, and the digital video signal transmission interface evolves from a digital video interface to a high definition multi-media interface having a smaller volume and a faster transmission speed.

现代电子产品的设计除了要功能多样外，在外观上的趋势是追求轻、薄、短、小，为了追求这样的趋势，电子产品内的各个零件也必须跟着将体积缩小，其所使用的电连接器当然也不例外，如通用串行连接埠推出迷你版的通用串行连接端口，而数字影音讯号的传输接口也由数字视觉接口推演到体积较小，传输速度更快的高速高解析多媒体接口。
