1.SX 和 DX 有什么不同?在计算机广告中,能看到386和486计算机以 SX或 DX 等型号标出,并且 SX 相对便宜些。两者的区别是:386和486都是32位处理器,386DX 使用32位总线,而386SX 使用16位总线。386SX 在内部数据传输性能上比386DX 要差一些。整体上看,16MHz386D X在执行同样程序时比386SX 要快一些。386DX 和 SX 使用相同的指令集。在486中,DX 和 SX 都使用32位总线,但是486DX 带有数字协处理器,486SX 则没有。2.什么是冷启动和热启动?有何不同?冷启动为加电开机的启动方式。用户打开系统电
1. What is the difference between SX and DX? In computer ads, you can see the 386 and 486 computers are labeled with SX or DX models, and SX is relatively cheaper. The difference between the two is: Both the 386 and 486 are 32-bit processors, the 386DX uses a 32-bit bus, and the 386SX uses a 16-bit bus. The 386SX is worse than the 386DX in internal data transfer performance. Overall, the 16MHz386D X is faster than the 386SX in executing the same program. 386DX and SX use the same instruction set. In the 486, both the DX and the SX use a 32-bit bus, but the 486DX has a digital coprocessor and the 486SX does not. 2. What is the cold start and hot start? What is the difference? Cold start to power-on boot mode. The user opens the system power
