摘　　要：计算机2000年问题在硬件上是由于：系统时间中四位年份是由BIOS（BasicInput—OutputSystem）将RTC（RealTimeClock）所记年份的后两位与CMOS所记年份的前两位结合而成，当RTC由99变为100时，不能正常进位，只能保留后两位，再与CMOS结合形成时间错误所致；在软件上：操作系统和应用程序的时间来源有2000年问题，其本身又不能正确处理所引起．也有些应用程序本身用两位记年或某些操作的默认值与易引发2000年问题的时间点相同所致．对策主要有：硬件方面，通过修改AUTOEXEC．BAT、升级BIOS、更换主板等方法解决；软件方面，自编软件用高版本无2000年问题的相应开发软件重新修改编译，购买的软件要请销售商协助解决．In hardware, the Y2K problem of the computer is caused by the system time composed of the RTC (Real Time Clock) time and the CMOS time. When the dynamic RIT turns to 100 from 99, it noly can saye tow bits behind andcan not carry normally, so the error time is formed. In software, because the time source from the system is error and the system and the apply program themselves can not deal with it correctly, and the apply program itself use two bits to record the year or it's some operation defacdt numbers are equal to the time, so the appry program can cause the Y2K problem easily. The major countermeasure for the Y2K problem is: in hardware, we can deal with it by modifing the file autoexec. bat or upgrading the BIOS or exchamging the main board lin software, software established by yourself yoa can remodity and compile again by using the high version software. to software boaght you can ask the seler for help.
