一、计算机2000年问题的由来2000年问题与使用日期的计算机系统有关。在早期的计算机系统中,由于存储器价格昂贵,人们为了节省存储空间,一般都用两位数表示年份,而假定世纪数为19。为了保持应用系统的连续性,这种方法被一直沿用下来。到了九十年代,人们开始发现用两位数表示年份埋下的隐患,计算机在处理跨越2000年的日期问题时,计算、比较、排序或者从一个系统传送给另外一个系统时,以两位数表示年份会导致错误或者重大事故,甚至会使系统崩溃。例如,1995年人们已经发现五年期存款的到期年份是00年,到期日小于开户日,系统拒绝接受或
First, the origin of the year 2000 problem of computers is related to the computer system of the date of use. In the early days of computer systems, due to the high cost of memory, people generally use a two-digit year to save storage space, assuming that the number of century is 19. In order to maintain the continuity of the application system, this method has been used. In the 1990s, people began to find hidden dangers buried in the year with two digits. The computer calculates, compares, sorts, or transfers from one system to another when dealing with dates that span 2000 years. Representing the year will result in errors or major accidents, or even cause the system to crash. For example, in 1995, people had discovered that the maturity date of a five-year deposit was 00 years and the expiry date was less than the account opening date. The system refused to accept or
