“兼容”一词,我们太熟悉了。 平心而论,“兼容”在电脑发展的前期起到过极其重要的作用,可以说:没有“兼容”就没有今天辉煌的电脑业。但也应承认,正是由于“兼容”,也为电脑业埋下了祸种,导致在DOS操作系统版本升级时总是摆脱不了“常规内存”的限制,“扩展内存”的管理;在CPU芯片的换代中总是放不下对8080汇编语言的依恋;就连计算机基本原理也因“兼容”而一直都在沿用冯.诺依曼结构模式。 然而今天,从Windows32到Windows95,又到Windows98,视窗系统是从16位到准32位,再到全32位,人们好象正在为淘汰旧制,建立新规则作准备。难道在新的计算机发展时期,计算机硬软件的某些“兼容”性能就没有存在的必要吗? 众所周知,DOS系统曾有力地推动过个人计算机的普及,但也确实阻碍了 个人计算机的 The word “compatible” is too familiar to us. To be fair, “compatibility” has played an extremely important role in the early days of computer development. It can be said that without “compatibility”, there will be no brilliant computer industry today. But it should also be acknowledged that it is precisely because of “compatibility” that it has also caused misfortunes for the computer industry. As a result, when the DOS operating system version is upgraded, it cannot always get rid of the limitation of “conventional memory” and the management of “extended memory”; In the replacement of the chip, the attachment to the 8080 assembly language is always indispensable; even the basic principle of the computer has been using the von Neumann structure model for “compatibility”. However, today, from Windows 32 to Windows 95, to Windows 98, the Windows system is from 16-bit to 32-bit, to 32-bit, and people seem to be preparing for the elimination of the old system and establishing new rules. Isn’t it necessary to have certain “compatibility” features of computer hardware and software during the new computer development period? As we all know, DOS systems have vigorously promoted the popularity of personal computers, but they have also hindered the development of personal computers.
