摘要

多用户微型计算机系统是个好主意吗?它们往往是60年代和70年代分时主机错误的重新发明。为什么不给每个用户一个真正的微?这个论点将我们引向多处理器系统或网络。但是UNIX是一个有趣的系统,因为它本质上是多编程的,而且如果多编程操作正确,系统本质上就是多用户的。这是一个原则的例子,如果你使事情一般化,你经常会得到意想不到的好处。UNIX本身也有利于文件和其他资源的共享。其他系统往往使公共共享变得困难。UNIX发展为服务于协作用户的小型社区,因此为小型部门提供的“超级”UNIX应该工作得很好(并且确实如此)。当然,UNIX也被用于更大(更少协作!)的环境中,并取得了相当大的成功(但并非没有一些系统维护)。

Microcomputer operating systems panel: UNIX
Are multi-user microcomputer systems a good idea? They tend to be reinventions of the timesharing mainframe mistakes of the 60's and 70's. Why not give each user a real micro? This argument leads one either to multiprocessor systems, or to networking. But UNIX is an interesting system, since it's inherently multi-programmed, and because multi-programming if done correctly makes your system inherently multi-user. This is a case of the principle that if you make things general, you often get unexpected benefits. UNIX also inherently facilitates sharing of files and other resources. Other systems tend to make communal sharing difficult. UNIX evolved to serve a small community of cooperating users, hence a “supermicro” UNIX for a small department should work well (and does). UNIX has also, of course, been used in much larger (and less cooperative!) environments with considerable success (but not without some system maintenance).
