前言七十年代是硬件的时代,这样说毫不过份。由奇妙的硅所开创的第三代计算机,随着 IC 技术的进展而发展很快,特别是在微型机和小型机领域尤为显著。七十年代,大型机和小型机普遍有两极分化的趋势。集成电路技术的发展促使价格性能比大大提高,可以说,它导致了一埸所谓计算机价格的革命。相形之下,从1960年以来软件技术可以说进展非常迟缓。从这个意义上说,七十年代是硬件的时代,面临八十年代可望软件有所改革,深感时代要求,咄咄逼人。
Preface Seventies is the era of hardware, so to speak not too much. The third generation of computers, pioneered by fantastic silicon, has developed rapidly with advances in IC technology, especially in the area of microcomputers and minicomputers. In the 1970s, mainframes and minicomputers were generally polarized. The development of integrated circuit technology has led to the price performance ratio greatly improved, it can be said that it led to a revolution called the so-called computer prices. By contrast, software technology can be very slow since 1960. In this sense, the seventies is an era of hardware. In the face of the reforms expected of software in the 1980s, we are deeply impressed by the demands of the times and are overbearing.
