第三章:现代模块化的诞生—IBM/360电脑的设计革命1复杂性灾难与电脑设计的困境世界上第一台计算机是1944年问世的。它是由18000个真空管组成,足足装了一屋子。虽然,从那以后,计算机及其程序和使用模式等等方面,均以惊人的速度向前发展。但是,从那时起,直到1965年之前的这20多年时间里,计算机都是整机制造的。每开发一款新计算机,都是为了具备某些新的功能,以满足用户新的、特殊的需求。所以,每开发一款新计算机时,指令集、外围设备、应用软件等都需要从头做起。虽然新机型也会采纳和吸收老机型的一些
The third chapter: the birth of modern modular - IBM / 360 computer design revolution 1 complex disaster and the dilemma of computer design The world’s first computer was published in 1944. It is composed of 18,000 vacuum tubes, fully fitted with a house. Although, then, computers, their programs and usage patterns have evolved at an alarming rate. However, since 20 years before 1965, the computers were machine-built. Each development of a new computer, are to have some new features to meet the new, special needs of users. So every time a new computer is developed, the instruction set, peripherals, applications, etc. need to be started from scratch. Although the new models will adopt and absorb some of the old models
