【摘要】 计算机出现的半个世纪的时间里,随着操作系统地不断发展,计算机运行模式经历了巨大的变化。由最初的计算和输入输出在同一台机器上完成到采用批处理技术分离打印和计算,进而采用Spooling技术使I/O操作和计算完全并行。为了使多个作业同时运行,实现多用户共享,在分时系统的基础上实现了虚拟主机,达到了共享资源,降低费用的目的。随着计算机性能的提高,系统能够用一部分资源来处理人-计算机界面,用户界面设计开始引起人们的注意,嵌入式系统开始走入我们的生活。更多还原

【Abstract】 With the constant development of operating system,the running mode of computer has had the enormous change in half a century since the computer appeared.At first,calculation and I/O operation can be done at the same machine,and they are separated only when batch processing is applied.In the later time,the technology of Spooling makes I/O and calculation runs side by side totally.In order to make many jobs run in the same period,and realize the multi-user sharing,the technology of virtual is adopted on the foundation of time sharing to reach the shared resource and reduced expenses.With the improvements of performance,a part of resource can be used to resolve human computer interaction.The design of user’s interface has begun to bring people’s attention,and embedded systems begin to enter into our life.This paper reviews the history of the running mode of computer,and points out the result of the development.更多还原
