In the days of mainframe computers , networks were simply the wires that co ected the dumb terminals to the big box in the basement 在大型计算机时代，网络不过是把哑终端连到地下室里的大盒子上的电线而已。

A shared portal from a local network into a larger information resource such as a large packet - switched information network or a mainframe computer 从一局部网到更大的信息源（例如大型包交换信息网或计算机主机）的一种共享入口。
Continuing up the size scale , the mainframe computer is one that may offer a faster processing speed and a greater storage capacity than a typical mini 相应于尺寸大小，大型机则比典型的小型机提供了更快的处理速度和更大的存储容量。
Continuing up the size scale , the mainframe computer is one that may offer a faster processing speed and a greater storage capacity than a typical mini 随著规模的增加，形成了大型计算机，它比一般的小型计算机有更快的处理速度和更大的存储容量。
Extending the internet all the way down to an individual lightbulb requires recognizing the similarities , and differences , between a bulb and the mainframe computers for which the internet was originally developed 网际网路一开始是为了电脑主机才发展出来，想把网际网路一路扩展到个别的灯泡，就必须找出灯泡与电脑主机之间的异同。
These include the lease - like revenues from licences relating to its mainframe computers and its pioneering “ multi - core ” semiconductors , which feature in ( among other things ) the three leading video - games consoles 这其中包括网络主机相关的租金性的授权使用费以及它行业领先的“多核”半导体技术，这种芯片被用在三大最热门的电视游戏主机上。
During the last two decades , parallel processing and parallel optimization techniques have been developed to take full advantage of computing resources from different sources , either on a mainframe computer or on network of workstations 一些典型的组合优化问题已被证明属于np完全问题，对这些问题的求解，除构造近似算法求解外，也迫切的需要提高计算能力。
The conventional mainframe computers transfer their computing tasks and data processing to distributed network computing environment . the kind of transfer can improve the computing capability of workstation and reduce cost . and at the same time job management system can provide a whole solution about how to use the distributed and heterogeneous computer network to shape the consistent network - computing environment 传统大型计算机的客户都纷纷将自己的计算业务和数据处理转到分布式网络计算环境之中，这种转向无疑增强了工作站的计算能力，降低了成本，同时作业管理系统又解决了如何使分布和异构计算机网络形成协调一致的网络计算环境问题。
