分时系统(time-sharing system):分时系统允许多个用户通过终端同时访问系统,共享CPU时间,操作系统以时间片为单位,轮流为每个终端用户服务,提供了较好的交互性。 批处理系统(Batch Processing System):批处理是指计算机操作员将作业组织成批,提交给操作系统,由操作系统控制它们自动运行。这种采用批处理技术的操作系统称为...

PURPOSE:To ensure an accurate working with an operating device for hierarchy file with no consciousness of the hierarchical structure of a directory by displaying graphically the hierarchical structure of a complicated file system and selecting a desired directory out of the displayed hierarchical ...
这是我自学 MIT6.033 课程的第一部分:Operating Systems 的笔记。 该课程共分为 4 部分:Operating Systems、Networking、Distributed Systems、Security 课程详细介绍可以查阅:https://blog.miigon.net/posts/mit6033-computer-system-design/笔记为学习过程中随笔记录以及思考,未经整理,所以可能会比较零散。
The zone is then installed by the global administrator, who uses the zone administration command zoneadm to install software at the package level into the file system hierarchy established for the zone. The zoneadm command is used to boot the zone. The global administrator can then log in to...
存储器层次结构(memory hierarchy) 容量较大、价格较低 的 慢速存储器,是容量较小、价格较高的 后备快速存储器。 低层 的 访问频率递减。 若字节位于 第二级 存储器,字节首先需要转移到 第一级 存储器中,再由存储器来存取。当 第一级 存储器的 存取次数 所占比例较高时,总平均存取时间 更接近于 第一级...
