内存调度页  

分页,调页,页式调度 一种虚拟内存操作技术。操作系统把主内存空间划分成若干定长的页，从而简化了操作系统分配与管理主内存的工作，并能提高存储器的存储密度。采用这种方法，可以在有限的存储空间上执行大于实存储空间的作业。

In , paging is one of the schemes by which a computer can store and retrieve data from for use in . In the paging memory-management scheme, the operating system retrieves data from secondary storage in same-size called pages. The main advantage of paging over is that it allows the physical address space of a process to be . Before paging came into use, systems had to fit whole programs into storage , which caused various and problems.

Paging is an important part of implementation in most contemporary general-purpose operating systems, allowing them to use disk storage for data that does not fit into physical (RAM).
