Linux uses the paging unit more than it does the segmentation unit 在linux中,分页单元的使用多于分段单元。
We get these offsets by breaking the linear addresses we receive as an output from segmentation unit 我们通过进入作为分段单元输出的线性地址,再划分该地址来获得偏移量。
Segmented unit is represented as - segment : offset model can also be represented as - segment identifier : offset 分段单元可以表示成- >段:偏移量模型也也可表示成- >段标识符:偏移量
The paging unit gets in the linear address as an output of segmentation unit which it then further divides into the following fields 分页单元进入作为分段单元输出结果的线性字段,然后进一步将其划分成以下3个字段:
If it is higher than that , one striping unit needs more than one i o to be issued so that it may de - parallel disk i os in large disk arrays 如果大于该尺寸,一个分段单元就需要不止一次地发出i / o ,以便它可以在大型磁盘阵列中近似地并行化磁盘i / o 。
