Chained allocation: allocation is on an individual block basis.Each block contains a pointer to the next block in the chain. Indexed allocation: the file allocation table contains a separate one-level index for each file;the index has one entry for each portion allocated to the file. 连续分...
Optimal File Allocation in a Multiple Computer System 来自 Semantic Scholar 喜欢 0 阅读量: 14 作者: WW Chu 摘要: A model is developed for allocating information files required in common by several computers. The model considers storage cost, transmission cost, file lengths, and request rates,...
Space Allocation Files are allocated disk spaces by operating system. Operating systems deploy following three main ways to allocate disk space to files. Contiguous Allocation Linked Allocation Indexed Allocation Contiguous Allocation Each file occupies a contiguous address space on disk. ...

The FAT file system is named for its method of organization, the file allocation table (FAT), which resides at the beginning of the volume. To protect the volume, two copies of the FAT are kept in case one becomes damaged. In addition, the FAT tables and the root directo...
operating system and different disk technology is likely to be encountered at some point. Therefore, 512 bytes per sector was viewed as having a large possibility of not always being a good fit for the allocation. This was accomplished by allowing the cluster to be defined as multiples of the...
