Explain contiguous allocation, Operating System

Assignment Help:

Contiguous allocation

The contiguous-allocation method needs each file to occupy a set of contiguous blocks of the disk. Disk addresses explain a linear ordering on the disk. Therefore the number of disks seeds needed for accessing contiguously allocated files is minimal. The IBM VM/CMS operating system uses contiguous allocation because it gives such good performance.
