11. List and briefly define three file allocation methods? Contiguous allocation: a single contiguous set of blocks is allocated to a file at the time of file creation. Chained allocation: allocation is on an individual block basis.Each block contains a pointer to the next block in the chain...
The main advantage in this type of access is that both direct and sequential access of files is possible with the help of this method.File Allocation Methods in Operating System Free Space Management in Operating System Related Tutorials

Our software keeps applications responsive with advanced allocation strategies and by avoiding logical fragmentation. This alleviates major challenges with intensive workloads. Plus, high read/write throughput and low CPU usage ensure highly responsive systems. Extend flash memory lifetime Put the brakes ...
FAT is by far the most simplistic of the file systems supported by Windows NT. The FAT file system is characterized by the file allocation table (FAT), which is really a table that resides at the very "top" of the volume. To protect the volume, two copies of the FAT are kept in ca...

File fragmentation occurs when a file's data is scattered across non-contiguous locations on the storage medium. In a hierarchical file system, the operating system's file system driver is responsible for managing file allocation and defragmentation. When a file is modified or resized, the file ...
