State two advantages of storing files using the techniques of linked list allocation using index. Advantages Of Storing Files The main idea behind allocation is effective utilization of file space and fast access of the files. There are three types of allocation: contiguous allocation linked allocation indexed allocation Method of Storing File Contiguous allocation: this scheme used in early systems, allocation using first fit and a need for compaction. Advantage: Simple – only starting location (block #) and length (number of blocks) are required . Advantage is its ease of direct access because every part of the file is stored in the same compact area. Disadvantage: Difficulty in finding space for a new file , Wasteful of space , Suffer from the problem of external fragmentation Contiguous allocation Link- List Noncontigous Allocation:
