It does not support random or direct access. We can not directly access the blocks of a file. A block k of a file can be accessed by traversing k blocks sequentially (sequential access ) from the starting block of the file via block pointers. Pointers required in the linked allocation incur some extra overhead. consumer reports teeth whitening products

When a file is created, the operating system searches for a series of free blocks that are large enough to store the file, and it links them together using pointers.

NettetEach file in a linked allocation is a linked list of disk blocks. A pointer to the file’s first and, optionally, end block is present in the directory. For instance, a file of five blocks beginning at block 4 may go on to block 7, then block 16, then block 10, and then block 27.
