Final answer:
True, indexed allocation does support both sequential and direct access to the file, offering a flexible and efficient file allocation method popular in various file systems.
Step-by-step explanation:
The statement that indexed allocation supports both sequential and direct access to the file is true. Indexed allocation is a method of file allocation used in computer file systems. Each file has its own index block which is an array of disk-block addresses.
The advantage of indexed allocation is that it can support direct access without external fragmentation as each index provides a direct pointer to each block, making it efficient for both sequential and direct access. It is indeed one of the most popular forms of file allocation because it provides flexibility and efficient access to files of various sizes and access patterns.
Indexed allocation is a file allocation method in which a file is divided into multiple blocks and an index table is used to keep track of the blocks. Each entry in the index table corresponds to a block in the file. The index table allows for direct access to any block in the file, enabling random or direct access.
Sequential access means reading or writing data in a sequential manner, from the beginning to the end of the file. Direct access, on the other hand, allows for reading or writing data at any location in the file.
So, the statement is true. Indexed allocation supports both sequential and direct access, making it a popular form of file allocation.
