To answer this question, let's break down the statement and go through each option:
The statement is: "Though in NAS, we have file level data access, file blocks can be accessed by application."
Option A) True - This option is incorrect because in Network Attached Storage (NAS), file blocks cannot be accessed directly by applications. NAS provides file-level access, which means that applications can access files as a whole, but they do not have direct access to individual file blocks.
Option B) False - This option is correct because it accurately states that file blocks cannot be accessed by applications in NAS. Applications can only access files at the file level, not at the block level.
The correct answer is B) False.
