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.

To answer this question, you need to understand the SCSI-1 standard.

SCSI stands for Small Computer System Interface and is a set of standards for connecting and transferring data between computers and peripheral devices. SCSI-1 is the first version of the SCSI standard.

According to the SCSI-1 standard, a maximum of 8 devices can be connected through a SCSI cable. This includes the host adapter (the SCSI controller in the computer) and the peripheral devices (such as hard drives, CD/DVD drives, scanners, etc.).

Therefore, the correct answer is:

Option A) 8 - This option is correct because according to the SCSI-1 standard, a maximum of 8 devices can be connected through a SCSI cable.
