D.
NTFS
Explanation:
External Serial Advanced Technology Attachment (eSATA) is an external Interface and provides hot swappable hard disk drive solution. It is an external interface for Serial Advanced Technology Attachment (SATA) technology. It is designed to support hot-plugging. Hence, it allows users to connect a hard disk drive while the computer is running. eSATA has data transfer rates three times more than USB 2. 0 and FireWire 400. Unlike USB and FireWire interfaces, eSATA requires its own power connector. eSATA supports a maximum data cable length of two meters. Answer D is incorrect. NTFS is a file system that is used in Windows 7. It is capable of recovering from some disk-related errors automatically. It has improved support for larger hard disks. In NTFS, a user can use permissions and encryption to restrict access to specific files to approved users. Answer
A is incorrect. The Encrypting File System (EFS) is a feature of Windows that permits a user to store information on a hard disk in an encrypted format that is obtained by encryption. Encryption is the process of encoding data for preventing unauthorized access during transmission. Answer
B is incorrect. FAT is a file system supported by Windows NT. The FAT file system is characterized by the file allocation table (FAT). This is a table that resides at the very “top” of the volume. To protect the volume, two copies of FAT are kept in case one becomes damaged. In addition, the FAT tables and the root directory must be stored in a fixed location so that the system’s boot files can be correctly located.
