Understanding NTFS: File Systems and the Role of Partition Tables in CSCI 1412

This document explores key concepts related to NTFS (New Technology File System) and partition tables as covered in CSCI 1412. It discusses essential characteristics of NTFS, such as its 64-bit addressing and the maximum file name length. Additionally, it addresses why the size of a file may be less than the allocated space on disk. The role of the partition table in the primary boot sector is examined, alongside basic programming outputs. This resource is designed for students to enhance their understanding of file systems and their operations.

  2. Q 1 • Which of the following statements about NTFS is NOT true? • NTFS uses 64 bit addressing. • Supports names up to 255 characters long • Supports paths of up to 32767 bytes • NTFS uses a duplicated FAT32 system • NTFS uses journaling CSCI1412-HW-4

  3. Q2 The size of a file may be less than the space it is allocated on the disk. This is because: • Space is allowed for the file to grow. • Space is required for security information. • Space is allocated in a whole number of clusters. • Space is required for pointing to the next file in the sequence. • Space remains allocated after the file shrinks. CSCI1412-HW-4

  4. Q3 • What is the role of the partition table in the primary boot sector? • To allow the disk to contain different logical disks. • To ensure that if one partition is damaged another may be used. • To map the allocation of areas to data and applications. • To allow different users access to different files. • To indicate damaged parts of the disk. CSCI1412-HW-4
