CIS 166 week 3 homework

1. File systems manage disk files with a scheme called block allocation. Logical blocks are divided into other data structures, including:
Sections, Rows and tuples
Sectors, Heads and Tracks
Ports, Sectors and sockets
Tracks, Rings and Clusters

2. File allocation tables are used to
Allocate certain portions of a disk drive for the use of specific software applications.
Allocate certain portions of a disk drive for the use of specific users.
Track the location of data stored on the disk and facilitate storing and retrieving data from the disk.
Allocate different disk drives in a hardware system to different file systems.

3. A technique for managing hard disks that enables the installation of multiple file systems on a single physical drive or that lets you configure multiple logical drives is called
Disk partitioning
Disk allocation
Disk formatting
None of the above

4. A DOS/Windows file system can support up to ______ primary disk partitions.
1 4 6 24 48

5. One DOS/Windows extended partition can support multiple what?
Televisions
Logical Drives
Active Partitions
MBR

6. In a DOS/Windows system, physical and logical disk drives are designated by what special characters?
Letter followed by a colon C:
Number followed by a period 1.
Letter in quotes "C"
Number in quotes "1"

7. A DOS file system reserves the first two drive designations for what kind of storage device?
CDRoms
Hard drives
Zip drives
Floppy drives

8. The file system underneath the graphical Win95a OS is very different from the all command-line driven MS-DOS 7.
True
False

9. If you create filenames in Windows (on FAT16 or FAT32) that contain more than eight characters, you won't be able to see them or access them from a DOS command line.
True
False

10. For years computer character data was represented in ASCII format, which stands for:
Americans Should Check Information Incognito
American Standardization Interconnect Information
American Standard Code for Information Interchange
All Students Can Invent Ideas

11. A newer text standard called Unicode is now used by many operating systems. What's the main diff between ASCII and Unicode?
Number of characters supported
Number of supporting actors
Unicode takes less storage space
Support of long file names.

12. Newer operating systems support Long filenames. These LFNs take up lots of space because::
It must be low-level formatted.
They still store the 8.3 name plus the long name
Newer harddrives must be formatted in stages
That's the way it goes.

13. With later versions of Win95, Microsoft introduced a new file system called FAT32. Although there are drawbacks, some positives of FAT32 are:
It can handle more partitions.
It has a smaller, more efficient FAT
It supports larger hard drives than FAT16.
Security enhancements.

14. Win95 and other OSs include disk compression utilities that can provide up to twice as much storage on existing hard drives. Some disadvantages to using disk compression.
It slows performance
It requires at least two physical hard drives
It is less secure than uncompressed volumes
It only works on drives larger than 2 gig.

15. Key benefits of NTFS over FAT32 are:
It works with DOS and Win3x.
It allows Mac systems access to Windows machines.
Support of USB hard drives and CDRoms.
Security and larger drives.

16. The WinNT system that tracks directory entries is known as:
Master Boot Record (MBR)
Master File Record (MFR)
Master File Table (MFT)
File Table Master (FTM)

17. The UNIX file system uses a file system concept called:
Information node (inode)
UNIX nodes (unode)
Directory List Notation (DLN)
None of the above

18. The UNIX file system can cause multiple directory entries to point to the same physical file
True             False

19. A special link in UNIX permits directory pointers across partitions. This link is called a _________ link
hard link
symbolic link
software link
partition link
