questions with 100% correct
answers(100% accuracy)
creating and deleting files in various file systems, - answer FAT: when a
file is deleted it isn't actually removed from the drive. The FAT is just
updated to reflect that those clusters are no longer in use. if new info is
saved it can now overwrite info in these clusters. ---------NTFS: similar to
FAT but clusters are first marked as deleted, thus "moved" to the Recycle
bin. filename is marked with a special character in MFT to indicate the file
is deleted to the computer.
fragmented file - answer These files become "fragmented" meaning they
consist of fragments of data.
swamp file - answer used to augment the RAM.
File Allocation Table, - answer Used to store cluster/file information in
FAT12, FAT16, and FAT32. Information included in the File allocation Table
include: The cluster number of the next cluster for this file is recorded, if
the cluster is the end of a chain, then it has a special end of cluster chain
(EOC) entry, Bad clusters have a special entry, Reserved clusters have a
special entry, open or available clusters are also marked.
exFAT, - answer It is a proprietary file system designed for flash media and
is often dubbed FAT64. exFAT boasts a file size limit of 16 EiB (1 exbibyte =
260 bytes = 1,152,921,504,606,846,976 bytes). There are four major areas
or regions of exFAT:
The main boot region
The backup boot region
The FAT region (normally only FAT1 is found unless TFAT is configured and
then FAT2 will be found)
The data region
, Linux file system and its data structure, - answer Uses ext file system
(most recent version is ext4 many still use ext 3 though; Files stored in
contiguous blocks; size of blocks depends on the parameters used in the
command to create that partition (can be 1024, 2048, or 4096 bytes)
consistency checking, - answer involves scanning a disk's logical structure
and ensuring that it is consistent with its specification.
zero-knowledge analysis, - answer A method for file system repair in which
few assumptions are made about the state of the file system.
partition, - answer
partition table, - answer A 64-byte data structure that provides basic
information for a computers OS about the division of the hard drive into
primary partition.
directory, - answer
directory entry, - answer
sector, corrupted sector, - answer
clusters, cluster allocation and values, - answer
RAM and File slack, - answer
volatile data, - answer Data that is easily lost: examples of volatile data
are swap file, state of network connections, state of running processes.
volume boot record, - answer The first sector of a partition. The volume
boot sector, also called the volume boot record (VBR), is located at the
