What is a compressed file?
a file consisting of more than one fragment
a file containing more than two identical blocks
a file containing fragments stored on disk in compressed form
a file containing zeros which are not actually stored on the disk

content
size
data and time of file creation
access rights

What is fragmentation?
when a file is stored in several non-contiguous fragments
when two files have identical fragments

cluster
sector
stripe

How is a record storing file metadata and pointers to file content called in Linux?
group descriptor
directory
short form directory
inode
MFT record
indirect block table
What is a minimum unit of disk space a filesystem operates with?
chunk

sector
cluster
How does deduplication work?
a filesystem compresses data before writing it to the disk
a filesystem monitors that exactly one copy of each file metadata block is stored
a filesystem monitors that no more than two copies of each data block is stored
a filesystem monitors that exactly one copy of each data block is stored
