By definition, what is a file?

• Is a piece of hardware in a computer system

• Are logical units of information, created and managed by processes in the operating system

• Is a program that automatically backs up data

• Is an information storage device

Which of the following techniques can be used to minimize backup time and storage space requirements?

• Full backup; used every time to ensure complete restoration

• Incremental backup; only backs up changed data since the last backup

• Manual backup; selectively backs up files chosen by the user

• Direct copy; makes a direct copy of all files without any optimization

Of the three common file structures, which one allows maximum flexibility by storing data as an unstructured sequence of bytes?

• Tree structure

• Record sequence

• An unstructured sequence of bytes

What type of media is the CD-ROM file system designed for?

• Rewritable media

• Write-once media

• Magnetic tape

• Flash memory

What solution integrates multiple file systems into an orderly structure on a computer?

• NTFS

• FAT32

• Virtual File System

• FAT16

In a multi-user computer network where users share a common file server, what can each user have?

• A private root directory for their own hierarchy

• Only one subdirectory in the root directory

• No permission to create additional subdirectories

• Permission to create up to 5 directories only

Rock Ridge Extensions allow CD-ROMs to be read on which operating systems?

• Windows

• macOS

• UNIX

• DOS

When a process creates a file, what happens to the file when the process terminates?

• The file is deleted immediately

• The file continues to exist and can be accessed by other processes using its name

• The file can only be accessed by the process that created it

• The file is automatically backed up

Why is organizing files in a hierarchical directory system more efficient than placing all files in a single directory?

• Because it reduces the time to search for files

• Because it limits the number of files a user can create

• Because it prevents users from creating subdirectories

• Because it is unrelated to file organization

What function does a directory have in an operating system?

• It is a way of organizing files

• It only contains files and no subdirectories

• It is a normal file with no special management by the operating system

• It cannot contain more than 10 files
