False

A compressed image file can be reconstructed if a lossy compression algorithm is used because the compression process is reversible.

False

A field is a group of related records that can be identified by the user with a name, type, and size.

False

A relative filename is a name that is selected by the File Manager when the file is created.

True

A subdirectory is created when a user opens an account to access the computer system.

False

A volume must contain a single file.

True

Although noncontiguous allocation schemes eliminate external storage fragmentation and the need for compaction, they don't support direct access because there's no easy way to determine the exact location of a specific record.

False

An indexed sequential file does not have overflow areas.

True

Blu-ray discs are available in several formats: read-only (BD-ROM), recordable (BD-R), and rewritable (BD-RE).

True

Direct access storage devices (DASDs) are devices that can directly read or write to an arbitrary place on a disk.

True

Directories are special files that contain listings of filenames and their attributes.

False

Files cannot be converted from sequential to direct or vice versa.

False

In a file directory tree structure, the "leaves" of the tree are subdirectories created by the user.

True

Many systems force users to have their files organized for fixed-length records if the records are to be accessed directly.

True

Sequential record organization is by far the easiest to implement because records are stored and retrieved serially, one after the other.

False

The File Manager responds to the CREATE command by creating a new file.

True

The universal serial bus (USB) controller acts as an interface between the operating system, device drivers, applications, and the devices that are attached via the USB host.

True

To support text compression, data in a fixed-length field that includes a short name followed by many blank characters can be replaced with a variable-length field and a special code to indicate how many blanks were truncated.

False

When a user gives a command to modify the contents of a file, it's actually a command to access folders within the file.

True

When using a contiguous file storage scheme, the File Manager keeps track of empty storage areas by treating them as files.
