Defragmentation
Defragmentation is the rearrangement and collection of files and data
distributed on the hard drive.
A fragmentation in data carriers comes about from fragmented recording of
data in the form of data blocks. The reason for this is the construction of hard
drives, where constant writing takes space away and deleting creates new
space. This leads to eventual distribution of free data blocks all over the hard
drive. When saving a new file, it is separated into fragments and distributed
over the still free memory blocks.
Dialog
A dialog opens in a new window and lets the user interact with the program.
This means that the dialog can present information to the user and/or expects
to receive input from the user.
A dialog can contain various user elements which can be manipulated by a
simple mouse click. Keyboard entries are also possible.
Disc types
The disc types determines the format and medium (CD, DVD, Blu-ray disc,
etc.) to which the current project will be burned.
Double-layer
DVDs can consist of one or two storage layers, and both of these can be
written to. Video DVDs increase the capacity up to 4.5 or 8.5 GB.
During the write and read process, each layer can be accessed without
damaging data on the other layer. One of the biggest challenges of
development of this medium was making normal DVD players able to playback
these discs.
Drag & drop
Enables files and objects to be moved freely between various applications (or
within an application) by dragging the object and letting it drop using the
mouse cursor.
