[[Software]] is necessary for [[user]]s to [[access]] and manipulate digital information stored inside a [[computer]] or on [[storage media]]."<ref>''Id.''</ref> Digital information is not just words and numbers. Anything that can be seen or heard can be [[digitize]]d, so [[database]]s can include music, [[motion picture]]s, or photographs of art works. Some [[database]]s consist primarily of images. Mixed media or [[multimedia]] works are those that package together [[information]] in the form of [[image]]s, [[sound]], and/or [[text]]. The salient aspects of digital information are the following: * '''Reproducible.''' Unlike a physical book or [[photograph]] or [[analog]] [[audio recording]], a digital information object can be [[copied]] infinitely many times, often without losing any [[fidelity]] or [[quality]]. * '''Easily shared.''' Because [[information]] is easily [[copied]], it is also easy to [[distribute]] at low cost. Digital information can be shared more easily than any type of [[analog]] [[information]] in the past. In the physical world, [[broadcasting]] [[information]] to groups has serious costs and hence requires a certain wherewithal and commitment. Technologies such as [[e-mail]] and [[website]]s allow [[broadcasting]] to many people at the touch of a single [[button]]. * '''Flexible.''' A variety of different types of [[information]] can be represented [[digital]]ly: [[image]]s, [[movie]]s, [[text]], [[sound]]. Digital information can even be used to control movement in the physical world through [[digital]]ly-controlled [[actuator]]s. * '''Easily modified.''' Digital representations of [[information]] can be easily [[manipulate]]d. It is trivial to modify an [[image]] — say, changing hair color from blond to red, adding a few notes to a [[musical composition]], or deleting and adding [[text]] to a document. So, for example, a naked body can be affixed to a head of a child, words modified from their original [[intent]] and [[music]] "borrowed" freely, and even [[virtual]] "people" created, all without leaving a visible trace of these [[manipulation]]s. * '''Difficult to intercept.''' Because no physical object is necessarily associated with a digital information object, [[interdiction]] of digital information is much more difficult than [[interdiction]] of a physical object carrying [[information]]. In other words, there is no book, no magazine, no [[photo]] that can be [[intercept]]ed by physical means.
