In theatre, a monologue is presented by a single character, most often to express their mental thoughts aloud, though sometimes also to directly address another character or the audience. Monologues are common across the range of dramatic media (plays, films, etc.) as well as in non-dramatic media such as poetry. Monologues share much in common with several other literary devices including soliloquies, apostrophes, and aside. There are, however, distinctions between each of these devices.
Similar Literary Devices 
Monologues are similar to soliloquies, apostrophes, and asides. Nevertheless, meaningful differences exist among them. For example, a monologue is distinct from a soliloquy because the latter involves a character relating his or her thoughts and feelings to him/herself and to the audience without addressing any of the other characters. A monologue is the thoughts of a person spoken out loud. Monologues are also distinct from apostrophes, wherein the speaker or writer addresses an imaginary person, inanimate object, or idea. Asides differ from each of these not only in terms of length (asides being shorter) but also in that asides aren't heard by other characters even in situations where they logically should be (i.e. two characters engaging in a dialogue interrupted by one of them delivering an aside).
In ancient Greek theatre, the origin of western drama, the conventional three actor rule was preceded by a two actor rule, which was itself preceded by a convention in which only a single actor would appear on stage, accompanied by the chorus. The origin of the monologue as a dramatic device, therefore, is not rooted in dialogue. It is, instead, the other way around; dialogue evolved from monologue.
Ancient Roman theatre featured monologues extensively, more often than either Ancient Greek theatre or modern theatre. One of the key purposes of these monologues was to indicate the passage of significant amounts of time (that would be tedious to actually play out in real time) within scenes. This type of monologue is referred to as a linking monologue. Other monologue types included "entrance monologues" and exit monologues. In each of these cases a primary function is indicating the passage of time.
From Renaissance theatre onward, monologues generally focused on characters using the extended speech to pursue their dramatic need. Postmodern theatre, on the other hand, often embraces the performative aspects of the monologue, even to the point of challenging the boundary between character portrayal (e.g. acting) and autobiographical speeches.
Types of Monologues 
Interior monologues involve a character externalizing their thoughts so that the audience can witness experiences that would otherwise be mostly internal. In contrast, a dramatic monologue involves one character speaking to another character. Monologues can also be divided along the lines of active and narrative monologues. In an active monologue a character is using their speech to achieve a clear goal. Narrative monologues simply involve a character telling a story and can often be identified by the fact that they are in the past tense.
Macbeth's monologue after he learns that Lady Macbeth has killed herself:
"She should have died hereafter; There would have been a time for such a word : To-morrow, and to-morrow, and to-morrow, Creeps in this petty pace from day to day To the last syllable of recorded time, And all our yesterdays have lighted fools The way to dusty death. Out, out, brief candle! Life's but a walking shadow, a poor player That struts and frets his hour upon the stage And then is heard no more: it is a tale Told by an idiot, full of sound and fury, Signifying nothing."
