Android
Android is the human-like robot. The word "android" comes from the Greek "Andr-" that means "person, man" and "-eides" that means "like, similar". The word droid is the word from the "Star warriors" that was a short form of the android. First the word was got by the French writer Mathias Villiers de l'Isle-Adam who used this word in his work "Tomorrow's Eve" describing the human-like woman Hadaly. Hadaly was speaking with the help of phonograph that was giving the classical quotations to talk. According to another version the word "android" came from the creator of the first mechanical toys Anry Dro.
Very often to make the androids look like people different organic elements are added to them such as the skin. In some science fiction novels androids are described as the electronic and mechanical robots that have the human look. In other novels so called androids are completely organic but are created artificially. There were also a lot of other intermediate notions and definitions.
The word cyborg is very much connected with the notion of androids that is in fact the cybernetic organism. The accent is made on the combination of the biological and electronic and mechanical systems.
Although the human-like robots already exist, the word android didn't leave the science fiction and mass media usage and didn't become the technological term.
The classical stories of Isaac Asimov are about androids. These stories give the rules for the ethics of androids and robots that influenced other authors and investigators a lot in the definition of these terms.
