In [[mathematics]], '''connectedness'''<ref>{{Cite web|url=http://www.dictionary.com/browse/connectedness|title=the definition of connectedness|website=Dictionary.com|access-date=2016-06-15}}</ref> is used to refer to various properties meaning, in some sense, "all one piece". When a mathematical object has such a property, we say it is '''connected'''; otherwise it is '''disconnected'''. When a disconnected object can be split naturally into connected pieces, each piece is usually called a ''component'' (or ''connected component'').
