The term dot in computing refers to a full stop or period, often seperating a file name from an extension, or different parts of an I.P. address or DNS name (e.g. www.wikipedia.org)

In punctuation, the term dot is usually reserved for the middle dot ·‬, or to the glyphs 'combining dot above' ̇ and 'combining dot below' ̣ which may be combined with some letters of the extended Latin alphabets in use in Eastern European languages.

Example characters: ċ‬/Ċ‬ from Maltese and Irish Gaelic (old orthography), ė/Ė from Lithuanian, ġ/Ġ from Maltese and Irish Gaelic (old orthography), ŀ‬/Ŀ from Catalan, ż/Ż‬ from Polish, etc..

The dot above the lowercase i and j is not seen as a dot, but rather as part of the character, and the double dots above several Latin letters such as ä, ë etc. are not dots either, but are Umlauts or diaeresis.
