Term used to describe three periods that are together (...). In English, the ellipsis is often used as an indication to show any omitted word or other text. You'll often see an ellipsis in file names and commands on a computer to indicate the full filename or command is not being displayed. For example, as seen in the picture, a folder could be named "Computer Hope" but displayed as "Compute..." because the file name column is not wide enough to display the full file name.
