Hit
From DigitalJargonBuster
A request for a file. A hit is the sending of a single file whether an HTML file, an image, an audio file, or other file type. Since a single web page request can bring with it a number of individual files, the number of hits from a site is a not a good indication of its actual use (number of visitors). It does have meaning for the website space provider, however, as an indicator of traffic flow.
