Prior to organized data archiving, researchers wanting to evaluate or replicate a paper would have to request data and methods information from the author.

Pull requests form the foundation of network computing, where many clients request data from centralised servers.

This heuristic algorithm complements a previously-existing algorithm that automatically (but not heuristically) converted requests, based on conditions such as path busy and on request data size.

This led to potential situations where one request could take a device offline for servicing, changing tapes for instance, only to have the next request data from that device.

Representing himself as a student, he requested data concerning their products and manufacturing conditions.
