Pathweb

The Pathweb was the (unnaturally) shared intelligence of the Daleks, containing information on their history and experiences. It was more a telepathic link than it was a true hive mind.

It is unknown when the pathweb was developed but it was possessed by Daleks present on Aridius, Kembel, Vulcan, Spiridon, and Exxilon. The Doctor had attempted to hack into the pathwed but was unsuccessful. Several inmates of the Dalek Asylum attacked him upon recognising him, but Oswin Oswald, already part of the pathweb because of her conversion into a Dalek, deleted all information connected with the Doctor. Any memory of the Doctor within the Dalek race was forgotten. (DW: Asylum of the Daleks)


 * The pathweb could explain how Daleks on Vulcan and Necros could recognize the Doctor in different incarnations.
