The history of computing at CERN is about hardware, software, people, network, communications, accelerators, data-handling...
This section is an eclectic stockpile of material covering various aspects of the computing history at CERN. It is by no means a complete history, and new elements are added all the time as they come to light.
For photographs, see the CERN PhotoLab Archives, we have some at the IT Archive Galleries, and the 'Photos from..." (in the column to the right of this page). The "IT Archive Galleries" and CERN PhotoLab Archives are work-in-progress; more material is being added all the time as we dig deep into forgotten archives.
For more information on CERN's computing history, contact our Computing History at CERN (aka Cath Noble) for help.
See the excellent presentation by David Williams from CHEP 2004 for a comprehensive and revealing look at Computing at CERN since CERN's inception in 1954.

- 25 years ago: the strategic move to PCs in high-energy physics by Sverre Jarp, September 2020.
In September 1995, 25 years ago, a paper entitled “The PC as Physics Computer for LHC?” was presented at the CHEP-95 conference. It paved the way to a new era in high-energy physics computing. One of its authors, Sverre Jarp, recalls.
