In regulated industries like pharmaceuticals and healthcare, computer system validation ensures digital tools meet strict requirements. This process verifies that software operates reliably, safeguarding data integrity and patient safety. Regulations such as 21 CFR Part 11 and EU Annex 11 mandate validation to prevent costly FDA penalties—averaging $2.4B for non-compliance. Properly validated systems maintain accurate…
Early computing relied on manual processes before modern operating systems existed. Machines like ENIAC used plug boards for calculations, requiring physical rewiring for each task. These massive devices performed single operations at a time, lacking the flexibility we expect today. Modern hardware still boots using BIOS firmware, but this basic system handles only startup checks….
