GENERATIES COMPUTERS
Opgedeeld o.b.v. hardware-evoluties
2.1 EERSTE GEoERATIE (’40 – ’56)
- Vacuümbuizen supergrote computers
- Hitte, duur, groot, onbetrouwbaar (heel snel kapot)
- Input: ponskaarten (= metalen kaart met gaten)
- Output: printouts
- Voorbeelden: Eniac, Edvac, Mark I, IBM-650, IBM-701, Univac
2.2 2E GEoERATIE (’56 – ’63)
- Transistoren, compacter, minder hitte, energiezuiniger, duur,
betrouwbaarder, sneller, programmeertalen (Cobol)
- Input: ponskaarten & magneetbanden
- Output: print
- Voorbeelden: IBM 1620, IBM 7094, CDC 1604, CDC 3600, Univac 1108
