lochkartencomputer
Lochkartencomputer, also known as punched card computers, were early computing devices that utilized punched cards for both program instructions and data input. These cards, typically made of paper or cardstock, contained information represented by the presence or absence of holes in specific positions. A hole at a particular location on the card signified a "1" or an "on" state, while the absence of a hole represented a "0" or an "off" state. These machines were instrumental in the development of computing before the widespread adoption of magnetic storage and keyboards.
The operation of a lochkartencomputer involved feeding these punched cards through a reader. The reader would
Examples of prominent lochkartencomputer systems include early tabulating machines and some of the first electronic computers.
