A computer punched card reader or just computer card reader is a computer input device used to read computer programs in either source or executable form and data from punched cards. A computer card punch is a computer output device that punches holes in cards. Sometimes computer punch card readers were combined with computer card punches and ...
The XT/370 was an IBM Personal Computer XT (System Unit 5160) with three custom 8-bit cards. The processor card (370PC-P), [ 3 ] contained two modified Motorola 68000 chips (which could emulate most S/370 fixed-point instructions and non-floating-point instructions), and an Intel 8087 coprocessor modified to emulate the S/370 floating point ...
A single program deck, with individual subroutines marked. The markings show the effects of editing, as cards are replaced or reordered. Many early programming languages, including FORTRAN, COBOL and the various IBM assembler languages, used only the first 72 columns of a card – a tradition that traces back to the IBM 711 card reader used on the IBM 704/709/7090/7094 series (especially the ...
A card reader is a data input device that reads data from a card-shaped storage medium and provides the data to a computer. Card readers can acquire data from a card via a number of methods, including: optical scanning of printed text or barcodes or holes on punched cards, electrical signals from connections made or interrupted by a card's punched holes or embedded circuitry, or electronic ...
The XQD card is a memory card format primarily developed for flash memory cards. It uses PCI Express as a data transfer interface. The format is targeted at high-definition camcorders and high-resolution digital cameras.
Originally developed by the Personal Computer Memory Card International Association (), the ExpressCard standard is maintained by the USB Implementers Forum ().The host device supports PCI Express, USB 2.0 (including Hi-Speed), and USB 3.0 (SuperSpeed) [2] (ExpressCard 2.0 only) connectivity through the ExpressCard slot; cards can be designed to use any of these modes.
There are various types of expansion cards: A videocard transforms data from the computer memory into the video signal for the monitor. The videocard has its own processor, relieving the CPU of the computer; A sound card enables the computer to work with sound; A network card enables the computer to interact on a local network.
The following units were not designed to punch cards: The 1442 Model 3 attaches to an IBM 1410 or IBM 7010 computer system. It reads cards at 400 cpm. One stacker is standard on the Model 3. The 1442 Model 4 attaches to an IBM 1440 computer system. It reads cards at 400 cpm. Two stackers are standard on the Model 4.
