A test of the reliability of data. <b>Check problems</b> with known results are run through computers to verify correct functioning. (<b>a</b>) A <b>summation check</b> consists of adding a set of figures and using the sum (<b>check sum</b>) to verify accuracy and completeness. (<b>b</b>) A <b>duplication check</b> requires that an operation be repeated and yield identical results when repeated. (<b>c</b>) An <b>echo check</b> is used to verify transmitted data; the data are sent back (<b>echoed</b>) to the source station for comparison with the original data. An echo check is also a technique whereby a computer prints out values of variables and data used in a program. (<b>d</b>) <b>Error-detecting checks</b> search data for forbidden combinations. A <b>parity check</b> is such a check; the number of one bits plus a parity bit must add up to an odd number for odd parity or to an even number for even parity. A <b>longitudinal parity check</b> (LPC), written at the end of a record, does for each track what the parity bit does for each byte. (<b>e</b>) A <b>validity check</b> is a verification that a figure lies within a certain permissible range.

Un test de la fiabilidad de los datos. Comprobar problemas con resultados conocidos se ejecutan a través de computadoras para verificar el correcto funcionamiento. (a) Una verificación de suma consiste en añadir un conjunto de cifras y usar la(suma de verificación) para comprobar la precisión e integridad de los datos.
