Which of the following input/output devices is not associated with personal computers?
Which of the following input/output devices is not associated with personal computers?
The correct option is C Punched cards
Punched cards is a input/output devices is not associated
with personal computers
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, later, other devices
to form multifunction machines. It is a input device and also a output device.
Most early computers, such as the ENIAC, and the IBM NORC, provided for punched
card input/output. Card readers and punches, either connected to computers or
in off-line card to/from magnetic tape configurations, were ubiquitous through
the mid-1970s.
Punched cards had been in use since the 1890s; their
technology was mature and reliable. Card readers and punches developed for
punched card machines were readily adaptable for computer use. Businesses were
familiar with storing data on punched cards and keypunch machines were widely
employed. Punched cards were a better fit than other 1950s technologies, such
as magnetic tape, for some computer applications as individual cards could
easily be updated without having to access a computer.
