Which of the following is considered a direct-entry input device?
The correct option is D All of the above
optical
scanner,mouse,light pen and digitizer are considered a direct-entry input
device.
Input devices transfer
data into a computerised information system so that it can be processed. An
input device transfers data from the outside world into a computer. ... Direct
data entry devices are used when large volumes of data must be entered into the
computer quickly.
An optical scanner is an
input device using light beams to scan and digitally convert images, codes,
text or objects as two-dimensional (2D) digital files and sends them to
computers and fax machines. Flatbed scanning devices are the most popular optical
scanners.
A computer mouse is a
hand-held pointing device that detects two-dimensional motion relative to a
surface. This motion is typically translated into the motion of a pointer on a
display, which allows a smooth control of the graphical user interface. The
first public demonstration of a mouse controlling a computer system was in
1968. Originally wired to a computer, many modern mice are cordless, relying on
short-range radio communication with the connected system.
A light pen is a computer
input device in the form of a light-sensitive wand used in conjunction with a
computer's CRT display.It allows the user to point to displayed objects or draw
on the screen in a similar way to a touchscreen but with greater positional
accuracy. A light pen can work with any CRT-based display,
A graphic tablet (also
known as a digitizer, drawing tablet, drawing pad, digital drawing tablet, pen
tablet, or digital art board) is a computer input device that enables a user to
hand-draw images, animations and graphics, with a special pen-like stylus,
similar to the way a person draws images with a pencil and ...
