Parallel Port:- For many years, the most popular
type of interface available on computers was the parallel interface. Parallel
ports can send or receive 8 bits or 1 byte at a time.
Device name:- Printer, Scanner, etc.

1) What does an input device send to a computer?
Ans:- What an input device sends to a computer depends on their
device. Additionally, all input devices send data from the device over a cable
or wireless transmission to the computer. For example, as you move a computer
mouse, the data sent to the computer is the X and Y axis movements used to
display the mouse cursor on the screen. You can see a live example of this on
our “x” axis definition.
2) Why does a computer need an input device?

with me and add new information to a computer. For example, if a computer had
no input devices, it could run by itself but there would be no way to change
its settings, fix errors, or other various user interactions. Also, if you
wanted to add new information to the computer (e.g., text, command, document,
picture, etc.), you wouldn't be able to do so without an input device.
