Answer 1

optical data

Step-by-step explanation:

optical data is how external data like a keyboard is processed by the computer

Answer 2

Option D: a screen display

is the correct answer.

Step-by-step explanation:

Computer input is the process of translating physical signals (light, sound, movement) into a screen display

A process mainly consists of three phases that are:

• Input
• Processing
• Output

Input can be defined as the phenomenon through which important signals are transferred with the help of peripherals (keyboard, mouse, scanner etc) into the processor.

Processing is the crucial part in which work is done on input data to produce required results.

Output is the required result of the work done by the processor or machine.

In given scenario, input signals are light, sound movement and after processing the output is a screen display.

The physical signals are the analogue signals (continuous signals) that will provide a screen display as an output. Whereas other outputs like binary signals and decimal number system can be produced by an input which digital (having discrete value) in nature.
