Who is the inventer of output device?

Answer 1

There isn't a single inventor of output devices, as they have evolved over time through contributions from various individuals. Early output devices, like printers, were developed in the 15th century, with Johannes Gutenberg's printing press being a significant milestone. Other output devices, such as monitors and speakers, emerged with the advancement of technology in the 20th century, influenced by numerous inventors and engineers. Thus, output devices are the result of collaborative advancements rather than the work of one individual.
