Final answer:
An input device allows entering data into a computer, such as a keyboard or mouse, while an output device conveys information from the computer to the user, like a monitor or printer. Common gadgets combining these functions include smartphones, laptops, and smartwatches, which are central to modern life.
Step-by-step explanation:
What is an Input and Output Device?
An input device is any hardware component that allows you to enter data and instructions into a computer system. Examples of input devices include keyboards, which are used for typing text, mice for navigating the user interface, microphones for audio input, and cameras for capturing images or videos.
An output device is any piece of computer hardware that conveys information to one or more people through any senses. Examples of output devices include monitors, which display images and text on the screen, printers for producing hard copies of documents, speakers for producing sound, and projectors for displaying visuals on a larger scale.
Everyday gadgets like smartphones, laptops, and smartwatches integrate both input and output functionalities. Smartphones keep us connected to the digital world by allowing us to communicate, consume media, and organize our lives; laptops enable productive work with their computing power and portable design; and smartwatches track our fitness and provide notifications. Without these inventions, our efficiency and the convenience of accessing information would be greatly impaired.
