About Input / display device

Input and display devices refer to the equipment or devices used for interaction with computers or electronic systems, allowing users to input data and display output information. These devices serve as a vital link between the system and the user. Input devices are used to transfer data or commands from the user to the system. Common input devices include keyboards, mice, touchscreens, voice recognition devices, cameras, and sensors. These devices convert the user's actions or instructions into a form that the computer can understand. For example, a keyboard is used to input letters and numbers, while a touchscreen allows users to perform actions by touching the screen. On the other hand, display devices are used to visually present information output from the system. The most common display devices are monitors or screens. Monitors display text, images, graphics, and other information to the user. Additionally, digital signage and LED boards are also included in display devices, and they are commonly seen in public spaces and commercial establishments. Input and display devices work together to process and operate data efficiently, supporting users in their tasks. In modern systems, where visual information delivery is often essential, these devices have become indispensable.
