Computer input refers to the data and commands that users provide to a computer system. This can be done through various devices, such as a keyboard, mouse, or touchscreen. Input allows users to interact with software applications and perform tasks, such as typing documents or navigating websites. Different types of input can also come from sensors or microphones, which capture data from the environment. For example, a camera can input images, while a scanner can digitize physical documents. Overall, computer input is essential for enabling communication between users and computers.
