Computer Input And Output Devices And Their Functions

Computer input and output devices are important for the effective functioning of a computer system. The input device is used to provide data and commands to the computer, while the output device is used to display the results of the computer’s operations.

There are many different types of input and output devices, each with its own set of features and functions. The most common input devices are the keyboard and mouse, while the most common output devices are the monitor and printer.

The keyboard is used to enter data and commands into the computer. It is a physical device that is typically attached to the computer’s main unit. The keyboard has a number of keys that are used to type text, numbers, and special characters. It also has a number of control keys that are used to perform various tasks, such as opening and closing programs, and moving the cursor on the screen.

The mouse is a pointing device that is used to control the movement of the cursor on the screen. It is a small handheld device that is typically connected to the computer via a USB port. The mouse has two buttons and a scroll wheel that is used to scroll through documents and webpages.

The monitor is the main output device of a computer system. It is a large flat screen that is used to display the results of the computer’s operations. The monitor typically has a resolution of 1920×1080 pixels, which is sufficient for most tasks.

The printer is used to print documents and images from the computer. It is a physical device that is typically connected to the computer via a USB port or a network connection. The printer has a number of different print cartridges that are used to print text, images, and photos.
