Computer inputs and outputs (I/O) are the means by which a computer exchanges information with the outside world. There are many different types of I/O, but the most common are input devices such as a keyboard and mouse, and output devices such as a monitor and printer.
Input devices allow you to enter information into the computer, such as when you type on the keyboard or click on the mouse. Output devices display information that the computer has processed, such as the text you are currently typing or the image on the monitor.
Most computers have a variety of input and output devices, which can be used together to create a complete computing system. For example, you can use a keyboard and mouse to input information into the computer, and then use the monitor to view the results. Or, you can use the printer to output information that the computer has processed.
It’s important to understand the different types of computer I/O so that you can select the devices that are best suited for your needs. Let’s take a closer look at the most common types of computer input and output devices.
Input Devices
The most common input devices are the keyboard and mouse. The keyboard is used to type text and enter commands, and the mouse is used to move the cursor on the screen and select items.
Other common input devices include the touchpad, which is a small pad located on the keyboard that is used to control the cursor by moving your fingers, and the trackball, which is a ball on a stick that you use to move the cursor.
Input devices are typically connected to the computer via a port, which is a specialized connector that allows the device to communicate with the computer. The most common input ports are the USB port and the serial port.
Output Devices
The most common output devices are the monitor and printer. The monitor is used to display information that the computer has processed, such as the text you are currently typing or the image on the screen. The printer is used to print out documents and other information that the computer has processed.
Output devices are typically connected to the computer via a port, which is a specialized connector that allows the device to communicate with the computer. The most common output ports are the VGA port and the USB port.
