Input refers to data entered into a computer system through input devices like a mouse or keyboard. Output is data produced by the computer through output devices like a monitor. A mouse was invented in 1963 by Douglas Engelbart and allows scrolling and right/left clicking. Keyboards were invented in 1868 and help enter text. Monitors were created in 1897 by Ferdinand Braun and display the computer's output.

I/O devices
I/O devices allow communication between a computer and the outside world by allowing data to be input into the computer from external sources and for processed data to be output from the computer. Input devices include keyboards, mice, optical mark readers, joysticks, magnetic ink character recognition readers, and bar code readers. Common output devices are monitors, speakers, and printers such as dot matrix, inkjet, daisy wheel, line, and laser printers which produce visual or audio output.
Input and output device
An input device allows a user to enter data and instructions into a computer. Common input devices include keyboards, mice, microphones, scanners, digital cameras, and webcams. Keyboards contain typing keys, function keys, and control keys to control the cursor. Mice contain buttons to select objects and scrolling wheels. Scanners are used to input photos and text into digital formats.

Input devices table
Hardware is the physical components of a computer including input devices, the CPU, and output devices. Input devices such as keyboards, mice, and digital cameras allow users to enter data into the computer. The CPU or microprocessor processes the data and executes programs. Output devices like monitors, printers, and speakers allow the computer to communicate information to the user. Software refers to the non-physical instructions that tell the hardware how to function.
Microprocessors and Microcontrollers
Input and output devices are called peripherals, with reading from a peripheral defined as an input operation and writing to a peripheral defined as an output operation. Common input devices include switches, sensors like IR, fingerprint, ultrasonic and gas sensors, and cameras, while output devices include motors, LEDs, LCDs, RAM, ROM, EEPROM, hard disks, and flash memory. An integrated circuit on a single silicon chip called a microprocessor contains an arithmetic logic unit, control unit, and internal memory registers, and examples of microprocessor brands include Shakthi, Intel, AMD, ARM, Qualcomm Snapdragon, and Apple.
