Input Devices

1. Keyboard

A keyboard is an input device with rows of keys for typing letters, numbers, and symbols into electronic devices, functioning like a typewriter but with added function keys (like Ctrl, Shift) to control computers, and can also refer to the key-based interface of musical instruments like pianos or synthesizers

2. Mouse

A mouse is a small, handheld pointing device used to control a cursor on a computer screen, allowing users to select, click, drag, and scroll through items in a graphical user interface (GUI) by moving it across a surface.

3. Joystick

A joystick is a handheld input device featuring a pivoted stick that translates its movement (tilting or pushing) into digital signals to control an object on a screen, like a cursor or character in a video game, or operate machinery, originating from aircraft controls and commonly found in gaming and simulators, often with additional buttons

4. Trackball

A trackball is a computer input device with a ball on top that you roll with your fingers or palm to move the cursor, acting like an upside-down mouse that stays stationary while the ball moves.

5. Touch Screen

A touchscreen on a computer is a display that acts as both an output (showing images) and an input device, letting users interact directly by touching the screen with a finger or stylus, replacing traditional keyboards and mice for tasks like tapping, swiping, and pinching to zoom

6. Tablet PC

A tablet computer is a portable, all-in-one mobile device with a large touchscreen, integrating display, circuitry, and battery, controlled primarily by touch (finger or stylus) for tasks like browsing, media, and apps, bridging the gap between smartphones and laptops in size and function, typically running mobile operating systems

7. Main Frame Computer

A mainframe computer is a powerful, large-scale computer system designed for critical, high-volume tasks like bulk data processing, enterprise resource planning (ERP), and massive transaction processing for large organizations (banks, governments, airlines) needing extreme reliability, security, and uptime (near 0% downtime) for essential operations
