Explanation
The most common input device is the keyboard. This is because the keyboard is widely used for inputting text and commands into computers and other electronic devices. It allows users to type letters, numbers, and symbols, as well as perform various functions using special keys. Keyboards are essential for tasks such as writing documents, sending emails, browsing the internet, and playing games. They are a fundamental component of most computer systems and are found in almost every office, school, and home setup.

Explanation
Input devices are essential for interacting with a computer. They allow users to input data, commands, and instructions into the computer system. Without input devices such as keyboards, mice, touchscreens, or microphones, it would be impossible to communicate with the computer and provide it with the necessary information to perform tasks. Therefore, the statement is true as without input devices, there would be no means of interaction with a computer.

Explanation
A barcode reader is not an output device but rather an input device. It is used to scan and read barcodes, converting the information into a digital format that can be processed by a computer. This information can then be used for various purposes such as inventory management, pricing, and tracking. Therefore, the given statement is false.

Explanation
Input devices are hardware devices that allow users to input data or commands into a computer system. They enable users to interact with the computer by providing input, such as typing on a keyboard, moving a mouse, or using a touchscreen. These devices send signals or data to the computer, which processes and interprets the input. Therefore, the statement "Input devices put information in the computer" is true as they are responsible for inputting data or commands into the computer system.

Explanation
A microphone is actually an input device, not an output device. It is used to capture sound and convert it into an electrical signal, which can then be amplified or recorded. Output devices, on the other hand, are used to present or display information to the user, such as speakers or monitors.

Explanation
A mouse, trackball, and joystick are all examples of pointing devices. These devices are used to control the movement of a cursor or pointer on a computer screen. They allow the user to interact with the graphical user interface by pointing and clicking on icons, buttons, and other elements. Pointing devices are essential for navigating and controlling computer systems effectively.

Explanation
A bar code reader is a device that reads a group of bars of different widths, which can be found on almost every product you buy. These bars are read into the computer using a wand or fixed scanner.

Explanation
The statement "Output devices are more used than input devices" is false. This is because input devices, such as keyboards and mice, are used extensively in order to provide commands and data to the computer system. On the other hand, output devices, such as monitors and printers, are used to display or produce the results of the computer's processing. While both input and output devices are essential for computer usage, input devices are typically used more frequently and extensively.

Explanation
A joystick is classified as an input device because it allows the user to provide input to a computer or electronic device. It typically consists of a lever that can be moved in different directions, and this movement is detected and translated into commands or actions by the device it is connected to. The joystick does not produce any output itself but instead sends signals to the device to control various functions or movements. Therefore, it falls under the category of an input device.

Explanation
Input devices, such as keyboards, mice, and scanners, are used to input data into a computer system. This data can be stored in the computer's memory for further processing and retrieval. Therefore, input devices can indeed be used for memory purposes.
