Input Device Quiz Trivia Questions

The keyboard is known as an input device because it allows users to input data, commands, and text into a computer or other electronic device. It consists of a set of keys that are used to type letters, numbers, symbols, and other characters. When a key is pressed, it sends an electrical signal to the computer, which then processes and displays the corresponding character on the screen. Therefore, the keyboard serves as a primary means of input for users to interact with a computer system.

The statement "The mouse is not an input device" is incorrect. A mouse is indeed an input device as it allows users to interact with a computer by moving the cursor and selecting items on the screen. It is commonly used to navigate and control graphical user interfaces. Therefore, the correct answer is False.

The joystick is the most popular input device for computer games because it offers precise control and a wide range of motion. It allows users to manipulate game characters or objects with ease, providing a more immersive gaming experience. Joysticks are particularly well-suited for flight simulators and other games that require precise movement and control. They are also versatile, as they can be used for a variety of game genres. Overall, the joystick's popularity in the gaming community is due to its functionality, responsiveness, and versatility.

A mouse is an input device that rolls on a desktop and controls the position of the cursor on the screen. It typically has one or more buttons that can be clicked to perform various actions. The movement of the mouse is translated into corresponding movement of the cursor on the screen, allowing the user to interact with graphical user interfaces and navigate through digital content.

A touch screen is an input device that has a monitor screen covered with a flexible layer. This layer allows users to interact with the device by simply touching the screen. With a touch screen, users can perform various actions such as selecting options, typing, and navigating through menus by directly touching the screen instead of using a separate input device like a mouse or a light pen. Therefore, the correct answer is touch screen.

A mark-sense answer sheet typically contains bubbles or spaces that can be filled in with a pencil or pen. A character or mark recognition device is designed to read and interpret these marks or characters on the answer sheet. This device uses optical sensors or cameras to capture the marks and then processes the data to determine the answers selected by the test taker. Therefore, a character or mark recognition device would be the appropriate device to read a mark-sense answer sheet for this test.

Input devices are used to send data to the computer, not take data from it. These devices include keyboards, mice, scanners, and microphones, among others. They allow users to interact with the computer and input information or commands. Therefore, the correct answer is false.

MICR stands for Magnetic Ink Character Recognition, which is the scanning technology used in banks to read the numbers at the bottom of checks. This technology uses special ink that contains magnetic particles, allowing the scanning machine to accurately read and process the information on the check. OCR (Optical Character Recognition) is a different scanning technology that uses optical sensors to read printed or handwritten text, while OMR (Optical Mark Recognition) is used to detect and interpret marks on forms, such as checkboxes. GRE (Graduate Record Examination) is a standardized test for graduate school admissions and is unrelated to the scanning technology used in banks.

A POS terminal is an example of both direct entry and keyboard entry. Direct entry refers to the process of entering data directly into a system without the use of intermediate documents or sources. In the case of a POS terminal, the data is entered directly into the system using the keyboard. Therefore, both options B (direct entry) and C (keyboard entry) are correct.
