A mouse,touch screen, and a trackball are all examples of _______________________
Correct Answer
B. Input Devices
Explanation
A mouse, touch screen, and trackball are all examples of input devices. Input devices are hardware components or peripherals that allow users to interact with and provide input to a computer or electronic device. These devices enable users to input data, control the cursor or pointer on a screen, and perform various tasks such as navigating, selecting, and interacting with software and applications.
5.
Keyboard is known as an input device.
Correct Answer
A. True
Explanation
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.
6.
The input device that has the monitor screen covered with a flexible layer is the
Correct Answer

Therefore, the correct answer is touch screen.
7.
The device that would be used to read a mark-sense answer sheet for this test would be
Correct Answer
D. Character or mark recognition device
Explanation
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.
8.
The scanning technology used in banks to read the numbers at the bottom of checks is
Correct Answer
A. MICR
Explanation
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.
9.
Input devices take data from the computer.
Correct Answer
B. False
Explanation
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.
