C) Bluetooth technology
D) hard copy

Accepted Answer

Speech, sound effects, and music are examples of audio input, which refers to any sound that is recorded or transmitted into a computer or other digital device. Specialized output devices are hardware components that allow a computer to communicate with the external world, such as printers or monitors. Bluetooth technology is a wireless communication protocol used for connecting devices. Hard copy refers to a physical, printed version of a document or image.

Question 9

Which of the following is NOT a special-purpose input port?
A) SCSI
B) IrDA
C) Bluetooth
D) PDA

Accepted Answer

PDA is not an input port, but a type of handheld electronic device. SCSI, IrDA, and Bluetooth are all types of special-purpose input ports used for connecting devices such as scanners, printers, and mobile devices to a computer.

Question 10

Remote controls are a type of specialized ____.
A) environmental probe
B) output device
C) input device
D) security device

Accepted Answer

Remote controls are input devices that allow users to send commands or instructions to a device from a distance. They are commonly used for televisions, sound systems, and other electronic devices.

Question 11

A stylus would be used to write on a(n) ____.
A) environmental sensor
B) PDA
C) monitor
D) fingerprint scanner

Accepted Answer

A stylus is commonly used to write on a PDA (personal digital assistant), which is a device that can be used for taking notes, managing contacts, and other organizational tasks. While a stylus may be used on other devices such as a touchscreen monitor or fingerprint scanner, these are less common applications of a stylus. An environmental sensor is a device that measures conditions in the environment, and would not typically require a stylus for operation.

Question 12

Printer speed is measured in ____.
A) RAM
B) characters per second
C) pages per minute
D) dots per inch

Accepted Answer

Printer speed is most commonly measured in pages per minute (ppm), which indicates how many pages a printer can print in one minute. Therefore, the correct answer is C.

Question 13

Which of the following uses the synchronized positioning of light-emitting and sensing devices to detect user input?
A) Biometric keyboard scanner
B) Laser virtual keyboard
C) Fingerprint scanner
D) Touch display screen

Accepted Answer

The synchronized positioning of light-emitting and sensing devices is used in laser virtual keyboards to detect user input. Biometric keyboard scanners use biometric technology to identify users, fingerprint scanners use fingerprint recognition, and touch display screens use touch-sensitive surfaces to detect user input.

Question 14
