Is a keyboard an input device or an output device?
- Input device
- Output device
Correct Answer

A. Input device

Explanation

A keyboard is considered an input device because it allows users to input data into a computer system. Users can type letters, numbers, and other characters using the keyboard, which is then processed and displayed on the computer screen. The keyboard does not produce any output on its own, but rather facilitates the input of information.

Is a mouse an input device or an output device?
- Input device
- Output device
Correct Answer

A. Input device

Explanation

A mouse is classified as an input device because it allows the user to interact with a computer by providing input in the form of movement and clicks. The movements and clicks are then translated into commands or actions by the computer. The mouse does not produce any output on its own, but rather facilitates the input process for the user.

Numerical representation of information using 1s and 0s.
- Input device
- Analog information
- Data storage device
- Binary code
- Hard drive
Correct Answer

A. Binary code

Explanation

Binary code is the correct answer because it refers to the numerical representation of information using 1s and 0s. This code is used in computers to represent data and instructions, with each digit in the code representing a binary digit (bit). It is a fundamental concept in computer science and is used extensively in various aspects of computing, such as data storage, processing, and communication.

Is a monitor an input device or an output device?
- Input device
- Output device
Correct Answer

A. Output device

Explanation

A monitor is an output device because it displays information from the computer to the user. It takes the electronic signals from the computer and converts them into visual images on the screen, allowing the user to see the output of their actions or the information being processed by the computer. The monitor does not take any input from the user or interact with the computer in any way, making it solely an output device.

7.

Are headphones an input device or an output device?
- Input device
- Output device
Correct Answer

A. Output device

Explanation

Headphones are classified as an output device because they convert electrical signals from a computer or audio device into sound waves that can be heard by the user. They receive audio information from the device and deliver it directly to the user's ears, allowing them to listen to music, videos, or any other audio content. Therefore, headphones do not provide any input to the device but rather output the audio generated by it.

Acronym for "Compact Disk Read-Only Memory," designed to store electronic data.
- Analog information
- Disk drive
- Data storage device
- CD-ROM
- Input device
Correct Answer

A. CD-ROM

Explanation

CD-ROM stands for Compact Disk Read-Only Memory. It is a data storage device that is designed to store electronic data. CD-ROMs are commonly used to distribute software, games, and multimedia content. They are read-only, meaning that data can be read from them but not written or modified. CD-ROMs are not analog information, disk drives, or input devices, but rather a specific type of data storage device.

Is a microphone an input device or an output device?
- Input device
- Output device
Correct Answer

A. Input device

Explanation

A microphone is considered an input device because it is used to capture sound waves and convert them into electrical signals that can be processed by a computer or other audio devices. It allows users to input their voice or other audio signals into a system for recording or communication purposes.

Is a scanner an input device or an output device?
- Input device
- Output device
Correct Answer

A. Input device

Explanation

A scanner is considered an input device because it is used to convert physical documents or images into digital format, which can then be stored, manipulated, or printed. It allows users to input information from physical sources into a computer system. Scanners work by capturing the image or text on the document and converting it into a digital file that can be processed by the computer. Therefore, the correct answer is input device.

Information made of varying frequencies of sound and light waves.
- Input device
- Binary code
- Data storage device
- Analog information
- Output device
Correct Answer

A. Analog information

Explanation

Analog information refers to data that is represented by varying frequencies of sound and light waves. It is not converted into binary code and can be directly processed by input devices or output devices. Therefore, analog information is the correct answer in this context.

Storage device inside the main computer body that includes both the part that does the saving and the medium where information is stored.
- Input device
- CD-ROM
- Data storage device
- Disk drive
- Hard drive
Correct Answer

A. Hard drive

Explanation

A hard drive is a storage device inside the main computer body that includes both the part that does the saving and the medium where information is stored. It is a non-volatile storage device that stores and retrieves digital information using magnetic storage and rotating platters. It provides a large amount of storage capacity for the computer and is commonly used for long-term data storage.

Translates binary coded information from the processor into analog information you can understand.
- Hard drive
- Output device
- CD-ROM
- Input device
- Data storage device
Correct Answer

A. Output device

Explanation

An output device is a peripheral device that translates binary coded information from the processor into analog information that can be understood by the user. It takes the processed data and displays or presents it in a format that is readable or usable by humans. In this case, the correct answer is "output device" because it accurately describes the function of translating binary information into analog information for user comprehension.

Translates the analog information you enter into binary code so that the processor can understand what you want.
- Binary code
- Input devices
- Hard drive
- Output devices
- Disk drive
Correct Answer

A. Input devices

Explanation

Input devices are responsible for translating analog information into binary code, which can be understood by the processor. This allows the processor to interpret and execute the commands or actions that the user wants. Therefore, input devices play a crucial role in converting the user's input into a format that the computer can process and respond to.

Data storage device that saves the information using a medium.
- Disk drive
- CD-ROM
- Input device
- Hard drive
- Binary code
Correct Answer

A. Disk drive

Explanation

A disk drive is a data storage device that saves information using a medium, such as a disk or a hard disk. It is capable of reading and writing data onto the disk, allowing for the retrieval and storage of information. Other options like CD-ROM, input device, and binary code do not specifically refer to a data storage device that saves information using a medium, making them incorrect choices.
