Input, Output, Processing And Storage Devices Quiz

A keyboard is considered an input device because it allows the user to input data or commands into a computer system. It is used to type text, enter commands, and navigate through various applications and programs. The keyboard sends signals to the computer, which then processes the input and produces the desired output. Therefore, the correct answer is "Input".

A mouse is considered an input device because it allows users to interact with a computer by moving the cursor on the screen and clicking on objects or icons. The mouse sends signals to the computer, which processes these signals and performs the corresponding actions. Therefore, the correct answer is "Input."

The correct answer is "Output" because a speaker is a device that produces sound or audio output. It takes the processed information from a computer or other devices and converts it into audible sound waves that can be heard by the user.

A printer is considered an output device because it takes electronic data from a computer and produces a physical copy of that information on paper or other media. It does not take input or process data, and it does not store information. Therefore, the correct answer is "Output."

A computer processor is the central unit responsible for executing instructions and performing calculations. It is the core component that carries out the processing tasks in a computer system. The processor receives input, processes it, and produces output. Therefore, the correct answer is "Processing."

The correct answer is "Output" because a monitor or screen is a device that displays information or data to the user. It is used to visually convey the results of processing or the output of a computer system.

The hard drive is a storage device because it is used to store and retrieve data on a computer. It is responsible for storing the operating system, software applications, and user files such as documents, photos, and videos. The hard drive uses magnetic storage to store data on spinning disks or solid-state memory chips. It provides long-term storage for data even when the computer is turned off.

A floppy disk is a storage device. It is used to store data and information. Floppy disks were commonly used in the past to store and transfer files. They are portable and can be easily inserted into a computer's floppy disk drive. The data on a floppy disk is stored magnetically on a thin, flexible disk. Therefore, the correct answer is "Storage".

The CPU (Central Processing Unit) is responsible for processing instructions and performing calculations in a computer system. It carries out the tasks required for data manipulation, logical operations, and arithmetic calculations. It acts as the brain of the computer, executing instructions and coordinating the activities of other hardware components. Therefore, the correct answer is "Processing."

RAM (Random Access Memory) is a type of storage device. It is a volatile memory that stores data temporarily while the computer is running. RAM allows the computer to quickly access and retrieve data, which makes it an essential component for the smooth functioning of a computer system. Therefore, the correct answer is "Storage".

The correct answer is "Input" because a scanner is a device used to input physical documents or images into a computer system. It converts the physical information into a digital format that can be processed and stored by the computer.

A web cam is considered an input device because it captures and inputs video and audio data into a computer or other device. It allows users to input live video and audio streams, which can be used for various purposes such as video conferencing, live streaming, or recording videos. Therefore, the correct answer is "Input."

The correct answer is "Storage" because a CD-Rom is a type of storage device that is capable of storing large amounts of data, such as software, documents, and multimedia files. It uses optical technology to read and write data onto a compact disc, making it an efficient and reliable storage solution.

The correct answer is "Storage" because a USB key, also known as a USB flash drive, is primarily used for storing and transferring data. It allows users to save files, documents, and other types of data onto the device, making it a convenient and portable storage solution. While it is true that a USB key can also be used for input, output, and processing purposes when connected to a computer, its main function is to provide storage capabilities.

A Touchscreen Monitor is a device that performs both input and output functions. It allows users to input data directly by touching the screen (input) and displays information (output) simultaneously. Additionally, it involves processing to interpret the touch commands, and some touchscreen devices, especially in smartphones or tablets, also have storage capabilities integrated within the device. In contrast, the CPU mainly handles processing, HDDs are primarily storage devices, and keyboards are input devices only.
