Which one of these is a storage device?

Category: Miscellaneous Indian Gk

Hint: Think about which device can hold data for later use.

Correct Answer: A) Pen Drive.

Exam Relevance: SSC, UPSC, Bank PO, CLAT

Difficulty: Easy

Explanations:

A storage device is a hardware component that is designed to store digital data. This data can be retrieved and used at a later time. Storage devices are essential for saving and managing information on a computer or other digital devices. Examples of storage devices include hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives (also known as pen drives or thumb drives), and external hard drives.

Let's delve into the specific types of devices mentioned in the question:

Pen Drive (Option A): A pen drive, also known as a USB flash drive, is a small, portable storage device that uses flash memory to store data. It connects to a computer via a USB port and can be used to transfer files between computers, store backups, or carry data on the go. Pen drives are non-volatile, meaning they retain data even when not powered, making them a reliable storage solution.

Keyboard (Option B): A keyboard is an input device that allows users to enter data into a computer. It consists of a set of keys that, when pressed, send signals to the computer to perform specific functions or input text. Keyboards do not have the capability to store data; they are purely for input purposes.

Monitor (Option C): A monitor is an output device that displays visual information from the computer. It converts electronic signals into visual images that can be seen by the user. Monitors do not store data; they only display the output generated by the computer's processing and graphics capabilities.

Mouse (Option D): A mouse is another input device that is used to control the cursor on a computer screen. It allows users to interact with graphical user interfaces (GUIs) by clicking, dragging, and scrolling. Like the keyboard, the mouse does not store data; it only sends input commands to the computer.

In summary, the pen drive is the only storage device among the options provided. It is designed to hold digital data and can be used to transfer files between different devices. The other options—keyboard, monitor, and mouse—are not storage devices; they are either input or output devices that do not have the capability to store data.

Option Analysis:

Option A: This is the correct answer. A pen drive is a storage device that can hold digital data and is portable. It is used to store and transfer files between computers and other devices.
Option B: This is incorrect. A keyboard is an input device used to enter data into a computer. It does not store data; it only sends input to the computer.
Option C: This is incorrect. A monitor is an output device that displays information from the computer. It does not store data; it only shows the output.
Option D: This is incorrect. A mouse is an input device used to control the cursor on a computer screen. It does not store data; it only sends input commands to the computer.

Mnemonic: Remember: "P" for Pen Drive, "P" for "Portable Storage."
