Which of these is considered storage hardware?

Storage hardware refers to devices that are used to store data permanently or temporarily. RAM, or Random Access Memory, is a type of volatile memory that allows for the temporary storage of data that the computer is actively using. It provides quick read and write access to a storage medium, making it crucial for the performance of a computer during operation.

In contrast, a monitor is a display device for visual output, a mouse is an input device for user interaction, and a speaker is an output device for sound. None of these devices are involved in the storage of data; instead, they serve specific purposes related to input and output functions in a computing environment. Therefore, RAM is most appropriately categorized under storage hardware because it plays a vital role in data management in a system.
