Disks are considered secondary storage devices because they are used for long-term data storage and are not directly accessible by the CPU. Unlike primary storage, such as RAM, which provides fast access to data that is actively being used, secondary storage devices like hard drives and SSDs store data persistently but require additional time for data retrieval. This distinction highlights the role of primary storage in facilitating immediate processing tasks, while secondary storage serves as a repository for larger volumes of data.
