    Study Notes

    Storage Systems

    • A storage medium is a physical material that holds data, such as a hard drive or flash drive.
    • A storage device is a peripheral that reads and writes data to a storage medium, such as a hard drive or solid-state drive.

    Characteristics of Storage Systems

    • Portability and volatility are characteristics of a storage system that refer to how portable and stable the system is.
    • Data access refers to the process of retrieving or writing data to a storage medium.

    Storage Technology

    • The storage controller determines the type of technology used for storing data, such as magnetic, optical, or solid-state.

    Internal Storage Devices

    • The main advantage of internal storage devices is that they are faster and more reliable than external devices.

    Random Access vs. Sequential Access

    • Random access storage devices allow data to be retrieved from any location on the storage medium, such as a hard drive.
    • Sequential access storage devices require the system to read data in a specific order, such as a tape drive.

    Volatile vs. Non-Volatile Storage

    • Nonvolatile storage media retain their data even when power is turned off, such as a hard drive or solid-state drive.

    Data on Storage Media

    • Data refers to anything stored on a storage medium, including programs, documents, digital images, songs, and more.
