What is the primary purpose of the Media Transfer Protocol (MTP)?

The primary purpose of the Media Transfer Protocol (MTP) is to facilitate the transfer of media files like music, videos, and images between devices. Although option A highlights music files specifically, MTP is indeed designed for a broader range of media types, primarily focusing on the synchronization and management of multimedia content between devices such as digital audio players, digital cameras, and other portable media devices.

MTP operates over USB connections and is commonly used in devices like smartphones and portable media players to enable the transfer of various types of media files without exposing the file system of the device to the user. This allows users to manage their media content more effectively and ensures that the file transfer process is standardized and user-friendly.

While the other options may seem relevant in some contexts—such as transferring photographs or videos—MTP encompasses all these functionalities, not limited to just one type of media file. Additionally, transferring files only within a local network does not align with MTP, which is specifically used for media file transfers regardless of the network context.
