Which storage type stores data as distinct units called objects?

• A. Data Storage
• B. Filed-Based Storage
• C. Object Storage
• D. Storage Model

Answer: (C)

Object storage stores data as distinct units called objects. Each object contains the data itself, a metadata set describing the item, and a unique identifier that lets you retrieve it without relying on a traditional file path. This structure enables massive scalability and flexible management of unstructured data, because you can add more storage nodes and use rich metadata to locate and organize items across a distributed system. There’s no need for a hierarchical directory tree, which is why object storage is well suited for cloud-scale storage and web-based access patterns.

In contrast, file-based storage uses a directory-and-file hierarchy with paths, so data is accessed via filenames and folders and metadata is more limited. Block storage breaks data into fixed-size blocks addressed by position on a volume, with a separate file system providing structure, which makes it great for databases and performance-intensive tasks but not as metadata-rich or scalable in the same way. The term that describes storing data as these self-contained objects is object storage.
