## Definition

a way of saving computer data as separate pieces called objects. Each object includes the data itself, extra information about it, and a unique ID so it is easy to find in a large system.

For teachers: a computer data storage architecture that manages data as objects, as opposed to other storage architectures like file systems which manage data as a file hierarchy. Each object typically includes the data itself, a variable amount of metadata, and a unique identifier.

## Examples

- Cloud companies often use object storage for photos and videos.
- The engineering team moved their backup archives to object storage to take advantage of its massive scalability and lower costs.
- Unlike traditional block storage, object storage allows for extensive custom metadata, enabling more efficient data indexing and retrieval across distributed cloud environments.

## Usage notes

- Often functions as a compound noun in technical and computing contexts.
