Storage

Definition

Storage is a component or system used to persistently save data (files, images, videos, documents, databases) so it can be retrieved later. Examples: HDD, SSD, NAS, Cloud Storage.

What Problem It Solves

Provides long-term data retention, organization, backup, and access to information even after power is turned off.

What Happens If Not Used

Data exists only temporarily in memory (RAM) and is lost when the system shuts down, causing permanent data loss.

Easy Wording

Storage is the digital cupboard or warehouse where a computer keeps files safely for future use.

Layman Example

Your phone stores photos, videos, and documents in its internal storage so you can view them anytime, even after restarting the phone.

Technical Example

A web application stores user-uploaded images in cloud storage such as object storage (e.g., S3), while metadata is kept in a database. When users request an image, the application retrieves it from storage.
