An S3 bucket in AWS (Amazon Web Services) is a logical container for storing objects (files, data, and metadata) in Amazon Simple Storage Service (Amazon S3). It serves as the foundational storage unit in AWS and allows you to store, retrieve, and manage data in a scalable, secure, and cost-effective manner.
A pre-signed URL in the context of an AWS S3 bucket usually refers to a pre-signed URL. A pre-signed URL allows users to access a specific object in an S3 bucket without requiring direct permissions to the bucket.

This is particularly useful when you want to grant temporary, secure access to a private object in S3 for downloading or uploading purposes.
