### 1. Client (`google/cloud/storage/client.py`)
The `Client` class is the entry point for interacting with the Google Cloud Storage API. It handles authentication and project configuration.
- **Key Responsibilities**:
- Authenticating with Google Cloud.
- Creating, retrieving, and listing buckets.
- Managing batch operations.
- Creating HMAC keys.

### 2. Bucket (`google/cloud/storage/bucket.py`)
The `Bucket` class represents a Google Cloud Storage bucket. It provides methods to manage the bucket itself and the objects (blobs) within it.
- **Key Responsibilities**:
- Creating and deleting the bucket.
- Configuring bucket properties (ACLs, lifecycle rules, versioning, CORS, website configuration, etc.).
- Creating, listing, getting, and deleting blobs.
- Managing IAM policies for the bucket.

### 3. Blob (`google/cloud/storage/blob.py`)
The `Blob` class represents an object (file) within a GCS bucket. It provides methods to upload, download, and manage the object.
- **Key Responsibilities**:
- Uploading data (from file, filename, or string).
- Downloading data (to file, filename, bytes, or text).
- Managing object metadata and ACLs.
- Deleting the object.
- Generating signed URLs for temporary access.

### 4. Batch (`google/cloud/storage/batch.py`)
The `Batch` class allows grouping multiple API calls into a single HTTP request. This is useful for performing multiple operations (like patching or deleting multiple blobs) efficiently.
- **Key Responsibilities**:
- Accumulating multiple requests.
- Sending them in a single `multipart/mixed` HTTP request.
- Processing the responses.

### 5. Transfer Manager (`google/cloud/storage/transfer_manager.py`)
