A4: User authentication can be implemented using methods like password hashing, token-based authentication (e.g., JWT), and integrating authentication libraries or services.

A5: JWT is a compact, URL-safe token used for securely transmitting information between parties as a JSON object, commonly used for authentication and authorization.

A6: User sessions can be managed using session cookies or tokens. Sessions typically store user data and manage state across multiple requests.

A7: Common practices include using strong, hashed passwords, implementing multi-factor authentication (MFA), and ensuring secure storage of sensitive data.

A8: Authorization roles and permissions can be managed by defining user roles, assigning permissions to these roles, and checking these permissions before granting access to resources.

A9: Authentication verifies who you are, while authorization determines what you are allowed to do after being authenticated.

A10: Securing an application involves practices like input validation, using HTTPS, protecting against cross-site scripting (XSS) and SQL injection attacks, and regularly updating dependencies.

A1: In Module 10, you will learn how to build and consume APIs, including creating RESTful APIs, handling API requests and responses, and integrating APIs into applications.

A2: An API (Application Programming Interface) is a set of rules and protocols for building and interacting with software applications, allowing different systems to communicate with each other.

A3: A RESTful API is an API that follows REST (Representational State Transfer) principles, using HTTP requests to perform CRUD operations on resources.

A4: API requests are handled by defining endpoints that accept HTTP methods like GET, POST, PUT, and DELETE. Responses are sent back in formats like JSON or XML.

A5: API authentication involves verifying the identity of users or systems accessing the API, often through methods like API keys, tokens, or OAuth.

A6: APIs can be tested using tools like Postman or cURL, which allow you to send requests and inspect responses. Automated testing can also be performed using frameworks like Mocha or Jest.

A7: API versioning is the practice of managing changes to the API by assigning version numbers to different iterations, allowing clients to continue using a stable version while new versions are developed.

A8: API rate limiting is managed by setting limits on the number of requests a user or system can make within a specific time frame to prevent abuse and ensure fair usage.

A9: API documentation provides detailed information about the API's endpoints, request formats, response formats, and usage examples, helping developers understand and use the API effectively.
