What is an API and why is it important?

• An API is a set of rules for software communication, and it is important for enabling integration and innovation.

• An API is a type of hardware device.

• APIs are only used for mobile applications.

• An API is a programming language for developers.

Describe the process of writing a new API.

• Design user interface, write user stories, implement, test

• Define purpose, create a database, implement security, deploy

• Define purpose, design endpoints, implement, test, document.

• Define purpose, create a marketing plan, implement, review

What are real-time reactions in the context of APIs?

• Real-time reactions are delayed responses from APIs.

• Real-time reactions are periodic updates sent by APIs.

• Real-time reactions are immediate responses or updates provided by APIs in response to events.

• Real-time reactions are static data provided by APIs.

List some other protocols commonly used with APIs.

• HTTP, HTTPS, WebSocket, gRPC, MQTT, AMQP

• FTP

• SMTP

• POP3

What techniques can be used for effective memory management in embedded code?

• Using only global variables for all data

• Implementing complex data structures without optimization

• Garbage collection and automatic resizing

• Techniques include static allocation, dynamic management, memory pooling, fixed-size structures, and data type optimization.

How does performance impact the usability of an API?

• Performance has no effect on API usability.

• Usability is solely determined by API documentation.

• Performance issues can enhance user satisfaction.

• Performance directly affects the usability of an API by influencing response times and user satisfaction.

What strategies can be employed to optimize battery life in embedded systems?

• Use outdated coding practices

• Disable all power-saving features

• Employ low-power modes, efficient coding, hardware optimization, dynamic voltage scaling, and sleep modes.

• Increase screen brightness

Name a few popular libraries used for API development.

• React.js

• Vue.js

• Angular

• Express.js, Flask, Django, Spring Boot

What debugging techniques are essential for embedded code?

• Hardware debugging, print statements, oscilloscopes, simulation tools, code reviews, static analysis.

• Memory leaks detection

• User interface testing

• Network latency analysis

Explain the role of documentation in API development.

• Documentation is primarily for marketing purposes.

• Documentation is optional and can be ignored.

• Documentation is only necessary for internal use.

• Documentation is crucial in API development as it provides clear instructions and information for users to effectively utilize the API.
