What is the main difference between a Node.js stream and a traditional file I/O operation?
Streams are faster and more efficient than traditional file I/O operations
Streams can only be used with text files, while traditional file I/O operations can be used with any type of file
Streams allow data to be processed in real-time, while traditional file I/O operations read the entire file into memory at once
Streams can only be used with Node.js applications, while traditional file I/O operations can be used with any programming language
Streams allow data to be processed in real-time, while traditional file I/O operations read the entire file into memory at once

What is the main difference between the Node.js http module and the Node.js express module?
The http module is only used for creating servers, while the express module is only used for creating clients
The http module is written in C++, while the express module is written in JavaScript
The http module is lower level and provides a basic set of features, while the express module is higher level and provides a more comprehensive set of features
The http module is used for creating command-line tools, while the express module is used for creating web applications
