Answer 1

In the MongoDB connection string, 'Travel' designates the database name that the user wishes to connect to. It is part of the standard format for connection strings and follows the server address and port number in the string.

Step-by-step explanation:

In the MongoDB connection string let url='mongodb://localhost:27017/Travel';, the word 'Travel' represents the database name. The connection string is a standard format for defining connections to a MongoDB server. Here's how it breaks down:

mongodb: - the protocol specification.localhost - the server address where MongoDB is running, typically referring to the local machine.27017 - the default port on which MongoDB listens for connections.Travel - the name of the database we want to connect to within MongoDB.

The other options, like server address and collection name, have specific different meanings in the context of MongoDB. For example, the server address is given by 'localhost' in this string, and the collection name would be specified in a different part of a MongoDB operation, not within the connection string.
