Ajith running an internet cafe. Identify the economic activity mentioned here

Ajith is essentially providing a service.

Explanation:

A service is an economic transaction in which the buyer obtains a benefit from the seller, but his benefit is not a good, like a product, or a machine.

Ajith provides a service to his customers: the use of a computer to connect to the internet for a specific period of time. The period of time is determined by the amount the customer pays: the higher the amount, the more time the customer is allowed to connect.

As can be seen, the customers do not obtain any product from the transaction, they simply get the right to connect to the internet, for that reason, it is a service what they are being provided with.
