What type of device operates without any internal or external storage?

A thin client is a type of device designed to operate primarily by connecting to a remote server or cloud-based system for processing and storage. It relies on the server for computing power and data management, which means it does not need to have significant internal or external storage capabilities. Instead, thin clients often have minimal hardware specifications and are optimized for network-based applications. This design allows organizations to reduce costs, as thin clients can be less expensive to purchase and maintain compared to traditional computers that require more processing power and storage.

In contrast, workstations, mainframes, and servers are typically equipped with substantial internal storage and processing capabilities to handle more complex tasks and data-intensive applications. These types of devices are utilized for specific functions requiring local processing power or significant data storage, which distinguishes them from thin clients.
