Which type of client typically requires more storage space?

Fat clients typically require more storage space because they are designed to perform extensive computing tasks on the user's device rather than relying heavily on a central server. This architecture allows them to store not only the operating system and essential software applications but also the necessary data and files locally. Since fat clients support applications that may require significant processing capabilities and can run independently, they need additional storage to accommodate these resources.

In contrast, thin clients rely on a remote server to handle most processing and store applications and data, leading to a significantly reduced need for local storage. Cloud clients, similarly, depend on cloud services for storage and processing, which means they utilize minimal local resources. Smart clients blend features of both fat and thin clients, but they usually do not require as much local storage as a fat client because they often manage only essential data locally while connecting to remote resources for more extensive functionalities.
