A cloud database is characterized by its accessibility over the Internet, allowing users to interact with the database remotely from various locations and devices. This type of database is hosted on cloud computing platforms, making it scalable and flexible for users who need to store and manage data without the constraints of local hardware limitations.

In contrast, when considering the other options, a database installed on personal computers is tied to physical devices and lacks the remote accessibility of cloud databases. A database that can only be accessed locally restricts user access to a single location, contradicting the mobility and convenience that cloud databases offer. Lastly, a database that requires manual updates does not align with the automated and managed nature often found in cloud database services, where updates can be handled by the service provider without user intervention. This highlights the significant advantages a cloud database brings in terms of accessibility, scalability, and maintenance.
