Explain what the term partition means in the context of databases or distributed systems.

In the context of databases and distributed systems, the term "partition" refers to dividing data into separate parts (partitions) that can be stored and processed independently.

In databases, partitioning helps improve performance and manageability by splitting large tables into smaller logical segments based on a specific criterion (e.g., date or value range).

In distributed systems, a partition is a part of the overall dataset stored on a separate node or group of nodes. This allows for horizontal scaling of the system and increases fault tolerance.

Example: In a distributed database, keys can be partitioned based on a hash of the key, and each partition is served by a separate server.
