What is Partitions?

In computer science, "partitions" can refer to several concepts. Broadly, it means dividing a larger entity into smaller, more manageable, and often independent units. In database systems, partitioning involves dividing a large table into smaller, more manageable pieces. This can improve query performance, manageability, and availability. In operating systems and storage, disk partitioning divides a physical hard drive into multiple logical storage units, allowing for different operating systems or file systems to coexist on the same drive or improve organization and space utilization. In distributed systems, data partitioning distributes data across multiple machines to improve scalability and fault tolerance.
