Partitioning is a technique used in Teradata to horizontally divide a large table into smaller, more manageable pieces called partitions. Each partition contains a subset of the rows in the table and is stored on one or more AMPs (Access Module Processors) in the system.
Explanation:

Explanation:
A non-unique secondary index (NUSI) operation in Teradata is always an ALL AMPs operation.
Explanation:
Teradata is a database management system that can run on various operating systems. It supports multiple platforms including Windows, Linux, and z/OS (IBM mainframe operating system). Therefore, the correct answer is "All of the above."
Teradata provides a consistent database experience across all these platforms, allowing customers to choose the operating system that best suits their needs. The choice of operating system may depend on factors such as performance, scalability, reliability, security, and cost. Teradata also provides client software for Windows and Linux that allows users to connect to the Teradata database.
