Which of the following is NOT a function of the CPU?

The CPU, or Central Processing Unit, is the primary component of a computer responsible for interpreting and executing instructions. It plays a crucial role in performing calculations, processing data, and managing computer resources such as memory, input/output devices, and overall system operations.

Data storage is a function that falls outside the responsibilities of the CPU. While the CPU can be involved in accessing and manipulating data that is stored in memory or other storage devices, it does not itself serve as a storage medium. Instead, data storage is typically managed by separate components, such as hard drives, solid-state drives, and RAM, which are specifically designed for long-term data retention and fast access.

In contrast, performing calculations, processing data, and managing resources are core functions of the CPU, as it actively executes instructions and processes information through its arithmetic logic unit (ALU) and control unit. This distinction highlights why data storage is not a function of the CPU.
