Which hardware component handles the operations performed on data?

Peripheral devices are external components that connect to the computer to add functionality, such as printers, keyboards, and mice. While they enable user interaction and data input/output, they do not perform the core operations on data within the computer. Their role is supportive rather than operational.

Secondary storage refers to devices like hard drives and SSDs where data is stored permanently or semi-permanently. Although crucial for data retention, secondary storage does not execute operations on data; it merely provides a place to read from and write to, relying on the processing unit to handle operations once data is accessed.

Primary storage, typically consisting of RAM, temporarily holds data and instructions that the CPU needs while performing tasks. While it is essential for quick access to data, it does not perform operations itself; instead, it supports the processing unit by providing fast access to the information needed for execution.
