What is the primary function of storage in a computer system?

The primary function of storage in a computer system is to hold and retain data, ensuring that information is preserved for use when needed. Storage allows data to be recorded, accessed, and retrieved even when the computer is powered off. This is a crucial aspect of a computer's operation, enabling users to save files, programs, and other information for future retrieval. Internal memory, or primary storage, is where data is temporarily held for quick access during processing tasks, but secondary storage, such as hard drives and SSDs, allows for long-term retention of larger volumes of data.

In contrast, other functions listed do not pertain to storage directly. Processing data and executing commands relate to the CPU's role in executing operations rather than storing information. Providing power involves the computer's power supply and is critical for system operation but does not relate to data storage. Transmitting data across networks pertains to data communication and networking tools rather than storage functionalities. Thus, the correct choice highlights the central role of storage in maintaining and organizing data within a computer system.
