Answer
A computer requires both primary and secondary storage for effective data management and processing. Primary storage, such as RAM, provides fast access to data and instructions that the CPU is currently using, allowing for quick processing and execution of tasks. However, primary storage is volatile and loses its data when powered off.
Secondary storage, like hard drives or SSDs, serves as a long-term storage solution where data can be stored persistently even when the computer is turned off. This combination ensures that a computer can operate efficiently while retaining necessary data for future use.
Step 2
