Question

From where, the CPU in a computer retrieves data :

• A. Secondary Memory
• B. Auxiliary memory
• C. Main Memory
• D. None of these

Answer 1

Answer:

C. Main Memory

• The CPU (Central Processing Unit) retrieves data from the main memory (also called primary memory or RAM). Main memory stores the data and instructions that the CPU needs immediately while executing programs. It provides fast access compared to secondary (auxiliary) storage such as hard disks or SSDs, which are slower and used for long-term storage. When a program runs, its instructions and required data are loaded from secondary storage into main memory; the CPU then reads from and writes to main memory as it processes those instructions. Therefore, the correct choice is Main Memory.
