The CPU interacts directly with the ______________ memory to perform read or write operation.

Correct option is B

The CPU interacts directly with primary memory (RAM) to perform read and write operations. Primary memory is essential for the CPU to process instructions and data quickly, as it provides a temporary space where information can be accessed rapidly. This direct connection allows the CPU to perform calculations efficiently, as data does not need to be retrieved from slower storage like secondary memory.
Important Key Points:
1. Primary Memory (RAM): RAM serves as the main memory of a computer, storing data temporarily for quick access during processing. It is volatile, meaning it loses stored information when the power is turned off.
2. Fast Access: Since RAM is directly accessible by the CPU, it provides high-speed data access, crucial for running applications and executing tasks in real-time.
3. Direct CPU Interaction: The CPU continuously reads from and writes to primary memory, making it essential for the system’s performance. Unlike secondary memory, primary memory allows the CPU to retrieve data without delays.
Knowledge Booster:
· Register: Registers are small, fast memory locations within the CPU that hold immediate values for ongoing calculations. They are even faster than RAM but have limited storage capacity, meant only for active operations.
· Secondary Memory: Non-volatile storage like HDDs or SSDs, which retain data even after the system is powered off. The CPU does not access secondary memory directly, as it is used for long-term data storage.
· Cache Memory: Intermediate memory between the CPU and RAM that holds frequently accessed data. Cache speeds up processing by reducing the need for the CPU to repeatedly fetch data from primary memory.
