Which memory type is the silicon chip used to implement main memory?

• A. ROM (Read Only Memory)
• B. Cloud Storage
• C. RAM (Random Access Memory)
• D. Data

Answer: (C)

Main memory is the fast, temporary storage the CPU uses to hold data and instructions while a program runs. The silicon chip that implements this role is RAM because RAM is designed for rapid read and write access, letting the processor quickly fetch and update data as it works. ROM, by contrast, stores permanent firmware and isn’t meant to be written to during normal operation, so it isn’t main memory. Cloud storage sits outside the device and isn’t implemented on the computer’s memory chips, so it isn’t main memory. Data is just information, not a memory type. So RAM is the memory type that serves as main memory.
