Consider the following statements and choose the correct combination:Main memory is typically volatile and loses its contents when the power is turned off.The size of the main memory is smaller than that of cache memory.DRAM (Dynamic Random-Access Memory) requires periodic refreshing to maintain data integrity.Accessing data from main memory is slower than accessing data from registers.ROM (Read-Only Memory) is commonly used as a temporary storage location for running applications.Memory hierarchy is organized based on access time, with the slowest memory closest to the CPU.
Question
Consider the following statements and choose the correct combination:Main memory is typically volatile and loses its contents when the power is turned off.The size of the main memory is smaller than that of cache memory.DRAM (Dynamic Random-Access Memory) requires periodic refreshing to maintain data integrity.Accessing data from main memory is slower than accessing data from registers.ROM (Read-Only Memory) is commonly used as a temporary storage location for running applications.Memory hierarchy is organized based on access time, with the slowest memory closest to the CPU.
Solution
The correct combination of statements is:
- Main memory is typically volatile and loses its contents when the power is turned off.
- DRAM (Dynamic Random-Access Memory) requires periodic refreshing to maintain data integrity.
- Accessing data from main memory is slower than accessing data from registers.
- Memory hierarchy is organized based on access time, with the slowest memory closest to the CPU.
The incorrect statements are:
- The size of the main memory is smaller than that of cache memory. This is incorrect because the size of the main memory is typically larger than that of cache memory.
- ROM (Read-Only Memory) is commonly used as a temporary storage location for running applications. This is incorrect because ROM is non-volatile memory used to store firmware or software that boots up the computer and performs diagnostics. It is not used as a temporary storage location for running applications.
