5 Questions
What is the difference between volatile and non-volatile memory?
Volatile memory loses its content when the power is lost, while non-volatile memory retains its content even if the power is lost.
Give an example of a primary memory.
RAM (Random Access Memory)
What is the meaning of NVRAM?
NVRAM stands for Non-Volatile Random Access Memory.
Explain the meaning of Static RAM (SRAM).
Static RAM retains its content as long as power is being supplied but loses data when the power is lost.
What is the purpose of secondary memory?
Secondary memory is used for permanent storage of data, unlike primary memory which stores data temporarily.
Study Notes
Memory Types
- Volatile Memory: Loses its stored data when the power is turned off.
- Non-Volatile Memory: Retains its stored data even when the power is turned off.
Primary Memory
- Example: Random Access Memory (RAM) is a primary memory that temporarily stores data and applications while a computer is running.
NVRAM
- Non-Volatile Random Access Memory: A type of memory that combines the benefits of RAM and ROM, allowing data to be written and erased repeatedly while retaining its data even when power is turned off.
Static RAM (SRAM)
- Definition: A type of RAM that stores data in a static form, using a flip-flop circuit to store each bit, making it faster and more reliable than other types of RAM.
Secondary Memory
- Purpose: Provides long-term storage for data and programs, even when the power is turned off, serving as a backup to primary memory and allowing data to be retrieved when needed.
