Primary Memory
Secondary Memory

What is Primary Memory?
Primary Memory is the main memory of the computer system. Accessing data from primary memory is faster because it is an internal memory of the computer. The primary memory is most volatile, meaning data in primary memory does not exist if it is not saved when a power failure occurs.
The primary memory is a semiconductor memory. It is costlier compared with secondary memory. The capacity of primary memory is very much limited and is always smaller compares to secondary memory.

KEY DIFFERENCE
Primary memory is also called internal memory whereas Secondary memory is also known as a Backup memory or Auxiliary memory.
Primary memory can be accessed by the data bus whereas Secondary memory is accessed
