   Show answer

   Answer: (3) 1 and 3 only

   उत्तर: (3) केवल 1 और 3

   Cache memory is a small, very fast memory (usually SRAM) placed between the CPU and main memory to hold frequently used data and instructions, so 1 and 3 are correct. It costs more per byte than main memory (RAM), so "less expensive" in statement 2 is wrong.
