Show answer & explanation
Correct answer: B
Statement (A) is wrong because RAM is volatile but ROM is non-volatile. Statement (B) is correct (ROM, PROM, EPROM are non-volatile). Statement (C) is wrong because RAM can be SRAM or DRAM; RAM and DRAM are not exactly the same. Statement (D) is correct because RAM is a read-write memory. Therefore, the wrong statements are (A) and (C).
