Answer 1

The correct answer is DRAM.

Key Points

DRAM:
- It is dynamic random access memory and is widely used as a computer's main memory. Hence, Option 2 is correct.
- Each DRAM memory cell is made up of a transistor and a capacitor within an integrated circuit, and a data bit is stored in the capacitor.
DDR-RAM:
- It stands for Double Data Rate Synchronous Dynamic Random-Access Memory.
- These are the computer memory that transfers the data twice as fast as regular chips like SDRAM chips because DDR memory can send and receive signals twice per clock cycle as a comparison.
SRAM:
- It stands for Static Random Access Memory.
- It is a form of a semiconductor.
- It is widely used in microprocessors, general computing applications, and electronic devices.
- The SRAM is volatile in nature which means the data stored in it gets all wiped out once the power supply is cut.
- SRAM is comprised of flip-flops.
PRAM:
- In computer science, a parallel random-access machine is a shared-memory abstract machine.
- As its name indicates, the PRAM is intended as the parallel-computing analogy to the random-access machine.
