is a memory type with capacitors that need to be refreshed periodically.Select one:A.ROMB.DIMMC.DRAMD.SRAM

Step 1: Break Down the Problem

We need to identify which memory type among the options given requires periodic refreshing due to its reliance on capacitors.

Step 2: Relevant Concepts

• ROM (Read-Only Memory): This type of memory is non-volatile and does not require refreshing.
• DRAM (Dynamic Random Access Memory): This memory uses capacitors to store data, which need to be refreshed periodically to maintain data integrity.
• SRAM (Static Random Access Memory): This type does not require refreshing, as it uses bistable latching circuitry.
• DIMM (Dual In-line Memory Module): This is a form factor for RAM, usually containing either SRAM or DRAM.

Step 3: Analysis and Detail

From the analysis of each memory type:

1. ROM is not correct as it is non-volatile.
2. DRAM is correct because it uses capacitors that lose their charge and therefore must be refreshed at regular intervals (typically every few milliseconds).
3. SRAM does not require refreshing due to its design.
4. DIMM is a type of module that can contain various types of RAM, including DRAM.

Step 4: Verify and Summarize

The only memory type in the options requiring periodic refreshing due to its use of capacitors is DRAM. This periodic refresh is essential to ensure that the data stored in DRAM is not lost.

Final Answer

C. DRAM
