distinguish between dynamic ram and static ram

Dynamic RAM (DRAM) and Static RAM (SRAM) are two different types of computer memory that have distinct characteristics and functions.

1. Static RAM (SRAM):
- SRAM is faster and more expensive than DRAM.
- SRAM does not require refreshing, as it uses flip-flops to store data.
- SRAM is used in cache memory and as buffer memory in CPUs.
- SRAM is usually used for small amounts of fast cache memory.

2. Dynamic RAM (DRAM):
- DRAM is slower and cheaper than SRAM.
- DRAM requires refreshing in order to maintain the stored data, as it uses capacitors to store data.
- DRAM is used as the main memory in computers.
- DRAM is used for larger amounts of memory due to its lower cost per bit.

In summary, SRAM is faster but more expensive, used for small amounts of fast cache memory, while DRAM is slower but cheaper, used as the main memory in computers for larger amounts of memory.
