Explanation:

DRAM (Dynamic Random Access Memory) is the memory storage widely used in PCs and Embedded Systems.

Reasons for using DRAM:

1. High-density storage: DRAM is a high-density storage device, which means it can store a large amount of data in a small area. This makes it ideal for use in PCs and embedded systems where space is limited.

2. Fast access times: DRAM has very fast access times, which means that data can be read and written to it very quickly. This is important in applications where speed is critical, such as in gaming or video editing.

3. Low power consumption: DRAM is a low power consumption device, which means that it does not require a lot of power to operate. This is important in portable devices such as laptops and smartphones, where battery life is a critical factor.

4. Easy to interface: DRAM is easy to interface with other devices, which makes it ideal for use in embedded systems. It can be connected to microprocessors and other devices using standard interfaces such as SPI, I2C, and UART.

5. Cost-effective: DRAM is a cost-effective memory storage device, which means that it is relatively cheap to manufacture. This makes it a popular choice for use in PCs and embedded systems where cost is an important consideration.

Other Memory storages:

1. SRAM (Static Random Access Memory): SRAM is another type of memory storage device, which is commonly used in embedded systems. It is faster than DRAM and consumes less power, but it is also more expensive.

2. Flash memory: Flash memory is a non-volatile memory storage device, which means that it retains data even when power is removed. It is commonly used in portable devices such as USB drives and digital cameras.

3. EEPROM (Electrically Erasable Programmable Read-Only Memory): EEPROM is a non-volatile memory storage device, which can be erased and reprogrammed electrically. It is commonly used in embedded systems for storing configuration data and firmware.

Conclusion:

In summary, DRAM is the memory storage device widely used in PCs and embedded systems due to its high-density storage, fast access times, low power consumption, easy interfacing, and cost-effectiveness. Other memory storage devices such as SRAM, Flash memory, and EEPROM are also commonly used in embedded systems for specific applications.
