As the name indicates, DDR provides double data transmission in each clock cycle as compared to SDRAM. Read through this article to find out more about SDRAM and DDR and how they are different from each other. What is SDRAM? SDRAM ... Read More

Read through this article to find out more about normalization and denormalization and how they are different from each other. What is Normalization? Normalization is used to remove redundant data from the database and to store non-redundant and ... Read More
