7.) DIFFERENCE OF RAM AND DRAM

-These terms all refer to different types of computer memory, or RAM - Random Access Memory. The "random" part means that any area of the memory can be communicated with. When people talk about how much memory or RAM their computer has, they are usually referring to DRAM (or in newer systems, SDRAM). (S)DRAM is a computer's main memory that holds onto information for the mictorprocessor. The "D" stands for dynamic, meaning the RAM needs to have the information it's holding continuously renewed or "refreshed". SDRAM (Synchronous DRAM) is a newer faster type of DRAM. Designed to keep up with today's high-speed microprocessors, SDRAM can typically run at the same speed as the overall system.
