RAM (Random Access Memory), "The Brain of Your Computer"

RAM (Random Access Memory) is used for temporary storage in computers. By this we can access and transfer data faster. This is a volatile type of memory. There are two types of RAM known as SRAM (Static Random Access Memory) and DRAM (Dynamic Random Access Memory).  The packing density of DRAM's is high because in DRAM data is stored by small capacitors, these capacitors slowly discharge energy so we need to refresh these capacitors periodically and need extra circuitry for this purpose. But in SRAM refreshing is not necessary. Both are listed as volatile memory in which data is lost with power off of computer.

SDRAM (Synchronous Random Access Memory) is a solid-state computer memory. It based completely on semiconductors, transistors and chips. SDRAM reacts as quickly as possible with the change of input. For Example, during one site is loading on our computer we typed a new address on web browser and press enter. SDRAM stops loading initial site and starts loading the newer one as quickly as it can, this process is known as pipelining. SDRAM is directly connected to computer processor so it can react so quickly with respect to change of inputs.

The delay between the times when the data requested and the data shown is known as latency. The pipelining allows for a certain time amount to pass before requested data is displayed. The cause of this latency is computer's central processing unit (CPU), which is faster than SDRAM that’s why computer is waits for SDRAM to catch up before it continues. While choosing SDRAM one should be keep in mind the latency factor, as it is one of the most important factor.
