Different Betweens in SRAM and DRAM ! Thank!

Explanation:

Application Differences:

SRAM

SRAM stands for Static Random Access Memory  DRAM stands for Dynamic Random Access Memory

Faster access is due to the usage of transistors to store single bit of data  

SRAMs are used for cache memories due to faster access time  

DRAM

DRAM stands for Dynamic Random Access Memory

DRAMs are used for main memories due to comparatively slower access time.

DRAMs use capacitor to store bits where each capacitor holds a single bit

Parameter differences  

Speed: SRAMs are faster due to presence of transistors. DRAMs are slower due to presence of capacitors

Size: Due to complexity involved in the internal circuits, SRAMs are smaller in capacity for same size of the chip. DRAMs are larger as compared to SRAMs since their capacity for a given physical size is more.

Cost: SRAMs are costlier and the per bit storage cost is more than that of the DRAMs. DRAMs are cheaper and the per bit storage cost is less than that of the SRAMs

Difference between SRAM and DRAM :

Sr.No.SRAMDRAM

1.Transistors are used to store information in SRAM.Capacitors are used to store data in DRAM.

2.Capacitors are not used hence no refreshing is required.To store information for a longer time, contents of the capacitor needs to be refreshed periodically.

3.SRAM is faster as compared to DRAM.DRAM provides slow access speeds.

4.These are expensive.These are cheaper.

5.SRAMs are low density devices.DRAMs are high density devices.

6.These are used in cache memories.These are used in main memories.

i will say b. laboratory technician   and if wrong then sorry

well you didnt give us any options it looks like so im going to go with because cash cant be traced.
