Dynamic Random Access Memory (DRAM)
DRAM stores date bits as electrical charge, these data bits are then stores on a bit cell which has a capacitor to hold the charge (1 represents data(charged) and 0 represents no data(not charged). The transistor help read the contents that are stored by the capacitor.
Since this type of RAM was new, the data that was stored slowly gotten weaker, meaning the memory loses its data.
DRAMS are packaged as SIMM (Single Inline Memory Modules), these modules has electrical contacts on both sides, acting as individuals. There was 2 versions of these - 8-bit(30-pins) and a 32-bit(72-pins)
Form Factors are the sizes and shape of something like Full Tower, Mid Tower and Mini Tower and so on... RAM are split into 3 form factors: DIMM, SODIMM and MicroDIMM

This is used for Desktop Computers
