Little History about RAM The very first RAM came into existence in the year 1947 with the use of williams tube. It make use of  CRT( Cathode Ray tube), that are used as the faces of  electrically charged spots. The another type of RAM is magnetic-core RAM which was also developed in the year 1947. RAM is the main component into the computer system which play very important role.       Types of RAM There are mainly five types of ram;- Static RAM (SRAM) Dynamic RAM (DRAM) Synchronous Dynamic RAM (SDRAM) Single Data Rate Synchronous Dynamic RAM (SDR SDRAM) Double Data Rate Synchronous Dynamic RAM (DDR SDRAM, DDR2, DDR3, DDR4) Use of RAM Its a type of volatile memory which is used by a system temporarily. If computer shuts down abruptly then the data stored in it is erased. What is DDR? It stands for Double Data Rate. Its an advancement in SDRAM( Synchronous Dynamic Random Access Memory). Its a type ...
