Research: RAM [Day 16]

Random-access memory, otherwise known as RAM, is the memory of the computer used to store data and be accessed directly in any order. Unlike other data storage media such as hard disks and DVD, they read and write data in a predetermined order. There are about 3 types of RAM which are dynamic RAM(DRAM), static RAM(SRAM), and phase-change memory(PRAM). DRAM is used in majority of computers and also has several types of it. There's single data rate(SDR) that's been used before 2002, and there's double data rate(DDR), DDR2, DDR3, where the larger the number, the faster it is to it's predecessor. Contents that are on RAM are the faster than any other type of information storage however the drawback of it is that it loses all of it when the PC is off.
