System Unit Explained - Random Access Memory (RAM)
The Random Access Memory or RAM acts as temporary storage as long as the computer is running. The contents of the RAM change as programs are executed. RAM gives applications a place to store and access data on a short-term basis. It stores the information your computer is actively using so that it can be accessed quickly. Unlike HDD or SDD's, the memory in RAM is erased once the computer is turned off. 3 Basic Types of RAM Dynamic RAM (DRAM) – This kind of RAM needs to be recharged by the CPU. If not, it loses its contents. There are many variations of DRAM such as: Synchronous DRAM (SDRAM) – faster than DRAM because it is synchronized to the system clock Double Data Rate (DDR) SDRAM – faster than SDRAM because they transfer data twice for each clock cycle DDR2 and DDR3 SDRAM – faster than DDR SDRAM Rambus DRAM (RDRAM) – type of DRAM faster than SDRAM that uses pipelining techniques Static RAM (SRAM) – This kind is faste
