PART 1 - RAM BASICS
1) WHEN WE USE THE TERM "RAM" WHEN DISCUSSING COMPUTERS, WHAT ARE WE REFERRING TO?
2) WHAT ARE THE TWO DIFFERENT TYPES OF RAM?
3) WHICH RAM IS SLOWER AND WHY?
4) IF RAM IS VOLATILE, WHAT DOES THAT MEAN?
5) WHAT GETS LOADED INTO RAM DURING USAGE?
6) WHAT IS ROM AND HOW IS IT DIFFERENT THAN RAM?
7) IS THIS STATEMENT TRUE OR FALSE?
THE MORE RAM IN A COMPUTER, THE MORE CAPACITY THE COMPUTER HAS TO HOLD AND PROCESS LARGE PROGRAMS AND FILES, AS WELL AS ENHANCE SYSTEM PERFORMANCE.
PART 2 - MEMORY MODULES
SIMM-SINGLE INLINE MEMORY MODULE
-30 OR 72 PIN SMALL CIRCUIT BOARD
DIMM

CACHE
-L1 - INTEGRATED INTO THE CENTRAL PROCESSING UNIT (CPU)
-L2 - ALSO INTEGRATED INTO THE CPU
-L3 - USED ON HIGH END WORKSTATIONS AND SERVERS
PART 3 - RAM TYPES
THE FOLLOWING PICTURE PROVIDES A VIEW OF SOME RAM TYPES:
SDRAM
SYNCHRONOUS DRAM. OPERATES IN "SYNC" WITH THE MEMORY BUS (PATH BETWEEN THE CPU AND THE MAIN MEMORY)
DDR SDRAM
DOUBLE DATA RATE SDRAM. TWICE AS FAST AS SDRAM.
DDR2 SDRAM
FASTER THAN DDR RAM. IMPROVES PERFORMANCE BY DECREASING NOISE AND CROSSTALK BETWEEN THE SIGNAL WIRES.
RDRAM
RAMBUS DRAM THAT WAS DEVELOPED TO COMMUNICATE AT VERY HIGH SPEEDS.
