  • Define and describe RAM
    Random Access Memory, is volatile memory where information is not permanently saved, used to hold information relevant to real-time processes
  • Define and describe DIMM
    Dual Inline Memory Module, the module of RAM with a 64 bit data width
  • Define and describe SODIMM
    Small Outline DIMM, a smaller form factor of RAM used primarily in mobile devices
  • Define and describe DRAM
    Dynamic RAM, is the memory on a DIMM, it is refreshed constantly otherwise the stored data vanishes
  • Define and describe SDRAM
    Synchronous DRAM, is RAM that is synchronous with the system clock so that it can queue processes
  • Define and describe SDR and DDR
    Single Data Rate and Double Data Rate, are standards for the data speeds of RAM with DDR being twice as fast
  • How does DDR achieve higher speeds than SDR?
    DDR is able to process 2 datasets within a single clock cycle
  • What is the maximum size per DIMM of DDR3?
    16GB
  • What is the maximum size per DIMM of DDR4?
    64GB
  • What is the maximum size per DIMM of DDR5?
    64GB
  • True or False: DDR generations are backwards compatible
    False - The key location moves between generations and motherboards are designed for a single transfer speed
  • Define and describe VRAM
    Virtual RAM, is a technology that allows swapping of unused application data to storage to free up additional memory space
  • What is Multi-Channel Memory?
    Using multiple RAM slots to decrease the workload on individual DIMMs
  • Define and describe ECC Memory
    Error Correcting Code Memory, is a RAM type that reserves space for error checking and correction, some RAM uses parity to reduced effect
