What is the characteristic notch configuration of DDR RAM DIMMs?

Single Notch
Double Notch
No Notches
Triple Notch

The correct answer is: Single Notch

DDR RAM DIMMs typically have a single notch configuration. This means that there is only one keying notch, or groove, on the bottom edge of the RAM module. This design allows for easy installation and ensures that the DIMM can only be inserted in one direction into the motherboard. The other options are incorrect because - "Double Notch" is not the characteristic configuration of DDR RAM DIMMs. While some RAM may have two notches, this is not specific to DDR RAM and can vary depending on the type and manufacturer. - "No Notches" is also incorrect because all RAM modules have at least one notch, even if it is not visible or notched. - "Triple Notch" is not a common notch configuration for any type of RAM.
