What is an advantage of using double-sided memory over single-sided memory?

What is an advantage of using double-sided memory over single-sided memory?

a 64 bit OS can run on

both a 32 bit and 64 bit CPU

include specialized chips that act as buffers for signals from the memory controller. By buffering these signals, the electrical load placed on the controller is reduced because the memory controller communicates in series with the register, instead of in parallel with the memory chips. The register performs the parallel communication with the chips.

buffer memory modules

allows for the CPU to set aside an area of memory and refuse to execute any code placed into that memory location. Oftentimes this serves as a buffer area. The result is that malicious buffer overrun attacks are less likely to succeed.

executable disable bit (EDB)

The set of signal pathways on a motherboard between the CPU and RAM is called what?

frontside bus (FSB)

What is the function of the laser in a laser printer?

it creates an image of the paper on the drum
