If you add SDRAM to your PC with a bus speed of 70 MHz
the bandwidth for the system will be 560MB per second.
If a program or files are actively being used or are open by the user, they are being used in system memory. T or F
True
If you add an odd number of RAM modules or you mismatch DIMM cards, there will be an error and the system might not work properly. T or F
True
The boot sequence is very important in the system setup. T or F
True
Symmetric multiprocessing (SMP) involves
a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single shared main memory.
Motherboards formerly used parity checking to detect errors. T or F
True
Graphic card memory (GDDR) is…
graphics memory that is dedicated to a discrete GPU and the workloads it operates on, separate from the system memory plugged in to your motherboard
