What three characteristics are true about SRAM and DRAM?
SRAM and DRAM both need to be refreshed with the same frequency
Both are considered volatile because they only hold data while power is on
SRAM is faster than DRAM because it does not need to be refreshed
DRAM is closer to the CPU than SRAM because it has a 64-bit data path
The type of memory used in a memory cache is SRAM because it is faster
An organization wants to increase the amount of RAM on their computers. All the computers have four memory slots but only two slots in each computer are populated. They want to add one more memory module to the older computers, and two additional modules to the newer computers. The older computers have three blue slots and one black slot. Which memory type will maximize the number of DIMMS the memory controller can access at the same time in both, the older and newer computers?
DDR
DDR2
DDR3
DDR4
A computer has four DDR4 memory modules. Two modules have a speed of 3000 MHz and the other two have a speed of 4000 MHz. If the two 3000 MHz DIMMs are upgraded, the new modules to be installed should have what rating?
PC4 24000
PC4 25600
PC4 28800
PC4 32000
