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
Tomi buys a CPU from a computer store. The retail box references the amount of L1 cache in the list of features. What is it referring to?
The maximum amount of memory the processor can access
The memory in the CPU package, but not on the processor die
The amount of memory residing directly on the processor die
The memory between the CPU package and the DIMM slots
A system administrator boots a Windows PC using a Live Linux CD/DVD and list the files on the system. One of the files is called pagefile.sys. What is this file used for? Select all that apply.
Windows normally stores virtual memory in this file.
Windows stores filesystem information in this file.
Used to enhance the amount of RAM in the system
It is a type of cache to backup up the contents of UEFI
Mirrors the contents of RAM to improve performance.
A field service technician is replacing a server motherboard that supports CPUs with multithreading capabilities. The technician notices the motherboard has four processor sockets. If each socket supports a quad-core processor, how many logical processors does the system appear to have?
4

For maximum efficiency and performance, a highly tuned and specialized application needs to run on a system capable of handling exactly 16 threads at the same time from the operating system. Which two of the following will best meet the specified requirement?
A motherboard with four dual-core processors
A system board with two quad-core processors
A system with a 64-bit operating system installed
A system board with four quad-core processors
A motherboard with two 8-core processors
Jenny is working on a laptop computer and notices that the computer is not running very fast. She looks and realizes that the laptop supports 8GB of RAM and that the computer is running only 4GB of RAM. Jenny would like to add four more gigabits of RAM. She opens the computer and finds that there is an open slot for RAM. She checks the other module and determines that the module has 204 pins.
What module should Jenny order?
SO-DIMM DDR
SO-DIMM DDR2
SO-DIMM DDR3
SO-DIMM DDR4
You are researching RAM for a computer you are building for a friend who will be using the system as a home office server for a small business. She wants the added protection so the computer will not crash due to a memory error.
What type of RAM should you consider purchasing?
Unbuffered
Buffered
ECC
Registered
You are reviewing new RAM to purchase for a gaming computer and find three different RAM modules that are the same except for their CL rating.
The memory with which rating will work best?
CL15
CL18
CL20
They will all perform at the same speed.
Yesterday you installed a new game on your computer. When you ran the computer, you noticed that the application was running very slow. After you exited the game and restarted it (the game), you received an error message saying, "Insufficient memory or disk space." You checked the hard drive, and it has more than 250GB of free space.
What should you check next in Task Manager?
Amount of RAM available.
Amount of processor being used.
Amount of disk space being used by the application.
Programs that are running.
Gina is upgrading your computer with a new processor. She installs the processor into your motherboard and adds the cooling system. She powers up the computer, and it begins to boot but then shuts down.
What could be the cause of this problem?
Computer is overclocked.
Thermal compound was not used.
Processor is not compatible.
Processor is not seated properly.
After installing the processor and reassembling the computer, the system begins the boot process and suddenly turns off before completing the boot. You turn everything off, unplug the power cord, press the power button to drain the power, and open the case. What should you do next?
Verify the processor is securely seated and connected
Verify the cooler is securely seated and connected
Rotate the processor clockwise 90 degrees in the socket
Remove the old power supply and install a new one
When selecting a processor to match system needs, what features should you NOT consider?
Reviews of processors, including benchmarks and comparisons to other processors
Processor's ability to multitask, the number of cores, and multithreading abilities and which programs can make use of the abilities
Balancing the performance and power of the CPU with the entire system, including graphics adaptors and hard drives
The latest and most powerful processor available because the performance benefit will far outweigh the cost
. An entrepreneur wants to design and produce memory modules that meet industry specifications. To increase memory performance in servers the module should use technology to hold and amplify the signal just before the data is written to the module. What technology should the memory modules include?
ECC
Registers
Parity
CAS
