Correct Answer
dynamic
Dynamic
DYNAMIC
Explanation
DRAM stands for Dynamic Random Access Memory. It is a type of computer memory that stores each bit of data in a separate capacitor within an integrated circuit. The term "dynamic" refers to the fact that the capacitors need to be constantly refreshed in order to retain their data, unlike static RAM (SRAM) which does not require refreshing. Therefore, the correct answer is "dynamic" regardless of the capitalization.
15.
Memory in a memory cache is :
Correct Answer
D. SRAM
Explanation
SRAM stands for Static Random Access Memory, which is a type of memory commonly used in memory caches. Unlike DRAM (Dynamic Random Access Memory) which requires constant refreshing to retain data, SRAM retains data as long as power is supplied to it. It is faster and more expensive than DRAM, making it suitable for cache memory where speed is crucial. ECC RAM (Error-Correcting Code RAM) is a type of RAM that can detect and correct errors, but it is not specifically related to memory caches. SDRAM (Synchronous Dynamic Random Access Memory) is a type of DRAM that is synchronized with the system bus, but it is not specifically related to memory caches. Therefore, SRAM is the correct answer.
16.

Explanation
The correct answer is "You must read the motherboard specifications." This is because the ability to run ECC or non-ECC memory depends on the specific motherboard model. Some motherboards are designed to support ECC memory, while others may only support non-ECC memory. To determine which type of memory is compatible with a particular motherboard, it is necessary to refer to the motherboard specifications provided by the manufacturer.
26.
Can all motherboards run ECC or non-ECC memory?
Correct Answer
C. You must read the motherboard specifications.
Explanation
The correct answer is "You must read the motherboard specifications." This is because not all motherboards are capable of running both ECC and non-ECC memory. The compatibility of memory types depends on the specific motherboard model and its specifications. Therefore, it is necessary to refer to the motherboard specifications to determine whether it supports ECC or non-ECC memory.
27.
Which is faster - an ECC memory or non-ECC memory?
Correct Answer
B. Non-ECC memory
Explanation
Non-ECC memory is faster than ECC memory. ECC (Error Correcting Code) memory is designed to detect and correct errors in data, which adds an extra layer of processing and can slow down the memory's performance. On the other hand, non-ECC memory does not have this error correction capability, allowing it to operate at a faster speed. Therefore, non-ECC memory is the faster option compared to ECC memory.
28.
What type of error-checking do older SIMM's have?
Correct Answer
B. Parity
Explanation
Older SIMM's have parity error-checking. Parity error-checking is a method used to detect errors in data transmission. It involves adding an extra bit to each byte of data, which is used to check if the number of 1's in the byte is even or odd. If the number of 1's is odd, it means there is an error in the data. Parity error-checking is a basic form of error-checking and is less reliable compared to ECC (Error Correction Code), which can both detect and correct errors.
29.
A DIMM that has memory chips installed on both sides of the module is:
Correct Answer
B. Double sided
Explanation
A DIMM that has memory chips installed on both sides of the module is referred to as double sided. This means that the memory chips are present on both the front and back sides of the DIMM module. Dual ranked refers to the organization of memory chips on a DIMM, where each rank has its own set of memory chips. DDR2 is a type of memory technology and is not directly related to whether the DIMM is single or double sided.
30.
Mark the correct answers:
Correct Answer(s)
B. Single sided DIMMs are always single ranked.
C. Some double sided DIMMs are single ranked, meaning all chips on both sides of the DIMM are addressed at every read or write.
Explanation
Single sided DIMMs are always single ranked because they have memory chips on only one side of the module. Some double sided DIMMs are single ranked, meaning all chips on both sides of the DIMM are addressed at every read or write. This means that even though a DIMM is double sided, it can still function as a single ranked module if all the chips on both sides are accessed simultaneously. Dual and quad ranks, on the other hand, have superior performance compared to single ranked chips.
31.
Which of the following are true about DIMM channels?
Correct Answer(s)
B. A dual channel motherboard accesses two banks of memory at the same time.
C. Dual channels double the speed of memory access.
D. On a triple channel motherboard with 4 slot, if the memory is inserted in the 4th slot, triple channelling is disabled.
E. On a triple channel motherboard with 4 slots, if matching memory is inserted into the first two slots, and the 3rd and 4th slots, the memory controller will use dual channels.
32.
A DDR3 memory stick with a rating of PC3-16000 runs at _______ MHz. (numeric answer)
Correct Answer(s)
2000
Explanation
The rating PC3-16000 indicates that the DDR3 memory stick has a peak transfer rate of 16000 MB/s. Since 1 MB/s is equal to 1 million bytes per second, the rating can be converted to 16,000,000,000 bytes per second. To convert this to MHz, we divide by 8 (since there are 8 bits in a byte) to get 2,000,000,000. Therefore, the memory stick runs at 2000 MHz.
33.
DIMM's that provide 2 64 bit banks are called:
Correct Answer
B. Double sided
Explanation
DIMMs that provide 2 64-bit banks are called "double sided". This means that the memory module has memory chips on both sides of the module, allowing for a higher memory capacity. Each bank represents a separate set of memory chips, and having two banks doubles the data transfer rate and increases the overall memory capacity.
34.
Double sided DIMM's that provide two 64 bit banks are called:
Correct Answer
C. Dual ranked
Explanation
Dual ranked DIMMs are double sided DIMMs that provide two 64-bit banks. This means that they have two sets of memory modules on each side, allowing for increased memory capacity and performance. Dual ranked DIMMs are commonly used in servers and high-performance computing systems where large amounts of memory are required. Unlike single ranked DIMMs, which have only one 64-bit bank, dual ranked DIMMs provide better memory bandwidth and can handle more simultaneous data transfers.
35.
A double sided DIMM can be single ranked.
Correct Answer
A. True
Explanation
A double-sided DIMM refers to a type of memory module that has memory chips on both sides of the module. The term "single ranked" refers to the organization of the memory chips on the module. In this case, a double-sided DIMM can indeed be single ranked, meaning that all of the memory chips on the module are accessed in a single operation. This is in contrast to dual-ranked DIMMs, which have memory chips organized into two separate ranks.
36.
What is a memory bank?
Correct Answer
C. The memory a processor addresses at one time
Explanation
A memory bank refers to the portion of memory that a processor can access at any given time. It is not a physical stick of RAM or the slot where memory is inserted, but rather the specific portion of memory that the processor can interact with. This allows the processor to read or write data to and from that specific area of memory.
37.
Dual rankeed refers to the physical location of chips on a DIMM?
Correct Answer
B. False
Explanation
Dual ranked refers to the organization of memory chips on a DIMM, not their physical location. Dual ranked DIMMs have memory chips on both sides of the module, while single ranked DIMMs have chips on only one side. Physical location of the chips on a DIMM does not determine whether it is single ranked or dual ranked. Therefore, the given statement is false.
38.
Double sided refers to how the memory on the DIMM is addressed.
Correct Answer
B. False
Explanation
The statement is incorrect. "Double sided" does not refer to how the memory on the DIMM is addressed. It actually refers to the physical layout of the memory chips on the DIMM. A double-sided DIMM has memory chips on both sides of the module, while a single-sided DIMM has memory chips on only one side. The addressing of the memory on the DIMM is determined by the memory controller and the memory addressing scheme used by the system.
