Which of the following is the memory cache on the processor chip?
- A.
Level 2 cache
- B.
Primary cache
- C.
DRAM
- D.
Secondary cache
Correct Answer
B. Primary cacheExplanation
The primary cache is the memory cache on the processor chip. It is the closest and fastest cache to the processor, providing quick access to frequently used instructions and data. It is also known as the level 1 cache and is smaller in size compared to the secondary cache.

A cooler is a combination of a cooling fan and which of the following?
- A.
Resistor
- B.
Housing
- C.
Heat sink
- D.
Riser card
Correct Answer
C. Heat sinkExplanation
A cooler is a combination of a cooling fan and a heat sink. A heat sink is a device that helps dissipate heat generated by electronic components, such as a CPU or GPU, by transferring it to the surrounding environment. It is typically made of metal with fins or ridges to increase its surface area for better heat dissipation. The cooling fan in the cooler helps to increase airflow over the heat sink, enhancing its cooling efficiency. Therefore, a heat sink is the correct answer as it is an essential component of a cooler.Rate this question:

True or False. Multiprocessing is accomplished when a processor contains more than one ALU.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Multiprocessing refers to the ability of a system to utilize multiple processors or cores to execute tasks simultaneously. Each processor typically contains an Arithmetic Logic Unit (ALU), which is responsible for performing arithmetic and logical operations. Therefore, if a processor contains more than one ALU, it means that it has multiple processors or cores, enabling multiprocessing. Hence, the statement is true.Rate this question:

True or False. Running a motherboard or processor at a lower speed than the manufacturer suggests is called overclocking.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Overclocking refers to running a motherboard or processor at a higher speed than the manufacturer suggests. Running them at a lower speed is not considered overclocking, but rather underclocking. Therefore, the given answer "False" is correct.Rate this question:

True or False. The front-side bus connects the processor to the internal memory cache.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The front-side bus does not connect the processor to the internal memory cache. The front-side bus is responsible for connecting the processor to other components such as the memory controller, expansion slots, and input/output devices. The connection between the processor and the internal memory cache is typically done through a dedicated cache bus or an integrated memory controller. Therefore, the correct answer is False.Rate this question:

- A.
Bus frequency
- B.
Processor frequency
- C.
Mph
- D.
Internalization
Correct Answer
B. Processor frequencyExplanation
The correct answer is "processor frequency" because it refers to the speed at which the processor performs its operations internally. This frequency is measured in hertz (Hz) and determines how quickly the processor can execute instructions and process data.Rate this question:

True or False.The method for improving performance that is based on the processor housing containing two processors that operate at the same frequency but independently of each other is called dual core processing.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The explanation for the given correct answer is that dual core processing refers to a method of improving performance by having two processors within the same housing. These processors operate at the same frequency but independently of each other. This allows for increased multitasking capabilities and improved overall performance.Rate this question:

Which of the following is NOT another name for the system bus?
- A.
Front-side bus
- B.
Motherboard bus
- C.
Back-side bus
- D.
External bus
Correct Answer
C. Back-side busExplanation
The back-side bus is not another name for the system bus. The system bus is responsible for connecting the CPU to the main memory and other components, while the back-side bus is a separate bus that connects the CPU to the cache memory. Therefore, the back-side bus is not synonymous with the system bus.Rate this question:

The processor frequency can be found by multiplying the system bus frequency by the ______________.
- A.
Multiplier
- B.
Data bus frequency
- C.
Processor speed
- D.
Bit size
Correct Answer
A. MultiplierExplanation
The processor frequency can be found by multiplying the system bus frequency by the multiplier. The multiplier is a value that determines the ratio between the system bus frequency and the processor frequency. By multiplying these two values, we can determine the actual speed at which the processor operates. The data bus frequency, processor speed, and bit size are not directly related to finding the processor frequency.Rate this question:

Which of the following is NOT another name for memory cache?
- A.
Static RAM
- B.
Dynamic RAM
- C.
L1, L2, and L3
- D.
SRAM
Correct Answer
B. Dynamic RAMExplanation
Dynamic RAM is not another name for memory cache. Memory cache is a small, fast storage component that stores frequently accessed data and instructions for quicker access by the CPU. Dynamic RAM (DRAM) is a type of main memory that requires constant refreshing to retain data, while memory cache is a separate component that stores data temporarily for faster access. Therefore, dynamic RAM is not a synonym for memory cache.Rate this question:

On-package L2 cache is located where?
- A.
Within the processor housing
- B.
On the motherboard
- C.
On front-side bus
- D.
On the DIMM
Correct Answer
A. Within the processor housingExplanation
The on-package L2 cache is located within the processor housing. This means that the cache is physically integrated into the processor itself rather than being located on the motherboard, front-side bus, or DIMM. Placing the cache within the processor housing allows for faster access to data as it is located closer to the processing cores, resulting in improved performance and efficiency.Rate this question:
