Chapter 5 Test - Processors And Chipsets

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.

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.

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.

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.

The three basic components of a processor are the I/O unit, control unit, and arithmetic logic unit. The I/O unit is responsible for input and output operations, the control unit manages and coordinates the activities of the processor, and the arithmetic logic unit performs arithmetic and logical operations on data. These three components work together to execute instructions and process data within a computer system.

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.

The cache on the motherboard is called L3. The L3 cache is an additional cache that is separate from the L1 and L2 caches found within the processor housing. It provides a larger storage capacity and helps improve the overall performance of the system by reducing the time it takes to access data from the main memory.

The speed at which data is placed on the bus refers to the bus frequency. This term indicates how quickly information is transferred between the different components of a computer system through the bus. It is an important factor in determining the overall performance and efficiency of the system.

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.

The correct answer is South Bridge. The South Bridge is responsible for connecting all I/O devices, except for the display and memory, to the hub. It acts as a bridge between the CPU and the I/O devices, facilitating communication and data transfer between them. The South Bridge handles functions such as USB, SATA, audio, and Ethernet connectivity, making it an essential component in the overall system architecture.

The Celeron processor is a low-end Pentium processor that targets the low-end PC multimedia and home market segments. It is designed to provide basic performance for everyday tasks such as web browsing, word processing, and multimedia playback, making it suitable for budget-conscious consumers who do not require high-end computing power.

A PGA socket is a type of socket used for connecting a processor to a motherboard. In a PGA socket, the pins of the processor are aligned in uniform rows around the socket. This design allows for easy installation and removal of the processor, as well as efficient electrical connections between the processor and the motherboard. The other options mentioned, such as using lands or having staggered pins, do not accurately describe a PGA socket.

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. The primary cache helps in reducing the latency of memory access, improving overall system performance.

The term "word size" refers to the largest number of bits that a processor can process in one operation. It determines the maximum amount of data that the processor can handle at a time, which directly affects the efficiency and speed of the processor. A larger word size allows for more data to be processed simultaneously, resulting in faster and more efficient operations.

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.

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.

The processor's housing is commonly referred to as a "package". This term is used to describe the protective casing that contains the processor and helps to dissipate heat generated during operation. The package is designed to provide physical protection to the delicate components inside and also acts as a medium for transferring heat away from the processor.

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.

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.

The correct answer is DIP. The question is asking about the type of socket used for earlier micro-processors, which were rectangular with two rows of pins down each side. DIP stands for Dual In-line Package, which is a common type of socket used for integrated circuits, including micro-processors.
