3.5 CQ B Flashcards
What does Hyper-Threading do?
A. It gives you multiple cores within the CPU.
B. It enables four simultaneous threads to be processed by one CPU core.
C. It enables two simultaneous threads to be processed by one CPU core.
D. It provides a high-speed connection from the CPU to RAM.
C. Hyper-Threading allows for an operating system to send two simultaneous threads to be processed by a single CPU core. The OS views the CPU core as two virtual processors. Multiple cores would imply multicore technology, which means there are two physical processing cores within the CPU package. Hyper-Transport is a high-speed connection used by AMD from the CPU to RAM.
What seals the tiny gaps between the CPU cap and the heat sink?
A. Grape jelly
B. Plumber’s putty
C. 3-in-1 house oil
D. Thermal compound
E. TDP
D. Thermal compound/thermal paste is used to seal the small gaps between the CPU and heat sink. It is sometimes referred to as thermal gel or jelly (among a variety of other names), but not grape jelly. (Did I ever tell you about the time I found grape jelly inside a customer’s computer? Fun times.) Note: Never use petroleum-based products (such as 3-in-1 oil or WD-40) inside a computer; the oils can damage the components over time. TDP stands for thermal design power.
Which of the following can be defined as the amount of heat generated by the CPU, which the cooling system is required to dissipate?
A. GPU
B. TDP
C. PSU
D. 140 watts
B. TDP (thermal design power) is the amount of power required to cool a computer and is linked directly to the amount of heat a CPU creates. Some CPUs come with a built-in graphics processing unit (GPU). This means that with a compatible motherboard, no separate video card is necessary. PSU stands for power supply unit. 140 watts is a potential TDP rating but does not define what TDP is.
When deciding on a CPU for use with a specific motherboard, what does it need to be compatible with?
A. Case
B. Socket
C. Wattage range
D. PCIe slots
B. The CPU needs to be compatible with the socket of the motherboard. The case doesn’t actually make much of a difference when it comes to the CPU. (Just make sure it’s large enough!) There is no wattage range, but you should be concerned with the voltage range of the CPU. PCI Express (PCIe) slots don’t actually play into this at all because there is no direct connectivity between the two.
Which kind of socket incorporates “lands” to ensure connectivity to a CPU?
A. PGA
B. Chipset
C. LGA
D. Copper
E. AM4
C. LGA (Land Grid Array) is the type of socket that uses “lands” to connect the socket to the CPU. PGA (Pin Grid Array) sockets have pinholes that make for connectivity to the CPU’s copper pins. AM4 is a PGA socket that accepts AMD CPUs such as the Ryzen 7.
Which of the following enables the user to increase the base clock within the BIOS, thereby increasing the clock speed of the CPU?
A. Overclocking
B. L3 cache
C. Integrated GPU
D. Heat sink
A. Overclocking enables the user to increase the clock speed of the CPU within the BIOS. Level 3 (L3) cache comes in the largest capacities of the three types of cache and has the most latency; therefore, it is the slowest. If the CPU can’t find what it needs in L1, it moves to L2 and finally to L3. An integrated GPU is a video adapter that is built into the motherboard. The heat sink helps to dissipate heat from the CPU and is usually aided by a fan or liquid cooling system.
