Quiz Questions & Answers

Question 1: In the video, which component is described as the 'brain' that makes decisions and performs math billions of times per second?
RAM (Random Access Memory)
GPU (Graphics Processing Unit)
Motherboard
CPU (Central Processing Unit)
Question 2: The video compares RAM to a desk and storage (SSD/HDD) to a filing cabinet. What practical consequence does this analogy highlight?
RAM and storage are interchangeable for running applications.
RAM is wiped when power is lost while storage keeps files after shutdown.
An HDD is always faster than an SSD for booting the OS.
RAM stores larger amounts of data more cheaply than hard drives.
Question 3: According to the lesson, why is the GPU described as a team of thousands of simple workers instead of a few smart ones?
Because GPUs run many parallel operations to color pixels simultaneously.
Because GPUs replace the need for a motherboard.
Because GPUs only handle audio processing in modern PCs.
Because GPUs are slower at math than CPUs and must split tasks.
Question 4: The video warns about 'bottlenecks' when building a PC. Which scenario best illustrates a bottleneck?
Adding more case fans to improve airflow in an already cool system.
Choosing a large case that fits all components comfortably.
Using an SSD for the OS and an HDD for large file storage.
A very fast CPU paired with a slow HDD so the system waits on file access.
Question 5: Which component does the video say you should never go cheap on because a failure could damage other parts?
Thermal paste
Case fans
Sound card
PSU (Power Supply Unit)
Question 6: If a user's PC is loud and slows down after a few years, what simple cause and remedy does the video recommend?
Upgrade the motherboard to the latest model to reduce noise.
Lower the RAM capacity because too much RAM causes loud fans.
Dust buildup causing heat; clean the dust to restore performance.
Replace the GPU immediately because noise always means GPU failure.
Question 7: Which two upgrades does the video suggest most often help a slow PC feel noticeably faster?
Install a liquid cooling loop and remove the GPU.
Replace the case and upgrade the sound card.
Add more RAM and switch from an HDD to an SSD.
Decrease the motherboard size and lower PSU wattage.
