Computer Cases
What is the primary purpose of a computer case?
To protect the internal hardware components from dust, physical damage, and electrical interference, while holding them securely in place.
In what unit of measurement is modern CPU clock speed typically expressed, representing billions of cycles per second?
Gigahertz
What is the main purpose of processor cooling?
To remove heat from the CPU and prevent overheating.
What are the four fundamental steps that make up a single machine cycle?
Fetch, Decode, Execute, and Store.
What are registers
Extremely small, ultra-fast temporary storage locations located directly inside the CPU.
What common tower case size is designed to accommodate standard ATX motherboards and offers a good balance of expansion space and desk footprint?
Mid-Tower.
What physical component on the motherboard generates the continuous electrical pulses used to synchronize the computer's operations
A quartz crystal oscillator
What is the name of the paste applied directly between the CPU integrated heat spreader (IHS) and the cooler base to eliminate microscopic air gaps?
Thermal paste
During which phase of the machine cycle does the Control Unit translate an instruction into commands the CPU circuitry can understand?
The Decode phase.
Which specific register acts as a counter that holds the memory address of the next instruction waiting to be fetched and executed?
The Program Counter
This standardized specification dictated by motherboard sizes ensures that mounting holes, power supplies, and rear ports line up correctly inside a case. What is it called?
Form factor
What is the term for forcing a processor to run at a higher clock speed than it was rated for by the manufacturer?
Overclocking
What passive cooling component features a block of metal with many thin fins designed to maximize surface area contact with the air?
A heatsink
Where does the CPU fetch its next instruction from during the first step of the machine cycle?
Primary storage or System Memory
When an instruction is fetched from memory, what register holds that instruction while it is being decoded by the control unit?
The Instruction Register
In computer case design, what does "positive air pressure" mean?
It means there is more air being drawn into the case by intake fans than is being pushed out by exhaust fans, which helps prevent dust from entering through un-filtered gaps.
If a processor completes one operation every single clock cycle, how many operations can a 3.5 GHz processor theoretically perform in one second?
3.5 billion operations.
Liquid cooling systems use a component consisting of hollow copper tubes filled with a liquid that evaporates at the CPU side and condenses at the fin side. What are these tubes called?
Heat pipes.
Which specific hardware component inside the CPU core is responsible for handling the mathematical calculations and logical comparisons during the "Execute" phase?
The Arithmetic Logic Unit
What is the name of the primary register used by the Arithmetic Logic Unit to temporarily hold the immediate results of mathematical operations?
The Accumulator
Open-air cases and test benches lack protective outer panels entirely. What is the main structural disadvantage regarding airflow when using this style of case?
It eliminates directional airflow, meaning there is no channeled wind tunnel effect to passively cool secondary components like VRMs or storage drives without dedicated local fans.
What is the difference between the system clock and the Real-Time Clock (RTC)?
The system clock synchronizes internal CPU operations and runs at billions of cycles per second, while the Real-Time Clock keeps track of the actual human date and time and runs continuously even when the PC is powered off.
What safety mechanism triggers automatically inside a modern CPU to lower its clock speed and voltage when it detects it has reached dangerous operational temperatures?
Thermal throttling.
What optimization technique allows a modern CPU to process multiple machine cycles simultaneously by working on the "Fetch" step of a new instruction while an older instruction is in the "Decode" or "Execute" step?
Pipelining.
What is the difference between an internal/special-purpose register and a General-Purpose Register
Internal registers have strict, dedicated hardware functions required to run the CPU, whereas General-Purpose Registers can be directly manipulated by programmers and software compilers to store any temporary data or variables.
