How is sound processed in a personal computer?
Sound functions in modern PCs will send your audio directly to an external radio for processing.
Sound functions must be provided by a plug-in sound card.
Sound functions are provided by a plug-in card with external speakers.
Sound functions are often provided by the motherboard chipset.
How would you access the system setup program on a PC?
Historically, by pressing and holding the Windows key (4 little white boxes) on your keyboard. Modern PCs use the function key "F5"
Historically, by pressing the appropriate key during startup (ESC, DEL, F1, F2, or F10). Modern PCs often use fast boot modes that require some other means of booting to the firmware setup program.
Logically, by pressing CTL+ALT+DEL twice during startup. Just like when you want to exit a program on your PC.
Logically, by pressing ALT+F4 during startup will access the startup menu through windows.
You want to purchase a computer with a fast graphics interface. What type of expansion slot should you look for?
Motherboard SIMM slots—this type of slot has 30-pin slots typically used in laptops while the 64-pin and 72-pin slots were found on desktop motherboards.
SDRAM and DDR—this type of slot is common for desktop computers (if you use a laptop, you need to look for a SODIMM) each having various types and speeds.
PCIe x16—this is a type of PCI Express slot that uses 16 'lanes'. Each lane can transfer 250 MBps (or 500 MBps for PCIe 2 and 1 GBps for v3).
Connect solid-state graphics to the high-speed SATA slots and mechanical disk drives to the lower-speed slots.
What type of component provides a passive cooling solution?
An insulation blanket
A cooling fan
A liquid cooling system
A heatsink
What is the main advantage of using a CPU in 64-bit mode?
It's new and technically more scalable than the 32-bit CPU.
CPUs don't use 64-bit mode; they are limited to 16 bits. This means that each instruction is 16-bits "wide".
There are no advantages of a 64-bit CPU over a 32-bit CPU. They cost more money and are not worth the cost.
A 64-bit CPU has the ability to use more system memory than a 32-bit CPU.
What is a typical speed for a mid-range CPU to run at?
Around 2 GHz; budget models might run as low as 1 GHz, while faster ones run at 3 or 4 GHz.
Around 2 MHz, if you overclock it. Most still run at 1 MHz.
Around 4 GHz for each core processor.
1.21 Gigawatts.
What computer component is most restrictive in terms of determining upgrade potential for a desktop computer?
System firmware
The Network Interface Card (NIC)
The motherboard
The Graphics Processing Unit (GPU)
What type of component provides persistent storage?
The Random Access Memory (RAM)
The Central Processing Unit (CPU)
The Hard Disk Drive (HDD) and Solid State Drive (SSD)
The Graphics Processing Unit (GPU)
What are the four things carried by a bus?
Data, Address information, Timing signal, Power
Data, Memory, Clock, Electricity
Data, Address information, Clock, Power
Data, Memory, Timing signal, Electricity
Which bus connects the CPU and system memory?
System bus
Expansion bus
Front Side Bus
Input/Output bus
Which version of PCIe doubles the bandwidth per lane?
All of them
PCIe 2.0

What is the bandwidth of PCIe 3.0 x16?
12 GBps
8 GBps
16 GBps
24 GBps
What is the function of the motherboard in a computer?

AMD
RISC
What does RISC stand for in microarchitectures?
Reduced Instruction Set Computing
Random Instruction Set Computing
Rapid Instruction Set Computing
Reliable Instruction Set Computing
What is the purpose of the Arithmetic Logic Unit (ALU) in a CPU?
Handles arithmetic and logic operations
Fetches the next instruction from system memory
Decodes each instruction and executes it
Writes the result of the executed instruction to a register or system memory
What is the function of the Control Unit in a CPU?
Fetches the next instruction from system memory
Handles arithmetic and logic operations
Writes the result of the executed instruction to a register or system memory
Decodes each instruction and executes it
What determines whether a CPU is 32-bit or 64-bit?
General Purpose (GP) register size
Clock speed
Bus speed
Number of cores
What is the clock speed of modern CPUs typically measured in?
Megahertz (MHz)
Gigahertz (GHz)
Kilohertz (kHz)
Terahertz (THz)
What is the difference between SMP and dual-core CPUs?
SMP involves physically installing multiple CPUs, while dual-core CPUs have two processors combined on the same die
SMP and dual-core CPUs are the same thing
SMP is only used in servers and high-end workstations, while dual-core CPUs are used in all types of computers
SMP and dual-core CPUs both use multiple processors, but SMP is more efficient
What is the purpose of registers in a CPU?
Temporary storage area available to different units within the CPU
Handles arithmetic and logic operations
Fetches the next instruction from system memory
Writes the result of the executed instruction to system memory
Which components in a computer are prone to thermal output issues?
