Biomimicry

What inspired the Tokyo rail system optimization experiment?

• Artificial intelligence

• A slime mold called Physarum polycephalum

• A robot mapping program

• A train simulation software

What is biomimicry?

• Programming nature using AI

• Using biology to solve coding errors

• Mimicking natural systems to design better technologies

• Turning biological organisms into machines

Which of these is NOT a behavior of slime mold?

• Reinforcing food paths

• Growing toward food

• Solving mazes

• Sending error messages to the CPU

Why is the simple sequential model considered inefficient in modern CPUs?

• It’s too complicated

• It wastes electricity

• It executes only one instruction at a time, underusing CPU resource

• It doesn’t support binary code

What is the main reason CPUs use pipelining?

• To make the CPU smaller

• To reduce power consumption

• To execute multiple instructions at different stages simultaneously

• store instructions in memory

What does branch prediction help avoid?

• Slime mold errors

• Slow RAM access

• Power surges

• Delays caused by decision-making in code

How does cache optimization help a CPU?

• It avoids overheating

• It predicts program output

• It keeps frequently used data close for faster access

• It stores backup instructions in case of failure

Which of the following best describes parallel processing?

• Multiple cores running multiple tasks simultaneously

• One task done in sequential stages

• One core running multiple programs at once

• A process that only works on GPUs

Which CPU concept is most similar to how slime mold reinforces efficient paths?

• Pipelining

• Branch prediction

• Cache optimization

• Instruction decoding

What does the "Fetch" stage in pipelining do?

• It executes the instruction

• It writes the result

• It retrieves the instruction from memory

• It decodes the instruction
