(N/A) $1$. Both systems function by receiving, processing, and storing information from the environment or input devices.
$2$. They utilize electrical signals for transmission; neurons use action potentials, while computers use binary electronic pulses.
$3$. Both possess a memory storage mechanism: the brain uses synaptic plasticity and long-term potentiation, while computers use $RAM$ and hard drives.
$4$. Both systems operate based on logical decision-making processes to generate specific outputs or responses.
$5$. Both are highly complex networks where individual units (neurons or transistors) work together to perform sophisticated computational tasks.
