Concept Check

0/5

What is the primary difference between goroutines and OS threads?

Goroutines are heavier than threads

Threads are managed by Go runtime

Goroutines are multiplexed onto threads

Goroutines require more memory

How does the Go scheduler handle goroutine blocking?

It runs other goroutines on the thread

Blocks all other goroutines

Switches to another thread

Pauses the entire program

What happens if a goroutine panics?

Panic propagates to main

All goroutines are terminated

Entire program crashes immediately

It terminates but program continues

Why are channels used with goroutines?

For safe communication and synchronization

To replace function calls

To increase goroutine speed

For direct memory access

What is a potential issue with shared memory in goroutines?

Data races and inconsistencies

Reduced memory usage

Increased execution speed

Automatic synchronization
