Computation: Virtual thread and Goroutines Both Java virtual threads and Go goroutines are what we call user-space threads.

This means the language will manage and schedule workload, and context switch between OS threads for you. They are also more lightweight than Kernel threads because they have a smaller memory footprint, don’t need to involve OS calls, and have faster context-switch than Kernel threads.
