Как differs the behavior of threads during network requests compared to file reading operations?

In Go, the behavior of goroutines during network requests and file reading differs mainly due to the nature of operations and blocking. Network requests are typically asynchronous and non-blocking at the OS level, so a goroutine performing a network call can be paused, and the Go scheduler switches to another goroutine. This allows efficient resource utilization and handling multiple network connections simultaneously. File reading, especially from local disks, is often blocking at the OS level. However, the Go standard library implements file reading using system calls that can block the thread. Nonetheless, the Go scheduler tries to minimize the impact of blocking by switching goroutines and using a thread pool. Therefore, network goroutines usually do not block the system thread, but file reading may cause blocking, affecting performance and requiring careful concurrency management.
