What methods do processes interact with in the operating system?

Processes in the operating system interact with each other using various inter-process communication (IPC) methods:

• Pipes — allow sequential data transfer between processes, usually related.
• Sockets — enable data exchange between processes, both on the same computer and over a network.
• Shared memory — allocates a memory area accessible by multiple processes for fast data transfer.
• Semaphores — used for synchronizing access to shared resources.
• Message queues — allow processes to exchange structured messages.

In Go, channels are commonly used for interaction between goroutines, providing safe data transfer and synchronization.

Example of using a channel in Go:

ch := make(chan string)
go func() {
    ch <- "Hello from goroutine"
}()
msg := <-ch
fmt.Println(msg)
