In Unix, a process is an independent entity that contains its own memory space, file descriptors, and resources. Each process has its own process ID (PID) and can execute code independently. On the other hand, a thread is a lightweight entity within a process that shares the process's memory space and resources. Threads share the same PID as the process they belong to and can execute code concurrently within the process.
