Please briefly explain how the Linux clone OS differs from UNIX processes and threads.

Linux clone system call is a mechanism that creates a new process or thread that shares some or all of its resources with the parent process. The clone call allows Linux to implement lightweight processes, or threads, which are similar to traditional UNIX processes and threads, but with some differences.

Here are some differences between Linux clone OS and UNIX processes and threads:

• Resource sharing: When a new process or thread is created using the clone call, the new entity shares some or all of its resources with the parent process. This includes the address space, file descriptors, and other resources. In contrast, traditional UNIX processes and threads have their own separate resources and do not share them with other processes or threads.

• Scheduling: In Linux, lightweight processes created using the clone system call share the same process ID (PID) as the parent process and are scheduled using the same scheduling algorithm as the parent process. In UNIX, processes and threads have their own unique PIDs and are scheduled using their own scheduling algorithms.
