What is the difference between a thread and a process?

1. process is the smallest unit of resource allocation, and thread is the smallest unit of resource scheduling.

2. The thread runs under the process. A process can contain multiple threads.

3. The process has its own independent address space. Every time a process is started, the system will allocate an address space for it. On the other hand, threads share data in the process and use the same address space.

4. Under the same process, the data between different threads is easy to share, while the data between different processes is difficult to share.
