<human>:  What's the difference between a process and a thread?
<bot>: The main difference between a process and a thread is that a process is a program in execution, while a thread is an entity within a process that can independently execute instructions. A thread is a subset of a process and is used to achieve multitasking within a process. A process is an isolated environment that tells the operating system to allocate resources, while a thread is a separate path of execution within a process. A process is generally a larger unit of work compared to a thread.
