Parth Munjpara · Answer

=> Both processes and threads are independent sequences of execution. The typical difference is that threads (of the same process) run in a shared memory space while processes run in separate memory spaces. => Thread is the segment of a process means a process can have multiple threads and these multiple threads are contained within a process. => Process control block controls the operation of any process. Process control block contains the information about processes. => Process takes more time to terminate and it is isolated means it does not share memory with any other process.

1. Threads are easier to create than processes since they don't require a separate address space. 2. Multithreading requires careful programming since threads share data strucures that should only be modified by one thread at a time. Unlike threads processes don't share the same address space. 3. Threads are considered lightweight because they use far less resources than processes. 4. Processes are independent of each other. Threads since they share the same address space are interdependent so caution must be taken so that different threads don't step on each other. This is really another way of stating #2 above. 5. A process can consist of multiple threads.
