- A process is a program in execution.
- Every process has its own address space.
- A process refers to the concurrently running entity on the system with tight protection.
- processes interact only through system-provided inter-process communication mechanisms.
- processes are typically independent.
- A thread is just an independent execution (trace) through the code of a process.
- In order to create threads, first you need a virtual address space, which is instantiated when the process is created.
- Threads are also called as light weight process ( because they don’t need separate resource allocation ) .
- Threads have full access to utilize it’s parent process resources (also termed as loose protection).
- Threads refers to the concurrently running entity within the process.
- Threads uses address spaces of the process.
- A task refers to the concurrently running entity on the system with loose protection.
- A task is simply a set of instructions loaded into the memory.
- A task needs a thread to execute.
- A specific instance of executable code and its data environment.
