PROCESS VS THREADS

Some points of differences between process and thread are as follows:

[1]  Threads cannot live on its own, it must live within a process while process cam live on its own. Process has its own input, resources etc.

[2]   There can be more than one thread in a process but there it is not possible to have two process in a single thread.

[3]   The thread creation is inexpensive because OS  does not involve while the process creation is expensive .

[4]   Threads minimize the context switching while the process has expensive context switching.

[5]   If a thread in a process dies, another thread in a thread stack can run. but if a process dies, its resources are de-allocated and all its thread dies.

[6]  Process has separate address space where as thread share the address space.

[7]  Threads are easier to create because they don’t require separate address space where as process are complex to create because it requires separate address space.

[8]  Threads are considered light weight because they uses less resources then processes.
