Threads always share common data and context switching between threads is faster thats why there is no protection.

Bro, there is no need for protection in the case when we are implementing thread at the user level because within the same task we will have more threads. can u imagine there is no problem of the critical section over here, we will always write the code in such a way that will not create any problem

What about the first point, well there is no need of IPC between threads of same process as they all share the same address space hence its faster then IPC of Processes right ?

Answer 1

S1 is false as context switching in threads is faster

s2 is true .
