Q#1

Only the shared memory segments are shared between the
parent process and the newly forked child process. Copies of the stack
and the heap are made for the newly created process

Q#1

The parent and child share only the shared memory segments. Everything else is duplicated, but
the child has its own versions (changes it makes won’t be visible to the parent, and vice-versa

Q2

The CPU current-register-set pointer is changed to point to the

set containing the new context,which takes very little time. If the context

is in memory, one of the contexts in a register set must be chosen and be

moved to memory, and the new context must be loaded from memory  into the set. This process takes a little more time than on systems with one set of registers, depending on how a replacement victim is selected.
