List reasons why a Mode switch between threads may be
cheaper than a Mode switch between processes?
Answer Posted / nirmalraj
Process :Generally heavy weight by, the PCB holds kernel
objects the values generally referred as state information.
A application can be divided into two types in design phase:
1.Process - may affect application/program architecture
2.Threads - didn't affect architecture
Threads typically are spawned for a short-term benefit where
as process for long-term even the thread share its own
process address space is never larger than 4GB.
A single process may hold "n" threads so exchanging value
between process; then the cpu spend most of its time for
swapping it leads to thrasing definitely.
Threads easily exchange their locale variables within its
scope but exchange value between process stolen more cpu cycles.
