Mati ur rehman's roll number is 35 and subject is Operating system. A process includes program code and state and can consist of multiple threads. Processes can pass information to each other and have states like created, waiting, running, and terminated. Threads are independent sequences of instructions created by a process that share the process's resources, making passing information between threads easier than between processes.

Subject: Operating system

2.  How one process can pass information to other

3.  A process is a running program.
 A process includes the program code and its
state.
 A single process consists of one or more thread.
 Multitasking , A single CPU can run multiple
processes at same time.

4. CREATED WAITING
RUNNING TERMINATED

5. Created:
The process state be created
which mean that is the loaded from
disk to main memory.
Waiting:
The process waiting for the
O.S schedulor software to load.the
process to at processor.

6. Running:
That the processor executing
the process instruction.
Terminated:
That the processes
complete in ready to be on
loaded from the main memory

7.  A thread is an independent sequence of
instruction.
 A thread is created by a process.
 A thread is a subset of the process.
 Multiple thread share the process instruction
process variable & process state.

8. Passing information is easy for threads
since they share a common address space
(threads in different address spaces that
need to communicate fail under the
heading of communicating processes).
