1.) THE CONCEPTS OF PROCESS

A.) PROCESS STATE

-As a process executes, it changes state
new: The process is being created.F running: Instructions are being executed.
waiting: The process is waiting for some event to occur.
ready: The process is waiting to be assigned to a processor
terminated: The process has finished execution.

B.) PROCESS CONTROL BLACK

-Information associated with each process.
>Process ID
>Process state
>Program countern CPU registers
>CPU scheduling information
>Memory-management information
>Accounting information
>I/O status information

C.) THREADS

-Each process provides the resources needed to execute a program. A process has a virtual address space, executable code, open handles to system objects, a security context, a unique process identifier, environment variables, a priority class, minimum and maximum working set sizes, and at least one thread of execution. Each process is started with a single thread, often called the primary thread, but can create additional threads from any of its threads.
