How operating system work?
The operating system acts as an interface between an application and the hardware. The user interacts with the hardware from "the other side". The operating system is a set of services which simplifies development of applications. Executing a program involves the creation of a process by the operating system. The kernel creates a process by assigning memory and other resources, establishing a priority for the process (in multi-tasking systems), loading program code into memory, and executing the program. The program then interacts with the user and/or other devices performing its intended function.

Is operating system a program?
yes, operating system is a program
How does the concept of process and program apply in single tasking systems as opposed to multitasking systems?
A program is a passive entity as opposed to process which is an active entity.essentially program just constitues the disk/memory image of a process in any operating system. This distinction is very important for multitasking operating systes. However in case of Serial Operating systems the scenario is quit diffrent. As you might know that many devices within the systems generate intterupts and when an inturrpt occurs the processor suspends the execution of currently executing task , saves its state and executes some another Interrupt Handler e.k.a a another process. This is exactly the same feature that is exploited by Multi Tasking operating systems to pre-empt a process after its time quantum has expired. So even in serial/sequential operating systems such as DOS etc the distincition of process and program is important because you can only associate execution context with a process not a program. One scenario that i can think of where process & program means one and the same thing to an OS are the Old Batch Operating Systems. There once a job(program) was submitted the control of entire machine goes in the hand of the job(process). There the OS does not /cannot diffrentiate between a process and program. The submitted job does all the necessary scheduling / interrupt control with in itself. Also older batch operating systems ran on hardware that sometime had no notion of Interrupts. I hope that might help you, Thanks
What are process states in operating system?
To put it in simple terms, we write our computer programs in a text file and when we execute this program, it becomes a process which performs all the tasks mentioned in the program. When a program is loaded into the memory and it becomes a process, it can be divided into four sections ─ stack, heap, text and data
What is pseudo-parallelism in context process implementation?
At a particular time either a user program is running or operating system is running.
what is operating system signal?
Signal is a way of communication between process and OS kernel. If process (running program) undergoes any serious issue, then kernel generates signal .

What word describes the process by which humans allow certain organism to mate in order to pass along desirable traits?
A breading program.
What does a computer process contains?
Processes are an operating system concept used to allow multiple programs to appear to run simultaneously on one computer. The operating system allocates at least one process to every program and switches periodically from running one process to another process.As a process is a concept, not a physical object, it does not actually contain anything.
