A system call is needed for inter-process communication (IPC) between cooperating processes because it provides a controlled interface for processes to request services from the operating system. This ensures that communication is managed safely and efficiently, allowing processes to share data, synchronize their actions, and exchange messages without directly accessing each other’s memory. By using system calls, the operating system can enforce security, manage resources, and maintain stability in a multi-process environment.
The difference is that competing processes in an operating system compete for resources. Cooperating processes share resources, and some even work together to complete the same task.
a process which does not need any other external factor to trigger it is an independent process. a process which works on occurance of any event and the outcome effects any part of the rest of the system is called a cooperating process.

Adiabatic processes do not involve heat transfer between a system and its surroundings.
Endogenous processes are those that are internally driven by an organism, system, or entity, while exogenous processes are external factors that influence the system from outside. Processes that directly conflict with exogenous processes are typically those that originate within the system and contradict or resist the external influences. This can lead to a struggle for control or dominance between internal and external factors.

Multiprogramming typically requires at least one processor to manage multiple processes concurrently. However, the effectiveness of multiprogramming can be enhanced with multiple processors, as this allows for true parallel execution of processes. In a single-processor system, the CPU rapidly switches between processes to provide the illusion of concurrent execution, while in a multi-processor system, multiple processes can run simultaneously. Ultimately, the number of processors needed depends on the specific requirements and workload of the applications being executed.
System software provides the platform for application software.
The digestive system breaks down nutrients and allows them to be absorbed the the circulatory system, which carries them to all body cells. The circulatory system carries needed materials to the cells of the digestive system, so that they can carry out body processes.
