How does process communicate with each other?

Processes can communicate with each other through both:

Shared Memory.
Message passing.

Why inter process communication is needed?

Inter process communication (IPC) is used for exchanging data between multiple threads in one or more processes or programs. Since every single user request may result in multiple processes running in the operating system, the process may require to communicate with each other.

What is indirect communication in operating system?

Indirect Communication: In this case, each pair of processes wants to communicate with each other needs to have a shared mailbox. The sender places the message in the mailbox also known as a port and the receiver removes the data or message from the box.

What is interprocess communication in operating system?

Interprocess communication is the mechanism provided by the operating system that allows processes to communicate with each other. This communication could involve a process letting another process know that some event has occurred or the transferring of data from one process to another.

What are the advantages of indirect communication?

Indirect communication allows you to edit and adjust your message as you go. This may naturally prevent missteps, conflicts, and even cultural miscommunications. Indirect communication will force you to become a better listener, to pay attention, to read body language, and look for nonverbal indicators.

Can a link be associated with more than two processes?

How are links established? Can a link be associated with more than two processes? How many links can there be between every pair of communicating processes? What is the capacity of a link? Is the size of a message that the link can accommodate fixed or variable? Is a link unidirectional or bi-directional? Who gets the message?

How are processes created in an operating system?

Processes may create other processes through appropriate system calls, such as fork or spawn. The process which does the creating is termed the parent of the other process, which is termed its child. Each process is given an integer identifier, termed its process identifier, or PID.

How are embedded operating systems used in embedded systems?

Embedded operating systems are designed to be used in embedded computer systems. They are designed to operate on small machines like PDAs with less autonomy. They are able to operate with a limited number of resources. They are very compact and extremely efficient by design.

What are the functions of time sharing operating systems?

Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.
