What is inter-process communication in Linux?
What is inter-process communication in Linux?
Inter-process communication (IPC) is a mechanism that allows processes to communicate with each other and synchronize their actions. The communication between these processes can be seen as a method of co-operation between them. Processes can communicate with each other through both: Shared Memory. Message passing.
How do you communicate between processes in Linux?
Inter-process communication in Linux: Shared storage
- Shared files.
- Shared memory (with semaphores)
- Pipes (named and unnamed)
- Message queues.
- Sockets.
- Signals.
How pipes are used in inter-process communication in Linux operating system?
Pipe is widely used for communication between two related processes. Message passing is a mechanism for a process to communicate and synchronize. A message queue is a linked list of messages stored within the kernel. Direct process is a type of inter-process communication process, should name each other explicitly.
How is IPC handled in Linux?
The Linux kernel provides the following IPC mechanisms: Signals, Anonymous Pipes, Named Pipes or FIFOs, SysV Message Queues, POSIX Message Queues, SysV Shared memory, POSIX Shared memory, SysV semaphores, POSIX semaphores, FUTEX locks, File-backed and anonymous shared memory using mmap, UNIX Domain Sockets, Netlink …
What is inter process communication?
In computer science, inter-process communication or interprocess communication (IPC) refers specifically to the mechanisms an operating system provides to allow the processes to manage shared data. Many applications are both clients and servers, as commonly seen in distributed computing.
What are the types of inter process communication?
Methods in Interprocess Communication
- Pipes (Same Process) – This allows flow of data in one direction only.
- Names Pipes (Different Processes) – This is a pipe with a specific name it can be used in processes that don’t have a shared common process origin.
- Message Queuing –
- Semaphores –
- Shared memory –
- Sockets –
How signals can be used for inter-process communication?
Signals are standardized messages sent to a running program to trigger specific behavior, such as quitting or error handling. They are a limited form of inter-process communication (IPC), typically used in Unix, Unix-like, and other POSIX-compliant operating systems.
What is the need for inter process communication?
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.
How many types of IPC are there?

What are sockets in Linux?
Sockets are the constructs that allow processes on different machines to communicate through an underlying network, being also possibly used as a way of communicating with other processes in the same host (through Unix sockets).
What is a thread in OS?
A thread is a single sequential flow of execution of tasks of a process so it is also known as thread of execution or thread of control. There is a way of thread execution inside the process of any operating system. Apart from this, there can be more than one thread inside a process.
What is inter-thread communication in Java?
Inter-thread communication in Java. Inter-thread communication or Co-operation is all about allowing synchronized threads to communicate with each other. Cooperation (Inter-thread communication) is a mechanism in which a thread is paused running in its critical section and another thread is allowed to enter…
How do you communicate between threads in Linux?
You could also use most traditional inter-process communication mechanisms between threads, e.g. a pipe (7) (probably with poll (2) …). So read Advanced Linux Programming and study syscalls (2) and pthreads (7) Avoid using signal (7) -s between threads and be aware of signal-safety (7).
What are pipes in Linux interprocess communication?
Get the highlights in your inbox every week. This is the second article in a series about interprocess communication (IPC) in Linux. The first article focused on IPC through shared storage: shared files and shared memory segments. This article turns to pipes, which are channels that connect processes for communication.
What is the use of notify() method in threading?
If you call notify () or notifyAll () method, thread moves to the notified state (runnable state). Now thread is available to acquire lock. After completion of the task, thread releases the lock and exits the monitor state of the object.
