Question

Operating system

How do I run a program about processces and IPC on linux can someone show me an example and the step by step way of doing it. I have files tha were given and I need to run them.

Thank you

A method is of 2 type:

Independent method.
Co-operating method.
An freelance method isn't tormented by the execution of different methodes whereas a co-operating process is tormented by different capital punishment processes. although one will assume that those processes, that square measure running severally, can execute terribly with efficiency however in sensible, there square measure several things once co-operative nature is utilized for increasing process speed, convenience and modularity. bury method communication (IPC) may be a mechanism that permits processes to speak one another and synchronize their actions. The communication between these processes is seen as a technique of co-operation between them. Processes will communicate with one another mistreatment these 2 ways:

Shared Memory
Message passing
The Figure one below shows a basic structure of communication between processes via shared memory technique and via message passing.

An software package will implement each technique of communication. First, we are going to discuss the shared memory technique of communication so message passing. Communication between processes mistreatment shared memory needs processes to share some variable and it fully depends on however technologist can implement it. a technique of communication mistreatment shared memory is notional like this: Suppose method1 and process2 square measure capital punishment at the same time and that they share some resources or use some data from different process, process1 generate data regarding bound computations or resources getting used and keeps it as a record in shared memory. once process2 got to use the shared data, it'll register the record hold on in shared memory and note of the knowledge generated by process1 and act consequently. Processes will use shared memory for extracting data as a record from different method still as for delivering any specific data to different method.
Let’s discuss associate degree example of communication between processes mistreatment shared memory technique.

i) Shared Memory technique

Ex: Producer-Consumer downside
There square measure 2 processes: Producer and client. Producer produces some item and client consumes that item. the 2 processes shares a standard area or memory location referred to as buffer wherever the item created by Producer is hold on and from wherever the buyer consumes the item if required. There square measure 2 version of this downside: 1st one is thought as boundless buffer problem during which Producer will persevere manufacturing things and there's no limit on size of buffer, the other is thought as finite buffer downside during which manufacturer will produce up to a particular quantity of item and subsequently it starts watching for client to consume it. we are going to discuss the finite buffer downside. First, the Producer and also the client can share some common memory, then producer can begin manufacturing things. If the whole created item is adequate the dimensions of buffer, producer can wait to induce it consumed by the buyer. Sim-
ilarly, the buyer 1st check for the provision of the item and if no item is accessible, client can sit up for producer to provide it. If there square measure things out there, client can consume it.
