[@DaiMoscv]

Here is what I understood:
Interprocess Communication which provides an environment, allows process communication. And the reason why we need IPC:
Information sharing - when several users wants an access to an information it's essential to provide an environment which they can access at the same time.
Computation speedup - instead of taking one task at a time, it's better to divide the task to several subtasks which they all work for single task concurrently. In order to achieve this, the subtasks need to communicate each other.
Modularity - when designing a system, one person will not be designing whole system alone. Therefore, we divide the system to different modules and they'll be put together later on. Also these modules need to cooperate with each other.
Convenience - from user perspective, if they are utilizing multiple task at a same time meaning different processes are running concurrently. So it'd be convenient if those processes can communicate each other and avoid clashing to one another.
There are two fundamental models of Interprocess Communication:
1. Shared memory - There'll be shared memory region for cooperating processes which will be used for communicating by processes read and write to this memory region. For example: If A process writes an information in a memory region, B process will read the information and thus it can understand.
2. Message passing - Processes can communicate through Kernel by sending and receiving messages from Kernel.

[@zoverlvx8094]

The presentation on the topic was elegantly put. Simply beautiful. You've got another enchanted subscriber.

[@jaylee842]

Thank you so much, sir. Now I clearly get the concept of IPC.

[@ii-vo5zi]

You are simply awesome.i like your way of teaching that you clarifies a to z in a sentence.god bless you brother.

[@Anedonia-]

Finally I can understand the fundamentals about IPC. Straightforward explanation and without academic jargons.

[@alasgar_alakbarov]

Perfect explanation of the topic. Thank you very much, it was very useful.

[@abhishekmahor6700]

Thanks for supportive lecture now i am going to crack gate 2024.

[@hackaniceday]

This is the best IPC introduction before write code!! Thank you.

[@saadmanahmed860]

cooperating process needs communication.
* information sharing
*computation speedup
*modularity
*convenience
IPC has two mechanisms.
*shared memory
*message passing

[@eobardthaw]

Dear sir, you are the superior teacher & i solved my problem to understand this topic...thanks so much..

[@tarunkolli7871]

Such a great explanation which helped me lot for exams, converted a complex topic to simple topic...Thank you so much sir..

[@hoangminhchau2187]

If there are multiple processes running concurrently, they can be independent processes or cooperation processes.
- Independent process: can not be affected by or affect other processes
- Cooperation process: can be affected by or affect other processes
Reasons why processes are in cooperation:
- information sharing: different users want to share infos between them
- computational speed up: one task may be split into multiple processes in order to increase performance
- modularity
- convenience: user can use multiple programs at the same time, so IPC allow theses programs to run smoothly
Processes communicating with each other through IPC (inter processes communication)
There are 2 models of IPC:
- Shared memory: cooperating processes will read and write to a specific region on the memory
- Message passing: one process will send a message to the kernel and the kernel will send that message to the other process

[@philosphize]

Nice explanation sir

Thank u so much sir. Ur lectures are very helpful for me. And I am learning 🎉

[@HimanshuSharma-vt8ke]

Thanks so much neso academy and to the teacher for these lectures. I just have one doubt. I am unable to recall or think about any examples of two processes sharing data with each other. Can you give me an practical example of two processes working on the same data. I mean if I have opened an text file on ms word and also on notepad. And I start editing the document on both the programs, then is it an example of two processes sharing the same data?

[@abhijitmishra646]

Thank you for clearing my concepts:))

Semma bro.. Ur voice is super to hear and Al'so listen..

[@Abenakhen]

Thanks for this video. I felt it could be improved by less repetition of the same words that are written on the screen. I feel like you could give more examples of who this might be implemented earlier on. Also jump to the diagram and just change the labels as you go along. Also the IPC isn't always kernel. It is for sockets but often is implemented message bus / queue / pipe application.

[@rajeshbhowmik]

Thank you sir for such a beautiful explanation.

Hey, are the reasons for providing an environment that allows process co-operation, same as the advantages of inter-process communication?
If not, then what are the advantages of inter-process communication?

at @4.15, We can't get the speed if we run the several processes concurrently, I guess what you meant here is "parallelly" and this is possible only on the multicore processor.

Why proccess A can't directly send message to process B ?

in the advantages for cooperation processes--
2.Computational speed :
We are creating sub processes for speedup,but rather than creating process ,Thread is much better option and faster than sub-process.Can anyone please clarify this point?

you r rt tbh your explanation is the best

[@MrBendybruce]

I hear CPU reviewers often referring to "improved IPC performance" and decided I wanted to know what IPC actually was. Thanks for the video -can I assume then, that more modern CPU's (say Ryzen 3 series) have faster and more efficient chip esigns, that allow processes running on different cores to talk to each other?

[@nawnwa]

The IPC acronym that you are referring to is "Instructions per cycle". It is a measure of the performance of a CPU on how many instructions it can execute on average per cycle. There is good and simple article on wikipedia about it.

[@chetanchauhan6970]

Interprocess communication and principle of concurrency is same??
