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.

Great man!!

12 min youtube video better than a 2 hour lecture by my prof lmao

[@manichandu2742]

Seriously broo 😂

With 2x speed 😂

[@derekdj6790]

I love the pause before the end of each sentence constantly keeping us in an endless cycle of suspense!

[@ayushbhardwaj582]

I scrolled to see if someone else noticed too XD

[@rishabhratan2925]

and m just watching it at 1.75x

[@kaivalyadeshpande3527]

There is no any pause for 2X 🙂

[@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.

[@alasgar_alakbarov]

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

[@hackaniceday]

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

[@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.

[@dunzek943]

Thank you. Simple yet comprehensive.

[@saadmanahmed860]

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

[@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

[@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?

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?

you r rt tbh your explanation is the best

[@ganeshkutum4740]

Sir please upload the remaining topics as soon as posible

[@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.

[@thrang_eo]

Awesome well explained 🙏

[@nareshreddybolla975]

no one can tell like this ,good

I hope topics like CPU SCHEDULING are covered ahead in remaining last 3-4 lectures (which are essential for GATE)

[@saadmanahmed860]

best illustration

[@sidduvenkateswararao7996]

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.

[@vasukurumeti3110]

can you please give any live example for message passing?

[@kiche_allan]

Love the video

[@arunalakshmi1514]

Is the interprocess communication and models of process communication both same or not

[@NasirAli-ly5io]

I got everything, but; how kernel will know , to whom the message is to be passed...???

[@66565]

Tq

[@natiiim6336]

messages is with pipes and messages queues?

[@easycoding9095]

Please upload videos on Deadlock

[@khaledahmed2867]

any tutorial how to implement message passing via java ?

[@priyankasatarkar2559]

good

[@ashutoshmishra1603]

Very Good teaching style. But Please explain with practical code

[@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.

[@sachinpal2424]

I had expected a little more in-depth explanation.

[@minhhoangcong9155]

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

[@_cutie526]

Please unlock all videos we need your videos and support 🙏🙏🙏🙏

[@sonianegi8089]

So nice sir thnxx alot it help me
For my exam 😊😊😊

[@zey3169]

İt's said that for processes, they can share data* but in my thread lecture note it's said that only threads can share data not processes

[@chetanchauhan6970]

Interprocess communication and principle of concurrency is same??
