If the PCB were kept in secondary memory, it would be too slow for the operating system to access. In some cases, the PCB may be swapped out to secondary memory if main memory is low. However, the PCB is typically kept in main memory as much as possible. Am I correct sir ?
When a process is created (for example, by executing a new program), it enters the "new" state. At this point, the operating system may allocate some resources for the process, but it doesn't create a full PCB yet.
Every process has pcb... In new state it's pcb present in the job queue..... If it's get ready then it is moved to next queue.... But every queue is present in os only
When a process is created, the operating system allocates memory for its PCB in the main memory. This allocation allows the operating system to efficiently access and manage the process's control block during its execution. Storing PCBs in main memory ensures fast and direct access to process information, which is essential for the efficient management of processes by the operating system. By-Abhinav
@@ishratkaur1605 both the queues and the PCBs are kept are kept in the main memory, but in different sections of the memory. The ready queue,s wait queues consists of only processes.
@@ishratkaur1605 For example, a shopkeeper maintains a ledger of his inventory, while all the stuff and the ledger are kept inside the shop, the ledger is under the shopkeeper's authority and in the ledger he writes which items are placed on which shelf. Here the shop is the main memory, the shopkeeper is OS and the shelves are the queues and the items kept on the shelves are the processes. Hope this analogy helps you understand.
hi, job scheduler contains processes or pcb's/, because text book and other reference books are specifying the same of having job queue in secondary memory and job queue will have the processes itself. The processes are brought into main memory by swap in and then the corresponding PCB are appended to the ready queue for execution. can anybody clarify this doubt please?

New: The process that is just being created. The Program Control Block is already being made but the program is not yet loaded in the main memory. The program remains in the new state until the long term scheduler moves the process to the ready state (main memory).
bro 10:20 sir told that all the process which are in new state remains in job queue .And job queue remains in main memory's Os part. So Can we say PCB will created when the process in new state and kept in main memory Os part(in Job queue) ?
@@i_am_wiz that means you are saying pcb of new state processes are maintained in secondary storage?? But i used to know that pcb of processes are maintained in kernel space of os which is in main memory.
sir I have a doubt all the processes are there in queue data strucure so schedulars can onlu run the process came first it cannot decide of it's own rght?? or it can??

I am not interested in any subject no more... Which is not being taught by Visva Sir...😄 ✨✨🧨
When a process is created (for example, by executing a new program), it enters the "new" state. At this point, the operating system may allocate some resources for the process, but it doesn't create a full PCB yet.
Sir,I have one question:
1. Where is the present when the process is in suspended state??
Swap Space
Every process has pcb...
In new state it's pcb present in the job queue..... If it's get ready then it is moved to next queue....
But every queue is present in os only
Its really happy learning
I am really thankful for YOU...sir

When process is in running state or suspended state , where the pcb is kept , like in which queue
PCBs aren't kept in any queue, they reside in the main memory section which is reserved by OS
@@shivamkumar-eq3sl But these queues also reside in main meory ...

Thank you Sir ☺️
how long term schedular max the degree of multiprogramming?can anyone pls explain .
sir why it is dangerous if process goes from running to suspended ready state?
Lecture 1,2 ke notes hi h t kya telegram pr
aur lecture ke notes nhi mil rhe
what is the difference between process in a new state and a program
Thank You
you are amazing sir
sir new state present in secondary memory or main memory?
When a process is created (initialized or installed), the operating system creates a corresponding process control block.
Do proccesses in 'New' State have PCB's ?
24:10 Memes😁 bor nhi hone dete sir💙
Are short term scheduler and dispatcher same.
Sir said, short term schedular selects process but dispatcher moves it from ready to running state.
@@priyasharmax I got it, tutorials point have an article and they have written that they are same , so I got confused. Tq
Newly created PROCESS mustnhave P.C.B , which is stored in the O.S itself.
A pcb created in kernel whenever new process is started and stored in MM in OS's private section......
@@lsdxsaurabh2798 But Kernel Space and OS's private section in Main Memory is the same.
@@ishratkaur1605 yeah
If PCB in a new state then it is in hardisk
yes
In javatpoint, i read that long term as well as reduce the degree of multi-programming, so what is the ans of ques at 53:00??
U luk like my gf
if the question was who controls degree of multiprogramming then it would be both, in this case answer should be mid-term programming only

But job queue resides in secondary memory , ???!? Am I wrong ??
No every que resides in main memory's OS part .
sir dispatcher ke bare me aapne bataya nahi tha bas itna he bataya tha ke context switch ko hone ke leya softer use bas itna he bataya tha
25:48
in which queue PCB of suspended state store?
PCB Is prop of OS SO in OS part of the main memory ...so no queue for PCB"s
