(5) .Multiprocessing Operating System

(Multiprocessing Operating System in Hindi)

A computer with this type of operating system has more than one processor and all these processors work simultaneously, so that the work given to the computer is completed soon. This type of computer has more than 1 processor,

Apart from the processor, the remaining components like memory etc are the same as the single processor.

(Computer concepts can be understood quickly if understood with examples.

(You can understand multiprocessing os in such a way that if you are building a house, if more than one mason is building a house then the house will be built quickly, just as more than one processor will work, then computer work will also be quick.)

types of multiprocessing operating system

Tightly coupled system: –

Such a system has only one RAM i.e. main memory and it is shared between all the processors. Sometimes there is a conflict in sharing of main memory in a tightly coupled system.

In this type of system, there is a very good synergy between all the tasks because the memory is the same.

(Example – if all the masons build houses with cement in the same vessel)

Loosely coupled system: –

In this all processors have their own local memory which they do not share among themselves. It has a master processor that maintains synergy between all processors.

Since all processors have their own memory in this type of system, there is no conflict of memory sharing. In this type of system, there is not that much synergy between all the tasks because the memory is different.

(Example – if all the masons have their own utensils filled with different cement.)


The examples given here are 100% correct and for your understanding, other such examples can also be taken.

(6) .Time Sharing Operating system

(Time Sharing Operating system in hindi)

There are many terminals attached to a main computer. There are different programs running at all terminals. The operating system gives all terminals a fixed time and the terminals programs execute in a circular queue at their own fixed time.

The CPU speed of the main computer is so fast (in microseconds 10-6 or nano seconds 10-9), that the users sitting at all the terminals feel that they are running their own separate computer while they are only running the terminals. not a computer.

Terminal: – They are used only for input / output, not for processing.

(7) .Real Time Operating System

(Real Time Operating System in hindi)

It works just like the time sharing OS, the only difference is that in the time sharing OS, if the program is not executed in the given time for execution of a terminal’s program, then that program is removed from the CPU, The operating system does not give that program extra time for processing and gives cpu another program for processing.

But in Real Time OS, the operating system will not remove that program but will give it extra time for processing.

The response time of C.P.U is very important in Real Time Operating System. This type of OS works in real-time.

In Real Time OS, the time required to process input and give responce to the user is very less. This time interval is called the response time.

A real-time operating system is used when the importance of time is very high. For example missile launching system where the missile has to be launched at a certain time,

railway reservation system, air traffic control etc.
