What is the difference between multitasking multiprogramming and multithreading?
Multiprogramming is a rudimentary form of parallel processing in which several programs are run at the same time on a uniprocessor.Since there is only one processor, there can be no true simultaneous execution of different programs. Instead, the operating system executes part of one program, then part of another, and so on. To the user it appears that all programs are executing at the same time. Multitasking, in an operating system, is allowing a user to perform more than one computer task (such as the operation of an application program) at a time. The operating system is able to keep track of where you are in these tasks and go from one to the other without losing information Multithreading is the ability of a program or an operating system process to manage its use by more than one user at a time and to even manage multiple requests by the same user without having to have multiple copies of the program running in the computer
What is a single user multi tasking operating system?
The two concepts build upon each other. A single tasking (ST) operating system is necessarily a single user (SU) operating system, but a single user operating system may be a multi-tasking (MT) operating system. For example, MS-DOS is a SU, ST operating system (there was only one "user" and only one program could run at a time), Microsoft Windows 3.1 was a SU, MT operating system (only one user could be logged in at a time, but multiple tasks could run at once), and Windows XP is a multiple user (MU), MT system, as multiple users could be logged in at once, and multiple tasks could be run at once. There is no known example of a MU, ST operating system.
What mean by multithreaded program?
A multithreaded program is one that has multiple threads in execution. They may execute parallel to one another or totally without relation to one another. In Java you can create multithreaded programs using Java threads.
What is one disadvantage of single user operating system?
Only one user is allowed to work on this type of operating systems.
What is dovetailing in cookery?
Doing more than one thing at once. For instance: washing some dishes while your food is in the oven.
What Is the word for the execution of multiple tasks at one time?
Multitasking is the word used for the execution of multiple tasks at one time.
What Is the name execution of multiple tasks at one time?
In computing this would be called "parallel processing" or "multithreading."
What is serial execution?
Serial execution is when tasks are completed consecutively (one after the other), as opposed to concurrently (at the same time, in parallel).
Descibe multi task oriented?
It means to have ability to do multiple tasks at one time, meaning running various tasks or operations in parallel with each other at same time.
What is serial sequential?
Serial sequential refers to a specific type of processing or execution order where tasks or operations are completed one after the other in a linear fashion, with each task depending on the completion of the previous one. This approach contrasts with parallel processing, where multiple tasks are processed simultaneously.
Can the execution time of a task be reduced by using many processors?
Yes, the execution of a task can be reduced by using multiple processors. Using more than one processor helps speed up a task.
Does the use of multiple cores on one CPU chip allows the execution of two or more sets of instructions at the exact same time?
yes
Does the use of multiple cores on one CPU chip allow the execution of two or more sets of instructions at the exact same time?
yes
What are the two types of instruction execution?
The two types of instruction execution are pipelining and not pipelining. Pipelining involves breaking down instruction execution into multiple stages that can overlap, improving efficiency. Not pipelining involves executing one instruction at a time without overlapping stages.
'What is the difference between multiprogramming and multitasking and what is meaning of a task if we consider a task as a program then the concept will be multiprogramming then what is the differenc?
First of all there is difference between program and a task. There may be multiple tasks running related to one program at the same time. so if the processor is busy in multiple tasks related to one program then it is multitasking. But if the multiple tasks which the processor is executing concurrently are related to different independent programs then the concept is know as multiprogramming.
What is the purpose of Java sleep?
It pauses the execution of the program (or of the thread where it is invoked, if you have multiple threads), for the specified time.It pauses the execution of the program (or of the thread where it is invoked, if you have multiple threads), for the specified time.It pauses the execution of the program (or of the thread where it is invoked, if you have multiple threads), for the specified time.It pauses the execution of the program (or of the thread where it is invoked, if you have multiple threads), for the specified time.
What the activity in which computer works on more than one processat a time?
The activity in which a computer works on more than one process at a time is known as multitasking. This capability allows the operating system to manage multiple tasks simultaneously, switching between them quickly to give the illusion of parallel execution. Multitasking can involve running multiple applications or processes concurrently, enhancing overall efficiency and user experience. It is fundamental to modern computing, enabling users to perform various operations without noticeable delays.
