Can execute multiple programs simultaneously in a single CPU so this single execution core is shared among programs?
Yes, a single CPU can execute multiple programs simultaneously through a process called multitasking. This is achieved using techniques like time slicing, where the CPU rapidly switches between tasks, giving the illusion of simultaneous execution. Additionally, modern operating systems manage resource allocation and scheduling to optimize performance, allowing multiple programs to share the CPU's execution core effectively. However, true parallel execution requires multiple CPU cores.

Why cant a single computer processor execute two or more programs simultaneously?
In simple terms a single processor can only process one machine instruction at a time; it's just not possible to execute two or more instructions simultaneously and therefore not possible to execute 2 programs simultaneously. However, it's not quite as simple as that because a modern processor can have 2 or more cores, in which case it is possible to execute 2 or more instructions simultaneously. However, that's not quite the same thing as executing 2 programs simultaneously as we invariably execute far more threads of execution than we have cores available. Note that a program consists of one or more processes and a process consists of one or more threads of execution. Although it is theoretically possible to execute two threads simultaneously upon two cores, when those cores share the same processor they also share the same L2 cache and that's really only beneficial when both threads share the same process. With 2 independent processors there's a better chance of simultaneous program execution, however it's nigh on impossible to guarantee this unless the system is specifically designed for that purpose. In a multi-processing, multi-threaded environment, task-switching makes it next to impossible for any two independent programs to execute simultaneously because every thread has to yield to waiting threads.
What is real-time software?
Programs that are designed to run immediately without a scheduled time or after execution is known as real time software. This enables to user to execute a number of activities and tasks simultaneously.
What is the name for multiple processors running simultaneously to execute a single task?
Parallel processing
Method of processing that uses multiple processors simultaneously to execute a program?
Parallel Processing
What is the main advantage of multiple programming?
The main advantage is that multiple programs can run concurrently on the same processor. Given that there is only one processor, the programs cannot execute simultaneously as they would on a multi-processing system with independent CPU cores. Instead, each program must periodically yield control back to the system in order to allow other threads of execution to make use of the CPU. Modern operating systems can do this automatically, periodically saving the current thread's "state" and switching to the next thread of execution in the queue.
How do you define a process in rtos?
RTOS(Real Time Operating System) can execute multiple programs concurrently. At any time there may be tens of programs executing on a RTOS. A program in execution is called a process. SOMA VARMA G
Control unit of a digital computer is to?
Read & Execute instructions provided during execution of Programs.
What is used in vb 6.0 for execution of programs?
I think events of objects are used to execute a program in VB.
What is diffence beween multiprogramin and multiprocessing?
Multiprogramming is a technique that allows multiple programs to reside in memory and be executed by a single CPU, enabling efficient use of CPU time by switching between programs when one is waiting for I/O operations. In contrast, multiprocessing involves using multiple CPUs or cores to execute multiple processes simultaneously, enhancing performance and throughput. While multiprogramming improves resource utilization by overlapping I/O and CPU operations, multiprocessing increases computational power by leveraging parallel execution.
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.
How many threads can core 2 duo processor execute simutaneously?
Since the core 2 duo processor has two execution units, it can execute two threads simultaneously. (If you said quad instead of duo, the answer would be four.)
How can I efficiently execute a Python run loop in parallel?
To efficiently execute a Python run loop in parallel, you can use libraries like multiprocessing or threading to create multiple processes or threads that run simultaneously. This allows you to take advantage of multiple CPU cores and speed up the execution of your loop. Be sure to carefully manage shared resources and handle synchronization to avoid conflicts between the parallel processes or threads.
