The main difference between batch processing and multiprogramming is that batch processing allows multiple programs to execute with minimum human interactions while multiprogramming allows multiple programs to execute on a single processor system.
A computer system has an operating system to manage the functionalities of the entire system. Moreover, different systems follow various methods to perform tasks. Batch processing and multiprogramming are two of these methods.

What is Batch Processing
Batch processing is the method that allows programs to execute without much human interaction. The jobs in batch processing can execute without end-user interactions. Moreover, these systems can start on their own according to the available resources. In addition, a special program called the monitor manages the execution of the other programs in the batch. And, this monitor is present in the main memory. In batch processing systems, the input data is preselected using scripts or command line parameters.
Batch processing provides a number of advantages. It allows multiple users and programs to share computing resources. Moreover, it is also possible to shift the jobs to resources that are not busy. Additionally, it waits a long time to get computer resources. Furthermore, it reduces costs and requires minimum manual supervisions.
What is Multiprogramming
Multiprogramming is the method of allowing several programs to run at the same time on a uniprocessor. There are multiple programs. The operating system executes part of each program at a time. However, it appears to the user that all programs execute simultaneously. Unlike in non-multiprogramming systems, in multiprogramming systems, the CPU always executes a program.
Moreover, if there is a memory protection method in the system, then there is less chance for a bug in one program to interfere with another program. In addition, when there are more memory protection mechanisms, there can be changes in the content of storage. Thus, it can cause the system to crash. Furthermore, it can be difficult to debug as it is difficult to find which program had the fault.
Difference Between Batch Processing and Multiprogramming
Definition
Batch processing is the grouping of several processing jobs to be executed one after another by a computer without any user interaction while multiprogramming is the ability of an OS to execute multiple programs at the same time on a single processor machine. Thus, this is the main difference between batch processing and multiprogramming.
Speed
Speed is also an important difference between batch processing and multiprogramming. Batch processing is slower while multiprogramming is faster.
CPU
In batch processing, the CPU might stay without performing a task (does not wait idle); however, in multiprogramming, the CPU always perform a task.
Usage
Another difference between batch processing and multiprogramming is their usage. Batch processing helps to minimize human interactions and cost while multiprogramming provides maximum CPU utilization.
Conclusion
Both batch processing and multiprogramming are two methods of a computer system to perform tasks. In brief, the main difference between batch processing and multiprogramming is that batch processing allows multiple programs to execute with minimum human interactions while multiprogramming allows multiple programs to execute on a single processor system. Furthermore, both of these methods allow resource sharing.
