Detailed explanation-1: -It allows more efficient use of the computer hardware; when a program is waiting for some external event such as a user input or an input/output transfer with a peripheral to complete, the central processor can still be used with another program.
Detailed explanation-2: -Multiprogramming’s main purpose is to manage all of the system’s resources. The file system, transient area, command processor, and I/O control system are the main components of a multiprogramming system. As a result, the multiprogramming OS is built to store many programs based on sub-segmenting the transient area.
Detailed explanation-3: -Multitasking: Allows more than one program to run concurrently. Multithreading: Allows different parts of a single program to run concurrently.
Detailed explanation-4: -Multiple modes could be used to provide a finer-grained security policy. For example, rather than distinguishing between just user and kernel mode, you could distinguish between different types of user mode. Perhaps users belonging to the same group could execute each other’s code.
Detailed explanation-5: -Multi-processing is a process that allows the system to simultaneous processing of two or more programs with the help of multiple processors.
