FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Parallel running is a strategy for system changeover where a new system slowly assumes the roles of the older system while both systems operate simultaneously. This conversion takes place as the technology of the old system is outdated so a new system is needed to be installed to replace the old one.

Detailed explanation-2: -The parallel processing system is designed to speed up the execution process of programs by dividing them into multiple segments and processing them simultaneously. These systems are called multiprocessor systems or tightly coupled systems.

Detailed explanation-3: -Summary. Parallel operating systems are the interface between parallel computers (or computer systems) and the applications (parallel or not) that are executed on them. They translate the hardware’s capabilities into concepts usable by programming languages.

Detailed explanation-4: -As the name suggests, parallel implementation involves running both systems concurrently until the business is ready to make the switch from old to new.

Detailed explanation-5: -Another changeover technique is a parallel changeover. In this case, both old and new systems run side-by-side for a while. This allows a direct comparison between the systems, letting users ensure the new system is working correctly before the old system is terminated.
