Final answer:
The concept that uses multiple or multi-core processors to share processing tasks is known as parallel computing. While operating systems and compilers support parallel computing, they do not share tasks across processors. Database management systems can use parallel computing for performance improvement.
Step-by-step explanation:
The concept mentioned in the question, which uses multiple processors, or multi-core processors, to share processing tasks is known as parallel computing. Parallel computing is a type of computation in which many calculations or processes are carried out simultaneously. Large problems can often be divided into smaller ones, which can then be solved concurrently across multiple processors or cores. This technique is widely used in various high-performance computing applications.
Operating systems manage the hardware resources and provide services for computer programs. An operating system can facilitate parallel computing but is not in itself the process of sharing tasks across processors.
A compiler is a program that translates source code written in a programming language into machine code that a computer's processor can execute. While some compilers can optimize code for parallel execution, compilers themselves do not perform the parallel processing.
Database management systems (DBMS) can use parallel computing to improve performance on large databases by executing multiple queries or transactions concurrently.
