👉 Parallelisation is a technique used in computer science and software engineering to speed up the execution of programs by dividing them into smaller, more manageable parts called "parallel processes" or "threads." This allows for the use of multiple cores (or processors) on a single machine, thereby making it possible to execute the same program on different machines simultaneously. The term "parallelisation" is often used in conjunction with the phrase "distributed computing," which refers to the idea that computers can be distributed across many locations
