Parallel means that two or more tasks are executed at the same time. This is possible only if the CPU supports it, requiring multiple cores to achieve parallelism. However, modern CPUs are typically multi-core, and single-core CPUs are largely outdated and no longer widely used, as they are significantly outperformed by multi-core ones. This shift is because modern applications are designed to…
