multitasking;

Like the word suggests, multitasking is doing multiple tasks at once. In terms of processing, multitasking allows the computer to stream through more data streams and programs. A dual core processor boosts the system's multitasking computing power. Dual core processors provide two complete execution cores instead of one. Sicne each core has its own cache, the operating system has sufficient resources to handle intensive tasks in parallel, which provides a noticeable improvement to multitasking.
