Q: It's a dual core procossor
A: In this instance, it means you have 2 cores inside one processor packages, hence the name Dual-core. A dual-core is basically a chopped-down version of a multiprocessor system. To elaborate: The processor is the part of the computer that processes the program instructions. If your system has more than one processor (or in this case, more than one core), it is capable of processing instructions from multiple programs at the same time (or more specifically, from multiple threads at the same time). This differs from 'running' multiple programs at the same time on a single processor (or single core) where the instructions of each program (or thread) are executed in a round-robin style to give the 'feel' that all the programs are running at the same time.
