Illustrated example of a dual-core processor.

With computer processors, dual-core is a technology that enables two complete processing units (cores) to run in parallel on a single chip. This gives the user virtually twice as much power in a single chip. For the computer to take full advantage of dual-core, it must be running on an operating system that supports TLP (thread-level parallelism) and for applications to support TLP.


You can think of a computer with dual-core as a computer with two CPUs (central processing unit). If the computer is a quad-core, you could think of that computer as having four processors.
