What is dual core processor?

A dual core processor is a CPU with two separate cores in the same chip. Each core has its own
cache. A dual core processor is an equivalent of two microprocessors in a computer. In a dual core
processor, both cores handle incoming data strings simultaneously, resulting in improved efficiency.
Hence a dual core system is faster than a single-core or traditional processor system. A dual core
processor does not require a new motherboard, but can be used in existing boards having the
correct socket. Intel and AMD are the companies that are making dual core processors.
Answer options D and B are incorrect. AMD Athlon(tm) and Intel Pentium 4 are not dual core
processors.
