What is Multi-core processor?
A '''multi-core''' [[CPU]] is a [[computer]] [[processor]] which has two or more sections. Each section of the chip executes instructions as if it was a separate computer. The actual processors are still on one chip. On this chip every core looks mostly like the other. They are several mostly independent cores which work together in parallel. A '''dual-core''' processor is a multi-core processor with two independent [[microprocessor]]s. A quad-core processor is a multi-core processor with four independent microprocessors. As you might be able to tell from the prefix, the name of the processor is based on the number of the microprocessors on the chip. == History == In the 20th century most computers used single-core processors and not multi-core processors. Multi-core solutions were only used in unusual cases. The usual way to make a computer faster was to increase the [[clock rate]]. But at a frequency about 4&nbsp;GHz the CPU would get too hot and take a lot of [[electricity]]. This was the point when multi-core processors became more important. Therefore, the demand for multi-core processors increased. In the second half of 2006 the best processors were dual-core processors. Since 2006 the development has gone on, so that the new processors get four, eight, or more independent microprocessors. Today, single-core processors are not used in new [[personal computer]]<nowiki/>s, but they remain popular in [[embedded system]]s which do not need a fast processor. ==Advantages== * A multi-core processor in a [[computer]] will work faster for certain [[computer program|programs]].<ref>{{Cite web|title=Should You Always Get a PC With the Highest Number of CPU Cores?|url=https://www.lifewire.com/multiple-core-processors-832453|access-date=2024-03-24|website=Lifewire|language=en}}</ref><ref>{{Cite web|title=Single-core vs. multi-core CPUs|url=https://www.networkworld.com/article/971425/single-core-vs-multi-core-cpus.html|access-date=2024-03-24|website=Network World|language=en}}</ref> * The computer may not get
