A core may refer to any of the following:

1. In relation to computer processors, a core is the processing unit that receives instructions and performs calculations, or actions, based on those instructions. A set of instructions can allow a software program perform a specific function.

Processors can have a single core or multiple cores. A processor with two cores is called a dual-core processor and four cores is called a quad-core processor. Processors for home computers can even have six or eight cores. The more cores a processor has, the more sets of instructions the processor can receive and process at the same time, which makes the computer faster.
