How Data Travels Around the Processor

Silcon is one of the materials used for creating processors.

Considered the brains of a computer, the central processing unit or processor calculates data and interacts with other computer components. Data travels to and from the processor to create what users see on the screen. A computer bus transfers data into and out of the processor.

History

Before quad-core processors, manufacturers like IBM simply labeled their processor by a three- to five-digit number. In 1986, IBM created the first personal computer, which incorporated the 8088 processor. The higher the last three digits attached to a processor represented a higher speed. Intel created the 586 processor also known as the Pentium chip.

Function

The processor decodes data instructions sent by way of computer buses, which act as a roadway for incoming and outgoing instructions and operations. A processor receives instructions such as opening a web browser, calculates the process, performs the operation then saves the results of the action in nanoseconds.

Speed

Computer buses and processors vary in size. A larger bus allows more data to flood from one end to the other, allowing a capable processor to compute more data. A processor with a higher clockspeed calculates data faster than a processor with a lower clockspeed.
