The motherboard is a printed circuit board that wires all other computer parts together, and it includes the CPU and memory. Every component of a computer directly connects into the motherboard, which offers expansion options for additional devices and high-end graphic displays. The computer’s processor is the single most important factor in determining a computer system’s performance. The quality and speed of the computer processor dictates the performance of the entire system, and other devices only allow the processor to reach its fullest potential. Computer processors are divided into two groups namely single core and dual core processors, and are distinguished by clock speed measured in gigahertz (GHz) and bandwidth measured in bits. Multimedia production requires a very fast processor structured to work on digital media contents, files, spreadsheets and presentation.
