The printed circuit board that wires all other computer parts together is the motherboard, and it includes the CPU and memory. Each computer internal part 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. Processors are distinguished by clock speed measured in gigahertz (GHz) and bandwidth measured in bits, and they are divided into two groups namely single core and dual core processors. Multimedia production needs a very fast processor ideally structured to work on digital media contents, files, spreadsheets and presentation. The random access memory or RAM affects computer performance which serves as a temporary location in executing instructions from your computer such as running programs and applications. Greater amounts of RAM means running more programs at once with a faster speed, and the ideal RAM for gaming, producing DVD and video editing is 3 to 4 GB.
The hard drive or hard disk is where information such as uploaded pictures, music files, drivers and video recordings are stored, measured in megabytes.
