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 has direct connection into the motherboard, that also provides expansion options for additional devices and high-end graphic displays. The processor or CPU is basically the brain of a computer, that is why it is very important part that greatly affects 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.

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. The ideal RAM for gaming, producing DVD and video editing is 3 to 4 GB, and higher the RAM, the more you can run different programs at once with a faster speed.
The hard disk or hard drive stores the information saved on your computer such as pictures you upload, files and video recordings, measured in megabytes.
