The document summarizes the internal and external parts of a computer. Internally, it discusses the motherboard, processor, fan, RAM, hard disk, power supply, and optical unit. Externally, it mentions the monitor, keyboard, mouse, speakers, modem, printer, and web cam. The motherboard connects all internal components, the processor interprets instructions and processes data, and the fan expels hot air to prevent overheating. RAM is used as working memory and the hard disk stores digital files.
