PCs work by integrating several key components: the CPU (Central Processing Unit) processes instructions; RAM (Random Access Memory) stores temporary data for quick access; the hard drive or SSD (Solid State Drive) provides long-term storage; and the motherboard connects all parts. Graphics cards handle visual processing, and power supplies provide necessary energy. Operating systems manage software and hardware interaction, while input devices like keyboards and mice, and output devices like monitors, facilitate user interaction.
