1.4. MotherboardYour PC's motherboard , a large flat, rectangular piece of circuitry , serves as a platter for your computer's brains , memory, cards, and connectors. Everything inside your PC ultimately connects to the motherboard, which shuttles information between the parts . Since the motherboard lies buried deep inside your PC, you'll spot it only under a few circumstances: when replacing the battery, replacing the power supply (Section 1.9), adding memory (Section 1.6), or adding cards (Section 1.7). When rummaging inside your computer during one of those tasks , use Figure 1-4 as a roadmap. |
