Cyber Fundamentals Block 2 Practice Exam

Form factor is about the physical size and layout of the motherboard—the actual length and width, where mounting holes sit, and where the I/O shield is located. This matters because cases, power supplies, and many expansion components are built to fit specific dimensions and mounting patterns, so a motherboard must match the case and space available. CPU socket type is about which processors the board can physically support, not its size. RAM density describes memory modules and capacity, not the board’s dimensions. Expansion slot count indicates how many add-in cards you can install, which affects expandability but not the motherboard’s physical size. Common form factors like ATX, Micro-ATX, and Mini-ITX illustrate how different dimensions and mounting layouts determine compatibility with cases and other components. So the correct idea is that form factor refers to the physical dimensions.
