TEZPUR 2025 — Computer PYQ

The correct answer is both (c) and (d) depending on the architectural context, though typically in multiple-choice questions of this nature, both are considered external to the motherboard assembly itself.

• CPU Socket: This is an integral part of the motherboard designed to hold the Central Processing Unit.

• RAM Slots: These are physical slots soldered onto the motherboard to house memory modules.

• Graphics Card: While motherboards have PCIe slots to connect a graphics card, the graphics card itself is a separate expansion card (or integrated into the CPU/chipset), not a component built directly into the motherboard.

• Power Supply Unit (PSU): This is a separate physical unit housed in the computer case that converts mains AC to low-voltage DC power for the internal components. The motherboard only contains the power connectors to receive this power.

To understand the relationship between these components, we can express the total system power requirement $P_{total}$ as:

$$P_{total}=P_{CPU}+P_{RAM}+P_{GPU}+P_{Motherboard}+P_{Others}$$
