What is a chipset?

• A. The main memory modules.
• B. The controller logic that handles I/O, storage, PCIe lanes, and legacy interfaces between CPU and peripherals.
• C. The mechanical interface for CPU seating.
• D. The power supply unit.

Answer: (B)

A chipset is the controller logic on a motherboard that coordinates how the CPU talks to the rest of the system. It handles I/O, storage, PCIe lanes, and legacy interfaces, acting as the bridge between the CPU and peripherals. In modern systems, the chipset manages data flow between the CPU, memory subsystem, and devices like GPUs, SSDs, NICs, USB controllers, and other expansion interfaces, including the available PCIe lanes. It also provides support for older interfaces when needed. The other options miss the core role: main memory modules sit in memory slots, not in the chipset; the mechanical interface for seating the CPU is the socket; and the power supply unit provides power, not logic control.
