Quiz Bus Architecture

Which of the following best describes the function of the PCIe lanes in a computer system?

• They connect external devices to the power supply.

• They carry data between the CPU and expansion cards.

• They provide a path for power to travel between the CPU and the motherboard.

• They regulate the clock speed of the CPU.

What is the maximum data transfer rate per lane for PCIe 4.0?

• 8 GT/s

• 16 GT/s

• 32 GT/s

• 64 GT/s

Which type of bus architecture allows data to be transferred one bit at a time?

• Parallel bus

• Serial bus

• PCI bus

• AGP bus

What is the role of the address bus in a computer system?

• To carry data between the CPU and memory.

• To send control signals from the CPU to devices.

• To carry memory addresses from the CPU to RAM or devices.

• To provide power to the CPU.

Which of the following is a key difference between PCI and PCIe?

• a) PCIe uses lanes for data transfer, while PCI does not.

• b) PCI can transfer more data than PCIe.

• c) PCIe is slower than PCI for graphics cards.

• d) PCI uses serial communication, while PCIe uses parallel communication.

What is the primary benefit of using an M.2 SSD over a traditional SATA SSD?

• M.2 drives are larger and can store more data.

• M.2 drives have faster data transfer speeds due to the use of PCIe lanes.

• M.2 drives use less power than traditional SSDs.

• M.2 drives are more reliable than SATA SSDs.

In the context of PCIe, what does x16 represent?

• The amount of power the slot can provide.

• The number of lanes assigned to a device.

• The number of devices that can be connected to a slot.

• The clock speed of the device.

Which component of the chipset primarily manages communication between the CPU and high-speed devices like RAM and graphics cards?

• Southbridge

• Northbridge

• Platform Controller Hub (PCH)

• Expansion bus

What is a data bus responsible for in a computer system?

• Sending memory addresses from the CPU to RAM.

• Carrying control signals from the CPU to devices.

• Transferring data between the CPU, memory, and peripherals.

• Managing communication between the Northbridge and Southbridge.

Which of the following best describes the advantage of a 64-bit CPU architecture over a 32-bit CPU?

• It can handle more data at once and access more memory.

• It can run both 32-bit and 64-bit software more efficiently.

• It uses less power for the same performance.

• It allows for faster control signal processing.
