Have a scratchpad, pencil, and calculator on you to work this question.
Assume that a PCI-Express bus consists of 32 lanes. Each lane is capable of a maximum data rate of 600 MB per second. Lanes are allocated to a device 1, 2, 4, 8, 16, or 32 lanes at a time. Assume that the PCI-Express bus is connected to a high definition video card that is supporting a 1920 × 1080 true color (3 bytes per pixel) progressive scan monitor with a refresh rate of 150 frames per second. How many lanes will this video card require to support the monitor at full capability?
