What is the throughput of the PC Card with a 16 bit bus?

1. 2.5 Gbps

2. 160 Mbps

3. 75W

4. 940 pin

The correct answer is: 160 Mbps

The throughput of a PC Card with a 16-bit bus is 160 Mbps, which is calculated based on the bus width and the data transfer speed. A 16-bit bus can transfer 16 bits of data simultaneously, and if the bus operates at the standard speed of 10 MHz, then the maximum data transfer rate can be calculated as follows: Throughput = (Bus Width in bits) × (Bus Speed in MHz) Throughput = 16 bits × 10 MHz = 160 Mbps. This explanation accounts for standard operational parameters for PC Cards, demonstrating why this figure is accurate. The other options reflect measurements that do not pertain to the throughput of a PC Card; for instance, Gigabits per second, wattage, and pin counts are relevant to different contexts such as data rates or power consumption, but not to the specific throughput calculation of a 16-bit bus in a PC Card.
