| Question | Answer |
| What is the purpose of the Front-side bus? | - The Front-side bus connects the CPU to the chipset that connects the CPU to the rest of the bus architecture. |
| What is the formula for throughput? | - throughput = clock speed * width |
| What is the meaning of the formula? | - Throughput means data rate - In another way, it means the amount of data it can get through from point A to point B correctly. - Clock speed - how fast the bits are being pumped over to the buses - Bus width - Number of bits it can transfer per cycle - If the throughput is high means it has a higher data rate with lesser errors |
| What is a half, full and simple duplex? | |
| SATA or PATA has a higher throughput? | SATA: An SATA connection would have a higher throughput. An SATA connection can achieve a maximum theoretical throughput of 6Gbps as compared to a PATA which can achieve only a maximum theoretical throughput of 1.064Mbps. The reason is because at a higher clock speed, PATA a parallel transfer tends to suffer from time skewing and cross talk. This will result in data loss and a lower throughput data rate. |
| What is a bottleneck? | - A bottleneck is a component or resource which limits the end-to-end throughput. |
| If the clock speed of a bus is operating at 200 MHz, given that it is operating at HALF- DUPLEX with a width of 32 bits, calculate the throughput of the bus in Gbps? | Data rate = clock speed * width = (200*10^6) * 32 = 6.4 Gbps |
