- 1What 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.
- 2What is the formula for throughput?- throughput = clock speed * width
- 3What 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 - 4What is a half, full and simple duplex?
- 5SATA 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. - 6What is a bottleneck?- A bottleneck is a component or resource which limits the end-to-end throughput.
- 7If 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
