What data transfer rate in MB/s can a 32-bit PCI slot handle?

• A. 100 MB/s
• B. 66 MB/s
• C. 133 MB/s
• D. 150 MB/s

Answer: (C)

To determine the data transfer rate a 32-bit PCI slot can handle, it's essential to consider the width of the bus and the clock speed. A standard 32-bit PCI bus operates at a clock speed of 33 MHz. The formula for calculating the theoretical maximum data transfer rate is as follows: \[ \text{Data Transfer Rate} = \text{Bus Width (in bits)} \times \text{Clock Speed (in MHz)} / 8 \] First, we convert the bus width from bits to bytes by dividing by 8 (since there are 8 bits in a byte). So for a 32-bit bus: \[ \text{32 bits} / 8 = 4 \text{ bytes} \] Now, applying the clock speed of 33 MHz to the formula: \[ \text{Data Transfer Rate} = 4 \text{ bytes} \times 33 \text{ MHz} = 132 \text{ MB/s} \] This value rounds to 133 MB/s, indicating that the maximum data transfer rate a 32-bit PCI slot can handle is indeed 133 MB/s. This figure reflects the theoretical limit and is the reason why that

The formula for calculating the theoretical maximum data transfer rate is as follows:

[

\text{Data Transfer Rate} = \text{Bus Width (in bits)} \times \text{Clock Speed (in MHz)} / 8

]

First, we convert the bus width from bits to bytes by dividing by 8 (since there are 8 bits in a byte). So for a 32-bit bus:

[

\text{32 bits} / 8 = 4 \text{ bytes}

]

Now, applying the clock speed of 33 MHz to the formula:

[

\text{Data Transfer Rate} = 4 \text{ bytes} \times 33 \text{ MHz} = 132 \text{ MB/s}

]

This value rounds to 133 MB/s, indicating that the maximum data transfer rate a 32-bit PCI slot can handle is indeed 133 MB/s. This figure reflects the theoretical limit and is the reason why that
