Question: 1 / 525

What is the bus speed of PCI 1.0?

33MHz

PCI 1.0 has a bus speed of 33MHz. This is the default speed set by the specification for all devices connected to the PCI bus. The other options, 66MHz, 100MHz, and 133MHz, are incorrect because they are not the designated bus speeds for PCI 1.0. These speeds correspond to newer versions of PCI, such as PCI 2.0, 3.0, and 4.0, respectively. Therefore, A is the only correct answer for the given question.
