What is the bus data path width of PCI 1.0?

  1. 64 bit

  2. 32 bit

  3. 16 bit

  4. 128 bit

The correct answer is: 32 bit

The bus data path width of PCI 1.0 is 32 bit. PCI 1.0 was the first version of the Peripheral Component Interconnect (PCI) bus standard, released in 1992. It had a 32-bit data path width, meaning it could transfer 32 bits of data at a time between components. Option A, 64 bit, is incorrect because this is the bus data path width for PCI 2.0, released in 1993. Option C, 16 bit, and Option D, 128 bit, are also incorrect as they are not the bus data path widths for any version of PCI. Therefore, if we are specifically referring to PCI 1.0, the correct answer is B, 32 bit.
