hello,
protected mode can use a 32-bit data path.
hope this helps you

Real mode -16bit Protected mode -32bit
Real mode uses 16 bit data path while protected mode uses 32 bit data path.
In real mode, the data path typically uses 16 bits for operating. This means that the CPU can process 16 bits of data at a time and access up to 1 MB of memory, as real mode is based on the architecture of the original Intel 8086 microprocessor.
In real mode, the effective memory address is the same as the linear, or physical, memory address. The segment register operates by specifying the base of a 64kb region of memory, each region overlapping the other by 16 bytes. In protected mode, the effective address is translated by the page table which provides a larger region size and more memory addressibility. The segment register, a/k/a selector, selects the particular page table to use.
A set of wires or light guides that allow data to flow in parallel rather than in serial mode. The wider the channel path, the more data that flow over it.
SIMMs have a 32-bit data path.
mode field
mode means path, the way in which light travel, in the fiber means angle in multi mode fiber light can travel in more then one angle so it is called multi mode fiber. but in single mode fiber there is dedicated path or single path through which light beam/source can travel.
The width of a data bus is referred to as the data path size. An example would be a 16 bit bus can transmit 16 bits of information
The width of the data path in bits
no answear of the particular of this path
