Which of the following is the best statement to describe the function of the data bus on a microprocessor system ? The data bus is a one-direction output, that outputs data to the correct address. The data bus is a two way traffic highway for data to travel to and from the microprocessor to memory. The data bus is the main output to carry the correct control signals to the right I/O device. The data bus is an output only to carry the correct memory address to the memory chips.

On a typical microprocessor, a distinct I/O address is used to refer to the I/O data reg- isters and a distinct address for the control and status registers in an I/O controller for a given device. Such registers are referred to as ports. In the Intel 8088, two I/O in- struction formats are used. In one format, the 8-bit opcode specifies an I/O operation; this is followed by an 8-bit port address. Other I/O opcodes imply that the port ad- dress is in the 16-bit DX register. How many ports can the 8088 address in each I/O addressing mode? .
An instruction is stored at location100 with its address field at location 110. The address field has the value 300. The value at location 200 is 300, at 300 is 400, and at 400 is 500. Draw a memory diagram to describe this data. Evaluate the effective address and the operand, if the addressing mode of the instruction is (i) Direct (ii) Indirect, and (iii) Immediate. explain in detail.
