How? Explain in detail.

In general, a data bus is broadly defined.

The first standard for data bus was 32-bit, whereas newer 64-bit systems can handle much greater amounts of data.

Other data bus widths include 1-bit, 4-bit, 8-bit, and 16-bit.

In 8051 Microcontroller = 8 bit.

What about 8051 Microcontroller? it is 16bit or 8bit.

In 8085, Data bus is multiplexed with address bud ie, AD0-AD7.

So 8 bits.

Raja Ruban said:   8 years ago
8085 is an eight bit data bus.

But what if I choose "D" as my answer am wrong and why?

AD0-AD7 i.e. Lower bank.
AD8-AD15 i.e. Higher bank.

So, each bank contain 8 bit. That's why 8 bit is used in data bus.
8085 - 8 bit.
8086 - 16 bit.

Option B is correct answer.

AD0-AD7 i.e. Lower bank.
AD8-AD15 i.e. Higher bank.

So, each bank contain 8 bit. That's why 8 bit is used in data bus.

Its depend on how many wordlength of processor. 8085 has 256 word length so databus is 8 bit.
