It is my understanding that the 80286 has a 16-bit data bus. This was a doubling of the original 8086/8088 processors.

Size of 8086 address bus?
The 8086/8088 has an internal 20-bit address bus and 16-bit data bus. Externally, the address bus is 20-bits, and the data bus is 16-bits for the 8086 and 8-bits for the 8088.The data bus in the 8086 is 16 bits in size, while the address bus is 20.
What is the difference between 8086 and 8088 microprocessor?
The difference between the 8086 and the 8088 is that the 8086 has a 16 bit data bus and that the 8088 has an 8 bit data bus. Both processors are the same 16 bit processor, and both have a 20 bit address bus. The 8086 is twice as fast as the 8088 in terms of data transfer rate on the bus for the same bus clock speed.
What is the size of address bus in 8086?
The address bus in the 8085 is 16 bits wide.
Why 4 bit address bus is grounded?
The data bus in the 8086 is 16 bits in size, while the address bus is 20 (16bits would only address 64KB of memory, an extra 4 bits allows to address the total of 1MB, this is done trough segmentation of the memory). To form a multiplexed of data bus and address bus, four bits of 8086 address bus are grounded.
Why does microprocessor 8086 has 16 data bus and 20 address bus why aren't they equal?
The 8086 has 16 data bus lines and 20 address bus lines because that is how Intel designed it. They wanted a processor that was more powerful than the 8085, which has an 8 bit data bus and a 16 bit data bus, so they increased both bus sizes accordingly.
How does 8086 determine wheather instruction is 8 bit or 16 bit?
based on the size of the data bus they determine whether it is a 8 bit or 16 bit . here in 8086 it has 16 bit data bus hence it is called as 16 bit microprocessor
Role of latches in 8086 microprocessor?
for demultiplexing address/data bus
What is the difference between between 8085 and 8086 microprosser?
The data bus of 8085 is 8 bit.Its operating frequency is 3.03 Mhz.Address bus is 16 bit. The data bus of 8086 is 16 bit.Its operating sfrequency is 5 MHZ.Address bus is 20 bit.
Why 8086 was not use IBM PC?
Because IBM wanted to build a computer with an 8-bit data bus. The 8086 and 8088 are the same processor, with the 8086 running on a 16-bit data bus, and the 8088 running on an 8-bit data bus. This allowed IBM to make the most use of older designs that supported 8-bit data buses, such as the 8080, the 8085, and the Z80.
What is DEN in 8086 in microprocessor?
Data enable, signals that bus lines are being used to transfer data
What are speed of buses of Intel boards like 8086 8088?
The Intel 8086 and 8088 motherboards had the system bus speed, which is 5-10 MHz However, the processors for the motherboards had different external data bus widths with the 8088 CPU featuring an 8-bit bus and the 8086 a 16-bit bus.
What is the need of Instruction PointerIP in 8086 microprocessor?
The Instruction Pointer (IP) in an 8086 microprocessor contains the address of the next instruction to be executed. The processor uses IP to request memory data from the Bus Interface Unit, and then increments it by the size of the instruction.
