Answer 2

Question ---✓

what is the size of the address bus and the data bus in the 8086?

Answer ---✓

All internal registers, as well as internal and external data buses, are 16 bits wide, which firmly established the "16-bit microprocessor" identity of the 8086. A 20-bit external address bus provides a 1 MB physical address space (220 = 1,048,576).

Data width: 16 bits

Address width: 20 bits

Instruction set: x86-16

Co-processor: Intel 8087
