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

How many type of instructions does the 32-bit Intel 8086 have?
The Intel 8086/8088 is not a 32 bit machine. It is a 16 bit machine. It has 72 instruction types.
What is the difference between 8080 and 8086?
The major difference between the 8085 and the 8086/8088 is that the 8085 is an 8 bit computer, and the 8086/8088 is a 16 bit computer.
What represent 8086?
8086 means its a 8 bit processor and 86 is its model number
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 8086 processor?
it primarily running as a 16 bit processor..so it is so called as 8086
Write a sequence of instruction to exchange two register contents using stack in 8086 processor?
To exchange two registers, say the BX and CX registers, in the 8086 using the stack, you can use...PUSH BXPUSH CXPOP BXPOP CX... Of course, this is for 16 bit operation. If you want 8 bit operation, you will need to do more than that, because stack operations are always 16-bit operations.
Why 8088 is slower than 8086?
The 8088 is slower than the 8086 because the 8088 is running an 8-bit bus, while the 8086 runs a 16-bit bus. The two processors are the same, 16-bit processors, but the 8088 requires twice as many memory accesses to do the same amount of work as the 8086.
Difference between 8086 and 80386?
There are several differences between the 8086 and the 80386. Two notable differences: 1.) the 8086 is a 16 bit computer, while the 80386 is a 32 bit computer, and 2.) the 8086 does not support virtual addressing while the 80386 does.8086 is 8 bit processor and 80386 is 16 bit processor
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 xlat in 8086?
XLAT instruction converts the contents of AL register into a number stored in a memory table,this instruction perform the direct table look up technique often used to convert one code to another.An XLAT instruction 1st add the contents of this AL to BX to form a memory address within a data segment .It then copies the contents of this address into AL.This is the only instruction that adds an 8 bit number to 16-bit number.
What it the size bit address for 8085 and 8086?
128Kb
What is the advantages and disadvantages of 8086 microprocessor?
the advantages of 8086 microprocessor over 8085A microprocessor is that 1)it is a 16 bit microprocessor 2)the disadvantages in 8085A microprocessor like low speed,limited number of registers,low memory addressing capability,less powerful instruction set have been overcome in 8086 registers
