Detailed explanation-1: -The 8086 has eight more or less general 16-bit registers (including the stack pointer but excluding the instruction pointer, flag register and segment registers).
Detailed explanation-2: -The registers inside the 8086 are all 16 bits. They are split up into four categories: General Purpose, Index, Status & Control, and Segment. The four general purpose registers are the AX, BX, CX, and DX registers.
Detailed explanation-3: -The registers found on the 8086 and all subsequent x86 processors are the following: AX, BX, CX, DX, SP, BP, SI, DI, CS, DS, SS, ES, IP and FLAGS. These are all 16 bits wide.
Detailed explanation-4: -The 8086 can generate 16-bit I/0 address, hence it can access 216 = 65536 I/0 ports. 5. The 8086 provides fourteen 16-bit registers. 6.
