The 8086 is a 16-bit microprocessor with a 20-bit address bus, allowing it to address up to 1 MB of memory. It is characterized by its two main functional units: Branch/String: JMP , CALL , RET , LOOP , MOVS , CMPS

Operands are located in registers (e.g., MOV AX, BX ).

Contains the offset address of the next instruction. 3. Addressing Modes

Handles external bus operations, including fetching instructions, reading/writing data from memory, and maintaining a 6-byte instruction queue (pipelining).
