Detailed explanation-1: -It supports two modes of operation, i.e. Maximum mode and Minimum mode. Maximum mode is suitable for system having multiple processors and Minimum mode is suitable for system having a single processor.
Detailed explanation-2: -There are two operating modes of operation for Intel 8086, namely the minimum mode and the maximum mode. When only one 8086 CPU is to be used in a microprocessor system, the 8086 is used in the Minimum mode of operation. In a multiprocessor system 8086 operates in the Maximum mode.
Detailed explanation-3: -The addressing modes provided by the 8086 family include displacement-only, base, displacement plus base, base plus indexed, and displacement plus base plus indexed. Variations on these five forms provide the 17 different addressing modes on the 8086.
Detailed explanation-4: -AD0-AD15 and A16 – A19. 8086 is designed to operate in two modes, Minimum and Maximum. from memory and queues them in order to speed up instruction execution.
Detailed explanation-5: -2) The 8086 has a 16-bit data bus, so it can read data from or write data to memory and ports either 16 bits or 8 bits at a time. The 8088, however, has an 8-bit data bus, soil can only read data from or write data to memory and ports 8 bits at a time.
