What are the differences between 80286 and 80386 microprocessor?

80236	80386
(i) The Intel 80286 is a 16-bit microprocessor that was introduced on 1 February 1982.	(i) The Intel 80386 mis a 32-bit microprocessor introduced in 1985.
(ii) It also marketed as the i APX 286 and often called Intel 286.	(ii) It also known as i386 or just 386.
(iii) It was the first 8086 based CPU with separate, non-multiplexed address and data buses and also the first with memory management and wide protection abilities.	(iii) The 80386 instruction set, programming model, and binary encodings are still the common denominator for all 32-bit x86 processors, which is termed the i386-architecture, x86, or IA-32, depending on context.
(iv) The 80286 microprocessor is an advanced version of the 8086 microprocessor that is designed for multi user and multitasking environments.	(iv) The 80386 microprocessor is an enhanced version of the 80286 microprocessor and includes a memory management unit is enhanced to provide memory paging.
(v) The 80286 addresses 16 M Byte of physical memory and 1G Bytes of virtual memory by using its memory-management system.	(v) The 80386 has a physical memory size of 4GBytes that can be addressed as a virtual memory with up to 64TBytes.
