Difference between 80186 and 80286 and 80386 and 80486 and pentium
Answers
80286 Microprocessor has Data bus width of 16, Addressed Memory size of : 16M, Clock speed is higher and hence some instructions are executed in as little as 250ns, 80286 does not have multiplexed address/data bus lines.
80386 Microprocessor has 32-bit data bus and 32-bit memory address, It addresses up to 4G bytes of memory, 80386SX: address 16M bytes of memory, 80386SL: address 32M bytes of memory, 80386SLC: address 32M bytes of memory.It contains internal cache memory which allowed it to process data at higher rates
80486 Microprocessor has Data Bus Width: 32 bit, Address bus: 32 bit, Memory Size: 4G +16K cache, The 80486 architecture has been upgraded such that half of its instructions are executed in 1 clock cycle instead of two clock cycles. It has 80386 like microprocessor and 80387 like a numeric coprocessor.
Answer:The Intel 80186 is an improved version of the 8086 microprocessors. 80186 is a 16-bit microprocessor with 16- bit data bus and 20-bit address bus.
