5/2/2012 Laith fahim from Iraq,Baghdad 80386 (or 80386DX) is internally and externally a 32-bit microprocessor with a 32-bit address bus. It is capable of handling physical memory of up to 4 GB (232).Virtual memory was increased to 64 terabytes (246) .
80386SX has a 16-external data bus and a 24-bit address bus which gives a 16MB (224) of memory . that is makes more cheaper from the 80386DX

What is the difference between the Intel 80286 and the Intel 80386?
Comparison between micro processor Intel and Motorola
What does the numbers 8086 mean?
The numbers 8086 most often refer to the first generation of 16 bit computer processor chips. These where made by Intel. Later generations where named 80186, 80286, 80386, and 80486 often dropping the 80 prefix.
The virtual memory addressing capability of 80386 is?
NONE! The 80186 was an advanced version of the 8086 but did not include support for virtual memory. It had a 64K physical address space. The 80286 was the first Intel CPU to support virtual memory but it's capabilities were limited.
Difference between 8086 and 80386?
There are several differences between the 8086 and the 80386. Two notable differences: 1.) the 8086 is a 16 bit computer, while the 80386 is a 32 bit computer, and 2.) the 8086 does not support virtual addressing while the 80386 does.8086 is 8 bit processor and 80386 is 16 bit processor
What IC 80386 is?
The 80386 was a third generation version of the 8086/8088 microprocessor. The second generation was the 80286, adding protected mode. The 80386 added 32 bit mode, virtual 8086 mode, and flat 32 bit protected mode.The 80386 fixed the problem of the 80286 where existing object code was not compatible in protected mode because the meaning of the segment registers changed. The 80386 allowed the operating system to run in protected mode while presenting the process with a virtual 8086 environment where the segment registers worked as before. This was a stop-gap measure that worked until the full implementation of a true 32 bit flat memory model operating system and software.
Why was it important to move from the successful 80286 to 80386?
I assume your speaking of the Intel 80286 and the 80386 computer processors. This series of processors are the reason we call "32-bit processor architecture" x86. Anyway, the importance of moving from 80286 to 80386 lies in the fact that the former could only execute 16-bit code, and the the latter supported 32-bit code. In layman terms, the 80286 could only natively calculate numbers up to 65,536-1 (65.536) without implementing advanced software to allow caclulations of numbers greater than that. The 80386, however, was capable of mathematically manipulating numbers up to 4,294,967,296-1 (or 4,294,967,295). This innovation allowed many programmers to write programs more easily without the need for them to implement extra functions to allow them to process large numbers. For this same reason, we now use 64-bit processors, and will eventually move on to 128-bit and 256-bit in the future, however, when this will happen is a matter of when hardware designers create and software programmers decide to support such a system.
What is the difference between 8086 and 8088 microprocessor regarding there pin diagram?
The differences are given below: 80286 1. Low data bus width (16 bit) 2. Returning from protected mode to real mode is hard and complicated. 3. Small RAM/Memory 80386 1. High data bus width (32 bit) 2. Easy for 80386 3. Big RAM / Memory (Real memory = 4GB and virtual memory= 64TB)
What was Intel's first microprocessor?
The 4004 was Intel's first microprocessor and the world's first single chip microprocessor. For the first PC as we know it (the 1981 IBM PC), it was the 8088, following with 80286, 80386, 80486 and then the Pentium line.
What are 10 microprocessors?
Ten microprocessors are the 4004, 4040, 8008, 8080, 8085, 8086, 8088, 80286, 80386, and 80486.There are many more, and this list only included some of the Intel microprocessors, in mostly historical order.
Difference 8085 and Pentium IV processor?
4004 8008 8086 and series go on 80286 80386 80486 Pentium 1 Pentium 2 Pentium 3 Pentium 4 Dual core Core 2 duo Core 2 Quad Upto CoreI7 So basically in a long time period Pentium 4 is an improvement on 8085 and basically today micro code of all these processor is of 8085
What is the word size of the Intel 80386?
The Intel 80386 is a 32-bit processor.
What is the evolution of Intel computer?
It starts with the 4004 chipset (4 bit) and 8008 microprocessor (8 bit). The successor of the 4004 was the 4040, but this architecture was a dead end. The successors of the 8008 were the 8080, 8085, 8086, 8088, 80186, 80286, 80386, 80486, Pentium, etc. including the current multicore microprocessors. IBM chose to base their PC on the 8086 and 8088, then as successive newer microprocessors were developed new versions of the IBM PC used those microprocessors. Intel also produced many specialized microprocessors and microcontrollers including some RISC microprocessors (e.g. i860, i960). Current Apple Macintosh computers also use the latest Intel multicore microprocessors.
