  Intel 8086
The 8086 (officially called iAPX 86) is a 16-bit microprocessor chip designed by Intel in 1978, which gave rise to the x86 architecture.
Shortly later the Intel 8088 was introduced with an external 8-bit bus, allowing the use of cheap chipsets.
Intel bubble memory was on the market for a while, but faded away as better and cheaper memory technologies arrived.

 Intel 8086 - Definition of Intel 8086 by Webster's Online Dictionary
The Intel 8088 was a version with an eight-bit external data bus.
The Intel 8086 was based on the design of the Intel 8080 and Intel 8085 (it was source compatible with the 8080) with a similar register set, but was expanded to 16 bits.
A later version, the Intel 80386, expanded the design to 32 bits, and "fixed" the segmentation, but required extra modes (suppressing the new features) for compatibility, and retains the awkward architecture.

 INTEL 286
The introduction of the Intel 286 processor originally featured in the IBM AT class computers should have solved the small vs. large memory model problem and let multi-tasking multi-user systems develop.
Observers of the time noted that MicroSoft which had only single tasking software and Intel were working pretty closely together at the time, and it was Digital Research who was ready to storm the market with a multi-tasking Dos but was unable to do so because of an 'I gotcha' in the i286 instruction set.
Intel engineers left this instruction out on purpose, believing that once one had gone to the protected mode, it was irresponsible to return to the real mode, and that doing so would only lead to inherently unstable applications.

 Intel History - The Processor Emporium (UK)
Intel was one of the pioneering Microprocessor manufacturers when it created the 4004 processor in 1971.
The Intel 8086/8088 range of processors were based upon Complex Instruction Set Computing (CISC) which allows the number of bytes per instruction to vary according to the instruction being processed.
The architechture pioneered by Intel has become known as "x86" due to the early naming system where processors were called 8086, 80186 (not used in PC's), 80286, 80386, and 80486.

 Olympus MIC-D: Integrated Circuit Gallery - Intel 8088 Microprocessor
Intel's first venture in 16-bit computing, the 8086, was not related to the previous silicon electronic devices (4004, 8008, 8080).
The 8088 was Intel's first really successful CPU because it was adopted by IBM for their PC and XT models and by most XT-class clones.
During its fledgling years, Intel had to have other, more established semiconductor manufacturers produce its chips like the 8088 since computer manufacturers such as IBM did not want to bet their entire personal computer line on an unproven entity.

 I'm Mac and I'm Proud!
Intel is notorious for creating buggy processors and the company is years behind IBM and Motorola in implementing copper interconnect and SOI.
Intel became the semiconductor giant it is today at least in part by accident rather than by the strength of its technology.
Clearly one must give Intel some credit for taking advantage of the opportunity it was given and successfully marketing its product; however if the success of semiconductor makers were determined by engineering prowess alone, like the inventor of gun powder, Intel probably might have been just a footnote in history.

 8086 Microprocessor
The 8086 is a 16-bit microprocessor with a 16-bit data bus and is implemented in N-Channel, depletion load, silicon gate technology, and packaged in a 40-pin dual in-line packages.
The logic 1 voltage level of the 8086 is compatible with that of most standard logic families, but the logic 0 level is not.
Because the 8086 buses are multiplexed and most memory and I/O devices aren’t, the system must be demultiplexed before interfacing with memory or I/O. Demultiplexing is accomplished by an eight-bit latch whose clock pulse is obtained from the ALE signal.

 4.3 A History of Software Development for the x86
The 8086 CPU, and it smaller sibling, the eight-bit 8088, was happily raking in its portion of the microprocessor market and Intel naturally assumed that it was time to start working on a 32-bit processor to replace the 8086 in much the same way that the 8086 replaced the eight-bit 8085.
When Intel introduced the 80286 and, later, the 80386, the only way to take advantage of their extra addressing capabilities and the larger segments of the 80386 was to operate in a so-called protected mode.
Intel also hired lots of software engineers and began funding research into topic areas like speech recognition and (visual) pattern recognition in order to drive the new technologies that would require the new instructions their Pentium IV and later processors would offer.

Intel themselves have been running an advertising campaign in the USA which stresses you should always choose an 80386SX over an 80286 or earlier microprocessor.

The Intel 8088 (released shortly afterwards) was essentially the same chip, but with an external 8-bit data bus, allowing the use of cheap chipsets.
However, the 8086 design was expanded to support full 16-bit processing instead of the fairly basic 16-bit capabilities of the 8080.
The most influential microcomputer of all, the IBM PC, used the Intel 8088, a version of the 8086 with a narrower memory bus.

 r_harvey - 8086 Processor Registers
Programmers unanimously agree: while Intel 8086 family processors are well designed and versatile, there are just not enough CPU registers (a remnant of their '70s heritage).
The 8086 processors are little-endians, which means the least significant bytes of any number fall at lower memory addresses.
Intel 32-bit processors widen the standard registers to 32-bits, add two new segment registers, and a host of useful new general-purpose instructions.
