      What is the difference between x86 and 32 bit?
      x86 is the 32-bit ISA implemented in all Intel and AMD processors. There is also x86-64 which is the 64-bit extension of the x86 ISA, it is sometimes called x64 and amd64 by software. 32-bit Windows is a flavour of the OS that runs on that 32-bit x86 ISA.

      How many bytes is x86 instruction?
      Note: you can have as many prefix bytes as you want in a instruction but x86 instructions are limited to 15 bytes long. (Some cisc architectures such as Vax have some instructions which are 53 bytes with up to 6 operants). thank you. that was a very good explanation.

      Why is 32 bit x86?
      “x86” is simply a reference to the Intel family of microprocessors and while it is true they were not 32-bit until the 80386, it’s used as a reference to the 32-bit processors while x86_64 refers to the 64-bit Intel processors of today.

      What are the x86 registers?
      x86 registers. There are 9 registers in x86: EAX, EBX, ECX, EDX, ESI, EDI, EBP, ESP and EIP. These are mostly derived by prefixing E (Extended) to their 16 bit equivalents. EAX: The accumulator. This register typically stores return values from functions. EBX: This register is typically the pointer to the base of an array.
