Sep 19, 2015 · x86 refers to the architectures compatible with intel 386, 486, etc. x32 and x64 are misnomers often used just to mean "32-bit" or "64-bit"

Feb 3, 2013 · What is the difference between x86 and x64 binaries here, we would like to download binaries for Windows 7, Ubuntu 12.04 (32 bit options)

Mar 3, 2014 · I know that x86 means a 32-bit computer/operating system, but what does 86 it's self mean? Shouldn't it be x32? Additionally, what do i386, i586, i686, i986 mean?

Apr 19, 2016 · While reading the Intel 64 and IA-32 Architectures Software Developer’s Manual, the operation section for the LEA instruction (load effective address) uses a calculation called EffectiveAddress(SRC)

For example, after installing Debugging Tools for Windows (x86) on XP, it's found in Program Files but on Windows 7 it's found on Program Files (x86) which means there's no simple way to create a command file that can be distributed across all computers since none of the built-in environment variables consistently point to the 32-bit location ...

OTOH Itanium is a completely different architecture and has no relation to x86-64 whatsoever. It's a pure 64-bit architecture so all normal registers are 64-bit, no 32-bit or smaller version is available. There are a lot of registers in it: 128 general-purpose integer registers r0 through r127, each carrying 64 value bits and a trap bit.

So, as the question states, what is the purpose of CS and IP registers in intel's 8086 I found this explanation: Code segment (CS) is a 16-bit register containing address of 64 KB segment with
