Similar to the x86, the x64, which is also called "x86-64" ( meaning x86-based 64-bit) is also a family of instruction set architecture for computer processors. But, x64 has 64-bit CPUs and an operating system rather than the 32-bit system which belongs to x86. It is officially k...

x86 (also known as 80x86[2] or the 8086 family[3]) is a family of complex instruction set computer (CISC) instruction set architectures[2] initially developed by Intel based on the Intel 8086 microprocessor and its 8088 variant. The 8086 was introduced in 1978 as a fully 16-bit extension...
This ambuiguity of x86--meaning 64-bit processors that can also run 32-bit code--is mainly for/due-to Operating Systems that run on 64-bit processors, but allow the user of said OS to run 32-bit software. Windows makes use of this with a feature called "compatibility mode". ...
The ARM processor vs. x86 architecture arose from the highly competitive environment of the early 1980s, after IBM introduced the IBM Personal Computer, which used an Intel-produced x86 chip. A British company called Acorn Computers wanted to compete in that market. ...
The ping command is used to check the physical connection of the network when the communication between a user computer and the hosts in the network is interrupted. Format ping IP address of a host Example Check the physical connection between the current host and the host whose IP address is...
When purchasing the SOM-128-EX module from DMP, its ROM chip comes preinstalled with an Arduino-like bootloader which is useless to us. Also, the "crossbar" is configured for using the module with the 86Duino Zero/One boards - meaning its default pin layout is completely different from wha...
The third difference between theADD-immediate and the standardADDinstruction is the meaning of theREGfield in theMOD-REG-R/Mbyte: Since the instruction implies that the source operand is a constant, and MOD-R/Mfields specify the destination operand, ...
