A wireless keyboard may use industry standard Bluetooth radio communication, in which case the receiver may be built into the computer.
The instructions are usually part of an executable program, often stored as a computer file and executed on the processor. The x86 instruction set has been extended several times, introducing wider registers and datatypes as well as new functionality.
