What is data transfer instruction set?
The data transfer instructions move data between memory and the general-purpose and segment registers, and perform operations such as conditional moves, stack access, and data conversion.
What is instruction set with example?
An example of an instruction set is the x86 instruction set, which is common to find on computers today. Different computer processors can use almost the same instruction set while still having very different internal design. Both the Intel Pentium and AMD Athlon processors use nearly the same x86 instruction set.
What is instruction example?
The definition of instruction is the act of educating, giving the steps that must be followed or an order. An example of instruction is someone giving another person detailed directions to the library. Any of the sequence of steps to be followed, as in doing, using, or operating something.
