MACHINE LANGUAGE M
A computer does not work with words, or even with familiar base-10
numbers. Instead, the machine uses combinations of ones and zeros.
These are the two binary states, also represented by on/off, high/low, or
true/false. Data in machine language, if written down, looks like a string
of ones and zeros, such as 0110100100. This can be represented pictorially
by a graph as shown in the illustration.
When a computer operator writes a program, or a person issues a
command to a robot controller, it is done in a high-level language. This
must be converted into machine language for the computer. The computer
output is likewise translated from machine language into whatever high-
level language is used by the programmer or operator.
