Machine code is the only form of program instructions that the computer hardware can understand and execute directly. All other forms of computer language must be translated into machine code in order to be executed by the hardware. Machine code consists of many strings of binary digits that are easy for the computer to interpret, but tedious for human beings to interpret. Machine code is different for each type of computer. A program in machine code for an Intel x86-based PC will not run on an IBM mainframe computer, and vice versa.
The actual machinery - wires, transistors and circuits is called hardware; the instructions and data are called software. All general purpose computers require the following hardware components: (i) Central Processing Unit (CPU): The ‘brain’ of the computer, the component that actually executes instructions. (ii) Memory : It enables a computer to store, at least temporarily, data and programs. (iii) Input device : Usually a keyboard or mouse is used to read data and programs into the computer. (iv) Output device: A display screen, printer, etc.
