ELECTRONIC COMPUTING MACHINES

Before describing electronic machines it is useful to consider computing machines in general. There are two main classes of computing equipment known respectively as analogue and digital machines. In analogue machines numbers are represented by physical quantities such as the angular rotation of a shaft of the current in a resistor, the numbers being the measures of those physical quantities. Examples of analogue machines are the plan ammeter, the differential analyses, resistance network, etc.

Because they are dependent on the accuracy of physical measurements, analogue machines are strictly limited in regard to the precision of which they are capable. Even with a well designed planimeter, for example, it is difficult to calculate areas to more than four significant figures. For most physical problems this does not constitute a severe restriction and a far more serious limitation of analogue machines is that they are, in general, special purpose devices.

It is known that digital machines, on the other hand, work directly with numbers in digital form and are capable of performing exactly the fundamental operations of arithmetic, addition and subtraction, and usually also multiplication and division.

THE CENTRE OF DIGITAL COMPUTING SYSTEMS

The central processing unit (CPU) or central processor is the centre of any digital computer system since it coordinates and controls the activities of all the other units and performs all the arithmetic and logic processes to be applied to data. All program instructions to be examined should be held within the CPU, and all the data to be processed should be loaded first into this unit. The general processor is known to have three separate hardware sections: an internal or main memory, the arithmetic and logic unit, and a control unit. ~ 1500
