4.1 IFS H/W Infrastructure

In the following picture a user uses some type of input technology such as a keyboard. The computer then starts processing the information. The processing technology used for processing the information is called the CPU or Central Processing Unit. The CPU is divided into two parts which are called the Control Unit and the Arithmetic Logic Unit. The part of the CPU used in this picture would be the Control Unit because the Arithmetic Logic Unit deals with mathematical functions. The CPU transforms the letters into machine language. Machine language consists of binary code. In America, we use the ASCII method based on the English alphabet. The binary code consists of bits and bytes. Bits are the individual 1s and 0s in the code. Bytes are a collection of bits used to form a character such as the H in hello. The system unit then stores the information binary code in the physical box that houses all of the electrical components of thee computer. After the information is stored it is then displayed using output technologies such as a monitor or projector.
