4.1 IFS/HW Infrastructure


This diagram displayed above describes how the Information Infrastructure works.  In the diagram, it shows us that when we input data or information via keyboard or mouse (input technologies), it becomes processed by the ALU or the Arithmetic Logic Unit that calculates/compares data, and then it becomes output and then it gets stored in the registers (internal memory) which we can store in your secondary drive (junk drive).   The data is then stored by bits, bytes and so on.  A bit is the amount of information that can be stored in by a digital device.  8 bits make up one byte, 1000 bytes equals 1 kilobytes, and it goes on and on.

It can allow us to input data, however, the control unit (that is part of the cpu) organizes which function it will do in order one by one.  When we input words or data, the computer doesn't understand it and it will convert into its machine language.  Machine language is otherwise known as binary code which is made up as 0s and 1s that make up the data that we input.  This falls under ASCII or the American Standard Code for Information Interchange.
