Describe HCI
Allows for data or queries to be input and for the results to be output
Describe the Rules Base
Contains all the rules that can be applied to the knowledge base
Describe the Inference Engine
Software which uses the rules in the rule base and performs searches through the knowledge base
What is a Character Code?
They are the symbols that the computer can use, and each symbol is unique, and they normally determinable by reference to characters on a keyboard. e.g. ASCII or UNICODE
Give two examples of applications that require a character set
> Word Processor
> ATM machine
Explain the use of codes for these applications
Each character requires a unique Binary code. The number of bits to represent the code establishes the size of a byte. For example ASCII uses 8 bits per character. This allows keys to have different characters.
