In technical terms it is a computer program that contains the knowledge and analytical skills of one or more system, related to specific subject.

This was developed by researchers  in artificial intelligence in 1960s and 1970s and commercially in 1980s.
Artificial Intelligence is the study of a system that perceives its environment and takes actions which maximizes its chances of success.

It usually works asking serial number of questions to the end-user and some of the for itself
Example: A system is developed for making a Coffee.
It will ask several amount of questions
Like- Did the costumer entered the money or not? (itself)
What amount of sugar?
What amount of milk?
Do you want black coffee or the normal one?
Is the cup placed on the right position? (itself)
Is the cup filled to its maximum level? (itself)
Did the person take the cup or not? (itself)
And will repeat the same procedure for others.
-------------------------------------
Provides consistent answers for repetitive decisions, processes and tasks
Holds and maintains significant levels of information
Encourages organizations to clarify the logic of their decision-making
Never "forgets" to ask a question, as a human might

Expert Systems are programs that mimic the intelligence of a human expert in a specific field of knowledge or experience.

They are often used when experts are not easily available, or are too expensive, e.g. to give medical advice.

This works by using a database of stored information on computer about medical conditions. An expert gives the computer a set of rules to use when making a diagnosis.

ICT is probably one of the more easier A*'s out there,seeing how we did the practicals with ease. that was 60% overall. Tomorrow is a 40%. If we score 3/4 of it right,Woohoo!xD
so goodluck to all. and hopefully the paper wont be hard!:)

Expert systems usually have the following features:
Knowledge base: containing all facts and rules concerning the topic of study

Inference Engine: This is a program which gradually works towards a solution of the user's problem using the experts knowledge and user replies.

User interface: Enabling the user to communicate effectively with the computer systemm, using the appropriate terminology and question styles

The following steps are requires to create an expert system:

• Date is collected from experts
  Knowledge base is designed/created
  Inference engine is designed/created
  Input screen is desiigned/created
  Output format is designed/created

Application which involve the use of expert systems:

• Medical diagnosis
  Mineral Prospecting
  Car engine fault diagnosis

(Whew!! Hope that helps!:D)

E.g. A network that has several star networks linked together is a hybrid network
