- 14 parts of a knowledge based systemKnowledge base
Rule base
Inference engine
Human computer interface - 2Knowledge-baseWhere data & information, retrieved from experts in a particular field, is stored.
- 3Rule-baseContains the rules that must be applied to the data in the knowledge-base.
- 4Inference engineSoftware which uses the rules in the rule-base to search through the knowledge-base.
- 5Human Computer Interface (HCI)Allows for data or queries to be input and results to be output.
- 6Purpose of Operating systems# Control hardware though systems software
# Provide platform for applications to run on, dealing with any issues
# Provides user interface with operator to allow user to hardware communication
# Handles communications with protocols
# Handles translation of code with compiler
# Uses utility programs to carry out system housekeeping - 7Batch OSTakes large amounts of data in identical format, and processes it when suitable, such as when no one is around. Mainly used for payrolls in businesses.
- 8Real time OSProcessing is done quickly enough to influence that in the real world. Usually found in booking systems and computer gaming.
- 9Single-user OSAccess to system restricted to one user at a time. Each user is allocated with rights and user files are kept separate.
- 10Multi-user OSHandles multiple users at a time. Uses round robin scheduling, flags and priorities.
- 11Multi-tasking OSA multi-user OS that allows any user to run many tasks simultaneously.
- 12Network OSMany users, share devices and software. Mainly used in local are connection (LAN).
- 135 types of user interfaceForms
Menus
GUIs
Natural language interface
Command line - 14Data capture formsSeparate prompt & response fields for number of inputs. Uses drop downs and text boxes. Ensures that data is collected properly and nothing is missed.
- 15Menu based interfaceSeries of options that lead to further different menus, until target information is available. Quick and easy to use, and restricts user to appropriate data. Mainly used in tourist information systems.
- 16Graphical User interfaceUses icons, windows, frames, pointers and menus to extend functionality and application range for relatively experienced users.
- 17Natural language interfaceMainly used in expert systems, this allows the user to user human syntax, though simplification of a query is required.
- 18Command line interfaceRequire user to write single instruction lines for the computer to carry out. User must know available commands, that are appropriate for what he or she wants. Very powerful, but only for those who are experience with this type of system.
