Systems Life Cycle
Once the system is operational, this phase involves monitoring its performance, addressing issues, and making improvements as needed.
System Maintenance
What does the term "Intellectual Property" refer to?
Intellectual Property (IP) refers to creations of the mind, such as inventions, literary and artistic works, designs, symbols, names, and images used in commerce.
JPEG / JPG use what kind of file storage?
Lossy
all of the data, facts and conditions about the expert's particular subject.
Knowledge base
What term refers to a presentation that incorporates various forms of media, such as text, images, audio, and video?
multimedia presentation
This phase of the systems life cycle involves identifying the need for a new or improved system and determining its feasibility.
Systems Analysis phase
Define: software piracy
The unauthorized copying, distribution, or use of software without proper authorization or license from the copyright holder.
This term refers to reducing the size of a file for storage or transmission purposes.
File compression
This uses the facts and rules from the rules base and applies it to the knowledge base when selecting an answer to the user's query.
This technology enables users to make voice calls using the internet instead of traditional phone lines.
VOIP
This phase focuses on building or acquiring the necessary hardware, software, and infrastructure components for the system.
System Implementation
Explain the term "public domain" in the context of Intellectual Property.
Public domain refers to works that are not protected by copyright and are freely available for anyone to use, modify, and distribute without restriction.
DAILY DOUBLE
Which file format is commonly used for saving text documents with basic formatting, making them easily readable on virtually any device?
It provides the reasoning abou the information in the knowledge base. It assists the user to understand the contents of the knowledge base and also the reasoning process.
Explanation system
What term describes a tool or system individuals use to manage and forecast their personal finances, including income, expenses, savings, and investments?
personal financial model
In this phase, the system is evaluated to determine its effectiveness, efficiency, and overall success in meeting business objectives.
System Evaluation
DAILY DOUBLE!
What is fair use in copyright law?
This file type is commonly used for storing tabular data in a plain text format.
Expert systems that can automatically learn from experience and improve their performance over time use this type of learning technique
Machine learning
What are three common challenges or problems encountered when using computer modeling techniques?
This phase involves carefully recording and detailing all aspects of the system, including its design, functionality, and user manuals.
System Documentation
Give 1 pro and 1 con of a licence key
Pro:
Makes piracy harder.
Not as financially difficult and slow as using legal threats
Cons:
User friction - Adds an inconvenience to users who legally purchased the software.
User support - Will require staff to help users struggling with licence key activation.
Licence keys can still be worked around through various means
This file type is suitable for storing images with support for transparency and lossless compression.
PNG or GIF
Give 2 common issues with expert systems
Knowledge Acquisition: Acquiring and codifying domain-specific knowledge from human experts can be time-consuming and challenging, particularly when dealing with tacit or implicit knowledge that is not easily articulated.
Knowledge Maintenance: Expert systems require regular updates and maintenance to ensure that the knowledge base remains current and relevant. Updating the system with new information or expertise can be labor-intensive and costly.
Overfitting: Expert systems may become too specialized or overfit to the training data, leading to poor generalization performance on new cases. Balancing specificity with generality is essential to ensure the robustness of the system.
Transparency and Explanation: Expert systems often operate as black boxes, making it challenging for users to understand how decisions are reached. Providing explanations for system outputs and decision-making processes is crucial for user acceptance and trust.
Give 3 disadvantages of using robots in manufactoring
1. Cannot make independent decisions
2. Machine learning is not yet at the stage where they can smoothly handle situations they weren't coded for
3. High initial cost
4. Can cause hurt workplace morale if it leads to letting go of staff
5. Robots can break down and will require repairs so you will need technicians to repair and a plan to continue work while the robot is being repaired.
