1) Briefly describe the positive impact of AI in our daily life.

Answer:

AI makes our daily life easier by providing smart solutions like voice assistants, automatic translations, smart recommendations (like YouTube or Netflix), and helping in healthcare and education fields. It saves time and increases efficiency.

Example: Using Google Maps to find the fastest route is a positive impact of AI.

2) Differentiate between supervised and unsupervised machine learning.

Answer:

  • Supervised Learning: In this method, the machine learns with labelled data (data with correct answers given).
  • Unsupervised Learning: In this method, the machine learns from unlabelled data (no correct answers given).

Example:

  • Supervised: Email spam detection.
  • Unsupervised: Customer segmentation based on shopping habits.

3) Describe how computer vision applications help in automation of tasks.

Answer:

Computer vision helps machines see and understand images and videos, automating tasks like facial recognition, quality inspection in factories, and medical image analysis.

Example: Face unlock feature in mobile phones is based on computer vision.

4) Compare the use of Natural Language Processing (NLP) with computer languages for interaction with computer.

Answer:

NLP allows users to interact with computers using human languages (like English or Urdu), while computer languages (like Python or Java) need special coding knowledge.

Example: Using voice commands to search on Google uses NLP.

5) What is a robot? Mention four areas where robots can replace humans that are not mentioned in this unit.

Answer:

A robot is a machine capable of carrying out a complex series of actions automatically.

Four areas:

  • Farming (automatic crop harvesting)
  • Housekeeping (automatic vacuum cleaners)
  • Military (bomb disposal robots)
  • Space exploration (Mars rovers)

6) Is the use of Grammarly AI tool a perfect replacement of manual proofreading?

Answer:

No, Grammarly AI is helpful in finding basic spelling and grammar mistakes but it cannot fully understand the meaning or emotions behind writing. Manual proofreading by humans is still important for best quality.

Example: Grammarly may correct grammar, but a human can improve the style and tone.
