Meaning, Examples, and Classification of Computers by Size: Mini and Micro Computers 🖥️📏

  1. Mini Computers 🏠:
    • Imagine a small house (mini computer) that helps a family with everyday tasks.
    • Examples: Cash registers in a store or a special computer at home managing household activities.
  2. Micro Computers 🐜:
    • Picture a tiny ant (micro computer) that can do clever things despite its size.
    • Examples: Your tablet or laptop that you can carry around, helping you with games, learning, and fun!

Classification by Size:

  • Big to Small Order: Mainframes (like a castle for big tasks) → Mini Computers (like a small house) → Micro Computers (like a tiny ant).
  • Everyday Comparison: Just like you have big, medium, and small toys, computers also come in different sizes to do different jobs!

So, mini computers are like small houses, and micro computers are like tiny ants, each doing special things in their own size! 🏠🐜
