How Computers Work with Information
From Information to Computation
Bits and bytes
Computers store information using bits, which are tiny units that can be or . Groups of bits form bytes and larger data types such as text, images, audio, and numbers.
Why AI needs data
AI systems learn patterns from examples, so they need data in a form the computer can process. For example, a photo becomes numbers, and a sentence becomes encoded symbols or vectors.
Think of it this way
A computer does not see a cat the way a human does. It sees numbers representing color, shape, and location patterns.
Common data types in AI
| Data type | Example |
|---|---|
| Numbers | Temperature readings |
| Text | A customer review |
| Images | A photo of a dog |
| Audio | A spoken sentence |
What is the basic unit of information in a computer?
A bit is the smallest unit and can represent or .
