4. WHAT IS DATA?
Data consists of unprocessed facts
and figures that have no context or
meaning on their own. For example,
numbers, dates, and strings of text.
Raw Facts
Data refers to raw facts,
figures, or information that
can be processed, analyzed,
and interpreted to derive
meaning or insights.
When data is processed, organized,
or structured in a way that adds
context and meaning, it becomes
information.

YOUTUBE
University of Jhang
• Let’s say you want a list of the top 10 most popular videos on
YouTube, manually.
• You would need to have all 145 million videos printed out, along
with the number of views. • Assume one person could maybe look
through 8,000 videos in a day and find the most viewed ones in
their list • How would you do this?
