Interesting facts:
- A human brain's memory capacity is estimated to be around 2.5 petabytes. That’s enough to store roughly 3 million hours of TV shows
- Facebook processes over 4 petabytes of data per day (in 2023) while Ggoodle processes roughly 20 PT daily
- Training large AI models (like ChatGPT) requires petabytes of data
- Global internet traffic exceeds 100 petabytes per second.
Interesting facts:
- Because computers use binary (1 KB = 1,024 bytes) but storage manufacturers use decimal (1 KB = 1,000 bytes), a "1 KB" file in marketing may be smaller in real computing terms.
- In the early 1990s, a simple website page was about 30 KB. Today, most basic websites are 1–5 MB (1,000 times larger), due to images, scripts, and videos.
- The Apple II (1977) had only 4 KB of RAM—barely enough for a tiny program. Early personal computers stored programs in kilobytes, whereas today, even small images are often megabytes in size.
- A kilobyte can store about 1 second of low-quality audio, while an MP3 song is typically 3–5 MB
