About both units

From

Terabyte

The terabyte equals 10¹² bytes (SI) or 2⁴⁰ bytes (binary, TiB). Used for large drives, NAS units, and big-data contexts. A 1 TB drive holds around 250,000 photos or 500 hours of HD video.

Real-world: Desktop HDD: 1–20 TB. Typical NAS: 4–48 TB. Cloud-storage plans: often 1–2 TB.

Kilobyte

The kilobyte equals 1000 bytes (SI) or 1024 bytes (binary). In drive marketing and networking, KB = 1000 B. In RAM and some OS contexts, KB = 1024 B. Use KiB when you specifically mean 1024 bytes.

Real-world: Simple text file: 1–10 KB. Webpage HTML: 20–200 KB. Email: typically under 100 KB without attachment.
