In the digital world, data is measured in bytes and their multiples. These units help us estimate the size of files and storage capacity.

📐 Basic Units

Unit Symbol Size
Bit b Smallest unit of information (0 or 1)
Byte B 8 bits
Kilobyte KB 1,024 bytes (≈ 1,000)
Megabyte MB 1,024 KB
Gigabyte GB 1,024 MB
Terabyte TB 1,024 GB

🗂️ Examples of Data Sizes

Type of File Approximate Size
A 40-page plain text document (no images) 200 KB
A JPEG photo with 5 megapixels 2 MB
A 3-minute MP3 music file 3 MB
A full movie 1 GB

These estimates can vary depending on compression, quality settings, and file format. Understanding file sizes helps in managing storage, downloads, and transfers more efficiently.
