What is Gigabyte?

The gigabyte is a unit of digital data equal to 1,000 megabytes (one billion bytes). It is the most familiar data unit in daily life, used for smartphone storage (64 GB, 128 GB, 256 GB), mobile data plans (3 GB, 20 GB per month), and app sizes. A high-definition movie is roughly 4 to 5 GB, and a smartphone photo is about 3 to 5 MB, so one GB can hold roughly 200 to 300 photos.

What is Byte?

The byte is the fundamental unit of digital data, consisting of 8 bits. One byte is enough to represent a single ASCII character such as a letter or digit. In UTF-8 encoding, a Japanese character typically requires 3 bytes. All larger data units (KB, MB, GB, TB) are built upon the byte. It serves as the basic addressable unit in computer memory and storage systems.
