About both units

From

Byte

The byte equals 8 bits — the basic unit of file size and memory. One byte encodes one ASCII character. All file sizes and RAM capacities are quoted in bytes and their multiples (KB, MB, GB, TB).

Real-world: An ASCII character: 1 byte. A short text message: few hundred bytes. Uncompressed photo: few MB.

Gigabyte

The gigabyte equals 1,000,000,000 bytes (SI) or 1,073,741,824 bytes (binary, GiB). Standard unit for USB drives, SSDs, mobile-data allowances and RAM. A 64 GB phone holds about 15,000 photos.

Real-world: Smartphone: 64 GB / 128 GB / 256 GB typical. PC RAM: 16 GB / 32 GB common. UHD movie: 20–50 GB.

Tips & common mistakes

Quick tips

1 byte = 8 bits.
KB, MB, GB are 1000 or 1024 multiples of bytes — check context.
Use bytes (B) for storage; bits (b) for bandwidth.

Avoid these

Confusing byte (B) with bit (b).
Assuming 1 MB always equals 1,048,576 bytes — sometimes 1,000,000.
Mixing file size (bytes) with transfer speed (bits per second).
