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.

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.

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).
