Byte Size Hierarchy
- Order of bytes from smallest to largest: Kilobyte, Megabyte, Gigabyte, Terabyte, Petabyte, Exabyte.
Byte Definitions
- Kilobyte (KB): Contains one thousand bytes.
- Megabyte (MB): Contains one million bytes.
- Gigabyte (GB): Contains one billion bytes.
- Terabyte (TB): Contains one trillion bytes.
- Petabyte (PB): Contains one quadrillion bytes.
- Exabyte (EB): Contains one quintillion bytes.
File Size Examples
- Kilobyte Example: A file size of 2.5 KB represents a small text file.
- Megabyte Example: A .jpeg image typically ranges from 10 to 100 KB, showing that it can fall within the kilobyte or megabyte range in size.
- Gigabyte Example: A .mov or .mp4 video file has a rate of approximately 15 MB/min or about 1 GB/hour.
Media Compression Rates
- MP3 Files: Typically consume about 1 MB per minute of audio.
- Multimedia files vary significantly in size, influencing storage needs and data transfer rates.
