Definition

1. Noun:

   • The process of restoring compressed data to its original form: In computing, the act of converting data that has been made smaller (compressed) for storage or transmission back into its full, usable format for display or processing.

Examples of Usage

  • Faster decompression algorithms allow for quicker loading of high-resolution images.

Advanced Usage

  • Proper decompression stops are essential to prevent decompression sickness in scuba diving.
• "Decompression chamber": A sealed compartment used to simulate high pressure for treatment or to allow a person to adjust slowly to normal atmospheric pressure.
