Learn how files can be compressed using both lossy and lossless methods, where lossy compression permanently removes data (e.g., lowering resolution or sample rate) and lossless compression reduces file size without losing any data (e.g., through run-length encoding).

Quick explanation

Learn how files can be compressed using both lossy and lossless methods, where lossy compression permanently removes data (e.g., lowering resolution or sample rate) and lossless compression reduces file size without losing any data (e.g., through run-length encoding)

• This point belongs to Data storage and compression, especially Data storage and compression outcomes.
• You need to be able to learn how files can be compressed using both lossy and lossless methods, where lossy compression permanently removes data (e.g., lowering resolution or sample rate) and lossless compression reduces file size without losing any data (e.g., through run-length encoding).
• The key ideas to know are Understand.
• Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
