Master the Art of Data Compression

Data compression is the process of reducing the size of data by reducing the number of bits while retaining its meaning.

The advantages of data compression include reducing storage needed, reducing transmission cost/latency/bandwidth.

The purpose of data compression is to reduce the size or volume of data.

<p>The two observations are: 1. In an optimum code, symbols that occur more frequently will have shorter codewords than symbols that occur less frequently. 2. In an optimum code, the two symbols that occur least frequently will have the same length.</p> Signup and view all the answers
