Data compression is a field of study that focuses on reducing the size of data in order to save storage space, increase transmission speed, and improve efficiency in data processing. This involves using various algorithms and techniques to encode data in a more compact form without losing any important information. Data compression is commonly used in applications such as file compression, image and video compression, and multimedia streaming. The goal of data compression is to minimize the amount of data that needs to be stored or transmitted while maintaining the quality and integrity of the original information.
