What is the main purpose of using data compression?

The main purpose of using data compression is to optimize storage space. When data is compressed, its size is reduced, which allows users to store more information in the same physical or digital space. This is especially important for saving disk space on hard drives or optimizing bandwidth when transmitting files over the internet. Compressed files take up less room and can be transmitted or stored more efficiently, leading to improved performance and resource management.

While other options mention different aspects such as file size, file structure, and file security, they do not relate directly to the primary motivation behind data compression. Compression does not inherently increase file size, and while it may simplify file management in a way (like grouping multiple files into a single compressed archive), that is a secondary benefit rather than the main purpose. Additionally, data compression does not directly enhance file security; although compressing files into a secure archive can add a layer of protection, the primary aim of compression remains focused on storage efficiency.
