DC refers to the unidirectional flow of electric charge. Unlike Alternating Current (AC), which periodically reverses direction, DC flows steadily in one direction. This type of current is commonly used in batteries, electronics, and various portable devices. The consistent flow of electricity makes DC ideal for applications requiring stable and reliable power. DC power is also pivotal in renewable energy systems, such as solar panels and electric vehicles, ensuring efficient and continuous energy supply.

DC is the process of reducing the size of digital data to save storage space and improve transmission efficiency. By encoding or transforming data, compression algorithms minimize the amount of space needed to store or transmit information. There are two main types of data compression: lossless, which preserves all original data, and lossy, which removes some data to achieve higher compression rates. Data compression is crucial for managing large volumes of data, reducing costs, and enhancing the performance of digital systems and networks.
