Data can be in the form of numbers, text, images, or sound. All data is stored digitally as binary numbers (bits and bytes) inside computers. Numbers are stored directly as binary, while text, images, and sound are converted to binary codes. For text, ASCII codes represent characters. Images use pixel values for colors. Sound samples loudness at intervals. Data is processed into meaningful information when organized and stored in databases, which are managed by database administrators. Digital information systems combine hardware, software, databases, and networks to collect, store, and process data into useful information for businesses.
