Data CDs are compact discs specifically designed to store digital information, such as documents, images, and software. They can hold up to 700 megabytes of data, making them a convenient option for backing up files or transferring information between computers. Data CDs are read by CD drives, which can be found in many computers and some standalone devices. To create a data CD, users typically use software that allows them to select files and burn them onto the disc. Once burned, the data is stored in a format that can be accessed by compatible devices. CD drives and burning software are essential tools for this process.
