实际上,数字信息就是通过磁性介质(如硬盘、光盘等)来记录信息的。与传统的纸张、照片等记录方式相比,它的稳定性很高,信息不会受自身介质和外界环境的干扰。只要磁性介质不损坏,数据将永远保存。另外,数字信息能够借助计算机使其自身的应用形式更加灵活,从而体现出自身更大的价值。虽然数字化为人们的生活提供了很多便利,但由于在当前的社会生活中,传统的模拟信息形式(例如纸张、照片、胶片等)仍
In fact, digital information is through magnetic media (such as hard disk, CD-ROM, etc.) to record information. Compared with traditional paper, photos and other recording methods, its stability is high, the information will not be subject to its own media and the external environment. As long as the magnetic medium is not damaged, the data will be saved forever. In addition, digital information can be used by computers to make their own application form more flexible, thus reflecting their greater value. Although digitization offers many conveniences to people’s lives, as traditional forms of simulated information (such as paper, photos, film, etc.) are still present in current social life
