Digital Data is a type of computer-based information that is encoded into a particular form for use in computer-based activities. It is typically stored, retrieved and manipulated as part of a system of electronic communication. Digital data typically is represented in a range of formats, including numerical, symbolic, text, audiovisual and multimedia.
Digital data can be used to represent any type of information, including documents, images, audio or video files, numerical data, and compressed data. For example, digital data can be used to represent a printed document in an electronic form so that it can be stored, read and printed by an electronic device. Digital data also includes database files. Database files are sets of records that contain information about particular topics.
Digital data also includes machine-readable data, which are data that are in a form that is recognized by computers. Machine-readable data includes raw data obtained from sensors, such as audio recordings, photographic images, thermocouples, and readings from an accelerometer. It also includes data that has been processed into a form that is suitable for computers, such as databases that store information about people or products, and webpages that contain information about particular topics.
Digital data can be stored and manipulated by computers in a variety of ways. The most common way to store digital data is on a computer hard drive or other removable media. Digital data can also be sent over networks, such as the Internet, or stored on cloud-based servers.
Digital data is an important part of modern digital technology. It is used in virtually every aspect of society, from science and engineering to telecommunications and entertainment. As the amount of digital data grows, so does the need for efficient ways to store and manage it.
