Digital Data

Answer 9

Digital data is information that is represented using a series of discrete values, usually 0s and 1s. These values are known as “bits” and they form the basic building blocks of digital data.

For example, when you type a message on your computer, each letter you type is converted into a series of 0s and 1s, which can be stored and processed by the computer. Similarly, when you take a digital photo, the image is captured as a series of pixels, each of which is represented by a set of bits that describe its color and brightness.

Video and audio files: Multimedia files such as MP4, WAV, and MP3 can be embedded in a web page to provide video and audio content.

Web APIs: Web APIs (Application Programming Interfaces) provide a way for other software applications to interact with a web application and exchange data.

Web resources can be hosted on a web server or served from a Content Delivery Network (CDN), and they can be accessed by users through a web browser. Web developers must carefully design and optimize web resources to ensure that they are fast, responsive, and accessible to users across different devices and network conditions.
