Any media that is encoded in a format that requires a machine to read. Digital media is made, distributed, read, enhanced, and kept on a digital electronic device. Therefore, digital is any data represented with many digits.
On the other hand, the media refers to a method of communicating information. Hence, digital media is any information that is broadcast to us through a screen. Examples are text, audio, and a video that is transmitted over the internet.
Furthermore, digital media examples are software, digital image, digital video, web pages and websites, social media, and e-books. They act in contrast to print media such as newspapers, magazines. When combined with the internet, digital media cause disruptive innovation in journalism, education, more.
Digital media also bring new challenges to intellectual property laws. Practical digital multimedia distribution and streaming became possible through innovation in data compression. The most significant compression method is the discrete cosine transformation (DCT).
The DCT is an algorithm which was discovered in 1972 by Nasir Ahmed. Another video coding standard is the MPEG video format. It first appeared in 1991.
Background of digital media
Charles Babbage first propounded codes and information by machines in the 1800s. He imagined that codes would send instructions to his Analytical Engine—a machine he built to solve mathematical calculations problems.
The first instruction for calculating numbers on Babbage Machine was written between 1822 and 1823. Ada Lovelace wrote the instructions. Many people believe that Lovelace’s instructions are the first computer program.
There are other old machine-readable media. Examples are the Jacquard Loom weaving machine and Pianolas. Digital media has seen a steady increase in popularity.
In 1986, less than 1% of media storage in the world was digital. However, at the end of 2007, the number has risen to 94%.
Impact of digital media
From the 1960s, storage capacity, as well as computing power, has increased. The main reason for this increase is MOSFET scaling. PCs and smartphones enable millions of people to access, modify, store and share digital media. Electronic devices, such as digital cameras, can create, transmit, and display digital media.
Additionally, the World Wide Web and the internet combine with digital media to transform how we do things like print and share information. The transformation is rapid, widespread that has facilitated a digital revolution. Hence, the transformation has brought a new set of communication skills.
These sets of communication skills are referred to as media literacy or digital literacy. Hence, these communication skills include reading and writing alongside the ability to navigate the internet. Furthermore, the ability to evaluate information sources and create digital content are all part of these communication skills.
Additionally, digital media are easy to copy, store, and share. There is an advantage over print media and other analog technologies. Hence, it has brought changes to several industries.
These industries include publishing, journalism, education, and entertainment business. Core digital media outlets have made the information easy to transmit and share among millions of people.
Digital media has become the future of communication and information sharing. It has allowed individuals to become better in content creation. Hence, it plays a vital role in the cultural and social lifestyles of millions of people worldwide.
Core digital media is the leading way in online marketing and online consumer purchasing platform.
