Digital Technology – Definition, History and Examples

DIGITAL TECHNOLOGY

Digital Technology is defined as ” The branch of scientific knowledge that deals with the development and practical use of digital devices, systems, and methods.”

According to Merrian-Webster ” Technology is the application of knowledge to the practical aims of human life or to changing and manipulating the human environment. Technology includes the use of materials, tools, techniques, and sources of power to make life easier or pleasant and work more productive. Whereas science is considered with how and why things happen, technology focuses on making things happen.”

Digital technology is an electronic technology that generates, stores and processes data in terms of two states: true and false or 0s and 1s. Each of these states is referred to as a bit. Digital information is represented in binary code(a combination of 0 and 1), which represents words and images.

A large amount of information can be compressed on small storage devices with digital technology. Digitization also increases the rate of data transmission. The way of communication, learning methods and working style changes with the invention of digital technology.

History Of Digital Technology

“The word digital comes from the Latin – digitus, finger – and refers to one of the oldest tools for counting.” The development of digital technology began in the mid-twentieth century by American scientists and engineers. They use the mathematical concept developed by German mathematicians, Gottfried Wilhelm Leibniz, who introduced a binary computing system.

The first digital devices invented were Charle’s Babbage analytical engine and the telegraph. The foundation of digital devices was set by Claude Shannon, a Bell Labs mathematician in his 1948 article, “A Mathematical Theory of Communication.”

The digital revolution began between the late 1950 and 1970 changed the way humans communicate, now via computers, cell phones, and the internet. During the 1980s the analog devices such as vinyl records and cassette tapes were replaced by optical compact discs.

The digital communication network started using enhanced fiber optics in the early 1980s. In 1998, commercial digital television broadcasts premiered in the US.

By the early 2000s, digital technology changes the way of photography by recording color and light intensities with pixels. Also, digital compression of images and videos was achieved by the Joint Photographic Expert Group(JPEG) and the Moving Picture Expert Group(MPEG) codes.

12 Examples of Digital Technology

Digital technology has completely transformed almost every aspect of life latterly, including workplace, travel, entertainment, banking sector, shopping, communication and many more.

Although many services and products have been developed associated with the internet, we have many more on the pipeline such as teleportation, interstellar travel, etc. Here the list of examples of digital technology with a short description.

  • GPS for navigation.
  • Embedded functions such as alarm clock, stopwatch, timer, etc.
  • Embedded memory.
  • Hardware or software-based QWERTY keyboard.
  • Wireless synchronization.

3. Geolocation

Geolocation is the identification or estimation of the real-world geographic location of a device such as smartphones, GPS devices, radar sources, or interconnected computers. This becomes possible with the combination of satellite and digital technology, such as mapping technology. Google, Facebook, and Twitter have also stepped into the world of geolocation. Friends are capable of finding our location and companies to promote business with GPS technology.

4. Blogs

Blogs are similar to websites that are seen across the web written by an individual or small group of people. They are interactive and updated on a regular basis, unlike websites.

5. Social Media and Instant Messaging

Social media can be defined as a tool that allows us to keep in touch with friends and family. It also allows users to explore carrier opportunities and to approach the customer, retain and sell products and services. Instant messaging apps such as messenger, Viber, WhatApps allows user to send and receive messages in real-time all because of internet.
