From Computers to the Internet: A Brief History of Computing

Image
  Computers are everywhere and they are getting more powerful every day. But where did these complex machines come from? Where are they going? And what exactly is the Internet? These questions may seem simple, but there’s a lot more to computing than you might think. Culturally speaking, we live in a world of computers. They’ve infiltrated almost every corner of our lives—from our cell phones to the cars we drive to the televisions we watch. The computer has become one of the most important inventions of all time, and its impact on human communication and interaction continues to grow and evolve. In this blog post, we take a look at how computers have evolved over time, beginning with their origins in the 1950s up through today’s modern-day internet-connected world. The 1950s: From Vacuum Tubes to Transistors The history of computers can be traced back to the late 1940s, when the first generation of programmable computers emerged.

Data Data could be a assortment of raw, unorganised facts and details like text, observations, figures, symbols and descriptions of things etc. In alternative words, information doesn't carry any specific purpose and has no significance by itself. Moreover, information is measured in terms of bits and bytes – that are basic units of knowledge within the context of store and process. Information Information is processed, unionised and structured information. It provides context for information and permits deciding. as an example, one customer’s sale at a eating house is information – this becomes data once the business is in a position to spot the foremost common or least common dish.
