When Did the First Computer Come into Existence? The Evolution of Technology!



Computers are an essential part of modern life, from personal computers and smartphones to the vast supercomputers that power complex scientific simulations. But where did it all start? In this article, we will explore the history of computers, from the earliest automated calculation devices to the powerful machines of today.

The Origins of Computing

The Idea of Automating Calculations

By the second decade of the 19th century, the potential benefits of being able to automate routine calculations were appreciated, and this led to the invention of the first automated calculating device [1].

The Babbage Difference Engine

The first automatic computing engines were invented in the 19th century and were called the Babbage Difference Engine, conceptualized by Johann Helfrich von Müller, a German engineer who sketched a proposed structure for this computer on paper in the late 18th century [6].

The First Computers

The ENIAC Computing System

In 1943, the ENIAC computing system was built by John Mauchly and J. Presper Eckert at the Moore School of Electrical Engineering of the University of Pennsylvania. Because of its electronic technology, it was over 1,000 times faster than any previous computer [2].


Scientists with the Council of Scientific and Industrial Research (CSIR) built Australia’s first digital computer called the Council for Scientific and Industrial Research Automatic Computer (CSIRAC) in November 1949 [4].

IBM 701

IBM publicly introduced the 701 on April 7, 1953, its first commercial scientific computer. This device paved the way for the development of mainframe computers [8].

The Personal Computer Revolution

From Professional Use to Personal Use

In the 1960s, computers evolved from professional use to personal use, and the first personal computer was introduced to the public [9].

The Apple I and II

In 1976, Steve Wozniak and Steve Jobs created the Apple I, the first personal computer with a keyboard and a screen. In 1977, they released the Apple II, which became the first successful personal computer [10].


In 1981, IBM released its first personal computer, the IBM PC, which helped to standardize computer hardware and software [10].

The Modern Era of Computing

The Internet and the World Wide Web

The invention of the Internet and the World Wide Web in the 1990s revolutionized computing and communication, making information more accessible and interconnected than ever before [10].

Smartphones and Tablets

The 2000s saw the emergence of smartphones and tablets, which have become increasingly powerful and ubiquitous, enabling people to access the Internet and computing resources from anywhere [10].


Computers have come a long way since the first automated calculating devices of the 19th century. From large mainframes and desktop computers to personal computers and smartphones, computers have become an integral part of our daily lives. With the advent of the Internet and the World Wide Web, computers have enabled us to access and share information like never before. Smartphones and tablets have made computing accessible to more people than ever before, revolutionising how we work, learn, and communicate.

As computing technology continues to evolve, we can expect to see even more powerful and innovative devices in the future. From artificial intelligence and machine learning to quantum computing and beyond, the possibilities are endless. The history of computing shows us that innovation is key to the development of technology, and we can expect to see even more exciting developments in the years to come.
