A brief history of computers
The history of computers is a long and fascinating one. The development of computers over time has led to the amazing devices we know and use today, capable of processing enormous amounts of data quickly and accurately, and performing complex tasks with ease.
The earliest computers, known as mechanical computers, date back to the early 19th century and were driven by steam power. These huge machines were largely used for business and scientific calculations, and were far too cumbersome for everyday use.
In 1936, the first electrical computers were built, and over the next few decades ever more advanced models were created. By the 1950s, computers had become capable of storing, processing and using large amounts of data, thus giving birth to the era of data processing.
Growth in computer technology was further fueled by the development of the internet in 1969, and subsequently by the creation of the personal computer (PC) in 1981. PCs continue to be refined and improved, with powerful processors, vast storage space and advanced connectivity and software making them even more capable than ever before.
The portability of computers became infinitely more advanced in the 1990s, with the creation of laptop computers, tablets and even mobile phones, offering us the convenience of being able to connect with others and carry out online tasks from anywhere in the world.
In recent years, a new era of computing has emerged, with cloud computing and artificial intelligence applications rapidly becoming a part of everyday life. We now harness the power of computer networks to enhance the way we do business, collaborate, shop and play.
From mathematics and engineering applications to leisure activities, computers in all their forms have revolutionised how 21st century people interact and communicate with each other, and changed the way society is organised and run. In the more than 200 years since the invention of the mechanical computer, our world has become a lot simpler, more efficient and more fun because of the amazing machines we have come to rely on.
