From Computers to the Internet: A Brief History of Computing

 

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. The computers of this era, however, were very different from the computers we use today, and they were built using vacuum tubes. During the 1940s, scientists had already made huge strides in their understanding of vacuum tubes, which were invented in the early 1900s. Vacuum tubes were used in a wide variety of applications, including radios, televisions, and computers. In computers, vacuum tubes were used to carry out calculations, store data, and control the flow of electricity in and out of the computer. And some of the biggest computers of the era, such as the ENIAC, were vacuum tube based.

The 1960s: Going Solid State

The 1960s marked a turning point in the history of computing as scientists began to explore the use of transistors—which, unlike vacuum tubes, don’t require a vacuum to operate. Transistors, which had been invented in the late 1940s, were smaller and more efficient than vacuum tubes. In the beginning, the only computers built with transistors were very large, mainframe computers. But by the last decade of the decade, smaller computers had made their way onto the market. These computers were known as minicomputers, and they were the first computers built with transistors.

The 1970s: The Arrival of Microprocessors

As the decade of the 1970s unfolded, computer designers began to explore the idea of combining a computer’s central processing unit (CPU) with its memory. By the end of the decade, the first microprocessors had hit the market. While minicomputers were capable computers, they were still too large and expensive for many businesses. Microprocessors, which integrated the CPU and memory into one unit, were smaller and cheaper than minicomputers and could be used to power smaller computers.

The 1980s: The PC Revolution Begins

The 1980s saw the advent of yet another type of computer: the personal computer, or PC. The first PCs were large, bulky machines that were used mostly in businesses and universities, but as the decade progressed, they became smaller and more powerful. Eventually, they were powerful enough to be used in homes. By the late 1980s, PCs were so popular that they threatened to put minicomputers out of business. Most businesses that used minicomputers eventually switched over to PCs.

The 1990s: Internet Becomes Mainstream 

Concurrently with the rise of PCs, engineers continued to make improvements to the Internet. In the early 1990s, the Internet was still fairly limited in its reach and accessibility, but by the end of the decade, it had become much more mainstream. By the turn of the century, businesses that had once been reluctant to use the Internet were more comfortable with the idea of online storefronts, and people were spending more and more time online.

2000 - present: Smartphones and the Internet of Things

The early 2000s saw a surge in the development of handheld devices, such as smartphones, that were connected to the Internet. Throughout the decade, handheld devices continued to get more powerful, and by the end of the decade, computers were no longer limited to the desktop. They could be found in cars, watches, and other everyday items. The Internet of Things refers to the connection of everyday objects to the Internet. These objects include household appliances and fitness trackers, as well as cars, refrigerators, and pretty much anything else that you can think of.

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.
