It is hard to believe that it has been over 70 years since the first electronic computer was built. In that time, computers have become smaller, faster and more powerful. They are now an essential part of our everyday lives.

Although the basic design of computers has not changed much since 1948, the way they are used has changed beyond recognition. In this essay, we will explore some of the ways in which technology has changed since 1948.

One of the most obvious changes is the way computers are used. In the early days, computers were large machines that filled whole rooms. They were used mainly by scientists and mathematicians for complex calculations. Today, computers are small enough to fit in our pockets and are used by people of all ages for a variety of tasks such as writing essays, playing games and keeping in touch with friends and family all over the world.

The use of computers has also changed the way we work. In the past, most jobs were done by people using manual labor or simple machinery. Today, many jobs involve using computers to do tasks such as word processing, accounting and data analysis. This change has led to a decrease in the number of jobs available for unskilled workers and an increase in the demand for skilled workers who are able to use computers effectively.

The introduction of computers has also made it possible for people to access information from all over the world at the click of a button. In the past, if you wanted to find out about something, you would have to go to a library and look it up in a book or ask someone who might know. Today, you can simply type a question into a search engine such as Google and find out everything you need to know within seconds.

As you can see, technology has changed a lot since 1948 but it is hard to say whether these changes have been for better or for worse. One thing is certain – life would be very different without computers!

The early days of technology

It is hard to believe that it has only been since 1948 that we have seen the amazing advances in technology that we have today. It is even harder to believe that many of the things that we take for granted today, such as computers, smartphones, and even the Internet, did not even exist just a few decades ago. Let’s take a look at how technology has changed since 1948.

One of the most important inventions of the 20th century was the transistor, which was invented in 1947 by John Bardeen and Walter Brattain at Bell Labs. The transistor revolutionized electronics by allowing circuits to be miniaturized, which led to the development of smaller and more efficient devices. This paved the way for the development of integrated circuits in the 1960s, which further miniaturized electronic components and ushered in the modern era of digital electronics.

The first computers were developed in the early 1940s, but they were large, expensive, and used vacuum tubes instead of transistors. In 1948, John von Neumann published a paper outlining his design for an electronic computer called EDVAC (Electronic Discrete Variable Automatic Computer), which used an integrated circuit-like device called a Babylonian tablet. This design became known as the Von Neumann architecture and was used in most computers until well into the 1970s.

The first commercial computers were introduced in 1951 by UNIVAC (Universal Automatic Computer) and IBM (International Business Machines). These computers were still large and expensive, however, and so they were mostly used by government agencies and large businesses. It was not until the 1970s that personal computers began to be developed that were small enough and affordable enough for individual consumers.

In 1957, two engineers working at Sanders Associates, Paul Baran and Donald Davies, independently came up with the idea of using packets to send data over a network. This led to the development of packet-switching networks, which are now at the heart of modern computer networking technologies such as Ethernet and WiFi.

The 1960s saw several important inventions in computer science, including Doug Engelbart’s work on hypertext links (which led to Tim Berners-Lee’s development of the World Wide Web in 1989) and Alan Kay’s work on object-oriented programming (which led to modern programming languages such as Java and Python).

In 1971, Intel released the world’s first microprocessor, the Intel 4004. This invention made it possible to put all of the components of a computer onto a single chip, which greatly reduced both size and cost. This led to the development of personal computers in the 1970s and 1980s that were small enough to fit on a desk or even under it!

The late 1970s sawthe developmentof two important networks: public bulletin board systems (BBSes), which allowed users to exchange messages and files electronically;and Usenet(a decentralized network of discussion groups), which gave rise to online communities such as “newsgroups.” Both BBSesand Usenetwere instrumentalin developingthe online cultureof today.

The 1980s wasa decadeof greatchangein both computingand telecommunications technologies. The inventionof cellular telephonesand cellular networks made it possiblefor peopleto communicateover long distanceswithout beingtied downto a single locationby a phone line. The developmentof ACKNOWLEDGEMENTTECHNOLOGYNetworks(ATN) made it possibleto connectcomputernetworksacross long distanceswithout usingphone linesor other wired infrastructure.And thenew fieldof fiber-optictransmissionopened up new possibilitiesfor high-speeddata transmissionover long distancesas well(see below).

The advent of the internet

The internet has revolutionized the way we communicate, work, and live. It has allowed us to connect with people around the world in ways that were previously unimaginable. It has also transformed the way we access information and learn new things. In short, it has changed the way we live our lives.

The rise of mobile technology

The last seventy years have seen extraordinary changes in the world of technology. In 1948, the first commercially available electronic computer, the Electronic Numerical Integrator And Computer (ENIAC), was unveiled. This massive machine filled an entire room and could perform only the most basic calculations. Today, computers are handheld devices that can perform complex tasks and connect to a global network of information.

The rise of mobile technology has been one of the biggest changes in the last seventy years. In 1948, there were no cell phones, no laptops, and no tablets. Today, these devices are commonplace, and we use them for everything from communicating with loved ones to streaming our favorite movies. This rise in mobile technology has transformed the way we live and work. We can now take our work with us wherever we go, and we can stay connected to our loved ones no matter where they are in the world.

The growth of social media

In recent years, the way people communicate has changed dramatically with the growth of social media. In 1948, the only form of social media that existed was letter writing. Although this was a slower form of communication, it allowed people to keep in touch with friends and family who lived far away. Today, there are many different social media platforms that allow people to connect with anyone in the world instantly. Social media has made it possible for people to connect with each other and share information quickly and easily.

The impact of technology on society

In 1948, the world was a very different place. There were no computers, no cell phones, no internet and no email. People communicated by sending letters through the mail or by using the telephone. Information was not readily available and it took longer to gather data and research information.

Today, technology has drastically changed the way we live our lives. We can now communicate instantly with anyone in the world via email or text message. We have access to more information than ever before and we can research anything we want with just a few clicks of a button. Technology has made our lives easier in many ways, but it has also had an impact on society as a whole.

The future of technology

Back in 1948, the future of technology was a hot topic. The world was just recovering from the devastating effects of World War II, and people were eager to see what the future held.

In the years since then, technology has changed in ways that no one could have predicted. We’ve gone from black-and-white televisions to color, from bulky vacuum tube radios to sleek smartphones, and from room-sized computers to portable laptops.

And it’s not just the hardware that’s changed. The way we use technology has changed too. In 1948, most people didn’t even know what a computer was. Today, we use them for everything from booking plane tickets to sending email.

As we look ahead to the next 70 years, it’s impossible to say exactly what the future of technology will bring. But one thing is for sure: it’s going to be an exciting ride!


Technology has changed significantly since 1948. In that year, the first digital computer, the ENIAC, was invented. This machine was large, expensive, and used vacuum tubes. Today, computers are smaller, cheaper, and more powerful. They use semiconductor chips instead of vacuum tubes.

Other significant changes have occurred in communications and transportation. In 1948, few people had telephones or cars. Today, most people in developed countries have both. Moreover, we can now communicate with people around the world instantly using the Internet. And we can travel quickly and easily thanks to jet airplanes and high-speed trains.
