The Evolution of
Computers
From room-sized machines to devices that fit in your pocket —
eighty years of remarkable transformation.

2.

Introduction
Today, computers are everywhere. We use them at school, at work and at home.
However, computers have changed dramatically over the last eighty years.
The goal of this presentation is to explain the main generations of computers,
describe how computer technology has developed and discuss what computers
may be like in the future.
History
The first four generations of computers
Present
The current state of modern computers
Future
The fifth generation and beyond
The presentation will take about four or five minutes. At the end, I will be happy to
answer your questions.

1940S – MID 1950S
The First Generation
The first generation existed mainly from the 1940s to the middle of the
1950s. These computers used vacuum tubes to process information.
They were extremely large, expensive and unreliable. They also used a
lot of electricity and produced a great deal of heat.
One famous example was ENIAC. It occupied a large room and
weighed about thirty tons. The first-generation computers were
programmed using machine language, which was very difficult for
people to understand.

The Second Generation
MID 1950S – 1960S
The second generation appeared in the middle of the 1950s and
continued into the 1960s. Vacuum tubes were replaced by transistors.
Transistors were much smaller, faster and more reliable than vacuum
tubes. Computers of this generation used less electricity and produced
less heat. They were also easier to maintain.
During this period, programming languages such as FORTRAN and
COBOL were developed. These languages made programming more
convenient and accessible.

Easier to Use
Keyboards and monitors became more common, which made
computers easier to use.

The Fourth Generation
1970S – PRESENT
The fourth generation started in the 1970s with the invention of the microprocessor. A microprocessor placed
the central processing unit on a single chip.
This development led to the creation of personal computers. Computers became smaller and more
affordable, so ordinary people could use them at home, at school and at work.
During this generation, laptops, computer networks and the Internet also became increasingly important.
Modern desktop computers, laptops, tablets and smartphones are generally considered products of the fourth
generation.

The Present: Modern Computers
Today, computers are much more powerful than the computers of the past. A modern smartphone has more
processing power than many early computers, but it can fit into a pocket.

THE FIFTH GENERATION
The Future
The fifth generation of computers is connected with artificial intelligence and
intelligent systems. These computers are expected to understand natural
human language, solve complex problems and make independent decisions.
In the future, computers may become even smaller, faster and more energyefficient. We may use more wearable devices, smart glasses and intelligent
robots.
Quantum computers may also become important. Unlike traditional
computers, quantum computers use the principles of quantum physics. They
could solve certain problems much faster than today's computers.
The development of computer technology may create challenges
around privacy, cybersecurity and the responsible use of artificial
intelligence.

Summary
1st Generation
1
Vacuum tubes — very large, expensive and difficult to
operate.
2
2nd & 3rd Generation
Transistors and integrated circuits made computers
smaller, faster and more reliable.
4th Generation
3
The microprocessor led to personal computers, laptops
and smartphones.

Present & Future
AI, cloud technologies, quantum computers and intelligent
robots are shaping what comes next.
The history of computers shows how quickly technology can develop. Computers have changed from huge machines occupying entire
rooms into small and powerful devices that we can carry in our pockets.
