The Contemporary Computer Age
Ed-Eng 106 – Technology in Language Education
Computer Age is also known as:
Information Age
Digital Age
New Media Age
http://en.wikipedia.org/wiki/Information_Age
When we talk about Computer When we talk about Computer Revolution in the Contemporary age, Revolution in the Contemporary age,
this matters alway confronts the picture this matters alway confronts the picture of the world today:of the world today:
• Boundless Connectivity• Fast and Wide Range of
Accessibility • Multiple Tasking Management• Time Efficiency• Hyper Productivity• MegaLibrary• A Changing Reality• Information Overdrive
• As the years pass by so quickly Computers transformed and developed in different forms (gadgets, appliances etc.) to cater the needs of the advancing worlds.
• Computers Change the Way we Understand Reality.
• The use Computer is indeed a life changing experience.
• Household of today without even a single computers is considered primitive.
Five Generations of Computer
First Generation (1940-1956)
Vacuum TubesVacuum TubesFirst generation computers relied on machine language, the lowest-level
programming language understood by computers, to perform operations,
could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on
printouts.
First Generation (1940-1956)
Vacuum TubesVacuum Tubes• The UNIVAC and ENIAC computers are
examples of first-generation computing devices.
First Generation (1940-1956)
Vacuum TubesVacuum Tubes
• UNIVAC (Universal Automatic Computer)
First Generation (1940-1956)
Vacuum Tubes
• Eniac (Electronic Numerical Integrator And Computer)
Second Generations (1956-1963)
TransistorsTransistorsThe transistor was far superior to the vacuum tube, allowing computers to
become smaller, faster, cheaper, more energy-efficient and more reliable than
their first-generation predecessors.
Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast
improvement over the vacuum tube.
Second Generations (1956-1963)
Transistors• Second-generation computers still relied
on punched cards for input and printouts for output.
Third Generation (1964-1971)
Integrated Circuits• The development of the integrated circuit
was the hallmark of the third generation of computers.
• Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers.
Third Generation (1964-1971)
Integrated CircuitsIntegrated Circuits• Instead of punched cards and printouts,
users interacted with third generation computers through keyboards and monitors and interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory.
• Computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors.
Fourth Generation(1971-Present)
MicroprocessorsMicroprocessors• thousands of integrated circuits were built
onto a single silicon chip.
• from desktop computers and into many areas of life as more and more everyday products began to use microprocessors.
• small computers became more powerful
Fourth Generation(1971-Present)
Microprocessors• They could be linked together to form
networks which eventually led to the development of the Internet.
• Fourth generation computers also saw the development of GUIs, the mouse and handheld devices.
Fifth Generation (Present and Beyond)
Artificial Intelligence • still developing• advance applications are
tantamount• Parallel processing and
superconductors are being utilize to create an artificial intelligence a reality
• the use of quantum computing and molecular nanotechnology is rapidly changing the face of modern computers.
Computer Technology has become an integral part of our everyday life. A separation of these technical innovations would not come without adverse effects.

Top Ten Computer Trends for the 21st Century
According to Institute for Global Futures
Computers will become:1. powerful extensions of human beings designed
to augment intelligence, learning, communications, and productivity.
2. Intuitive—they will “learn,” “recognize,” and “know” what we want, who we are, and even what we desire.

According to Institute for Global Futures
3. Computer chips will be everywhere, and they will become invisible-embedded in everything from brains and hearts, to clothes and toys.
4. Computers will manage essential global systems, such as transportation and food production, better than humans will.

5. Online computer resources will enable us to download applications on-demand via wireless access anywhere and anytime.
6. Computers will have digital senses-speech, sight, smell, hearing-enabling them to communicate with humans and other machines.

According to Institute for Global Futures
7. Neural networks and other forms of artificial intelligence will make computers both as smart as humans, and smarter for certain jobs.
8. Human and computer evolution will converge. Synthetic intelligence will greatly enhance the next generations of humans.

9. Human and computer evolution will converge. Synthetic intelligence will greatly enhance the next generations of humans.
10. As computers surpass humans in intelligence, a new digital species and a new culture will evolve that is parallel to ours.
Challenges Brought by the Computer Age
Humans are expected to do more
Diminishing Realistic Activities
Ubiquitous Connectivity
Instantaneous Access to Unlimited Stores of Information
Skills and Knowledge Needed in a world transformed by Technology
Humans are expected to do more than what a computer can do.
