Definitions
› Information technology (IT) is the application of
computers and telecommunications equipment to store,
retrieve, transmit and manipulate data, often in the
context of a business or other enterprise
› According to the Information Technology Association of
America, Information Technology is define in the business
context as "the study, design, development, application,
implementation, support or management of computerbased information systems"
IT Areas of Importance
› Business
› Education
› Finance
› HealthCare
› Security
Advantages and Disadvantages
Advantage
›
Increased globalization
›
Cheaper, easier and faster communication(Skype, Social media)
›
More cost effective Businesses(Streamlining business)
›
Bring Business Nearer the people(e- commerce)
›
Creation of new jobs (Programmers/software developer, systems design/analyzers,
hardware design, and web designers etc.)
Disadvantages
›
Rise in unemployment
Contributions of Physics to the Information Age
Computers
The first electronic digital computer was built in the basement of the
physics department at Iowa State University in 1939 by Professor
John Atanasoff, who had a Ph.D. in theoretical physics from the
University of Wisconsin, and his physics graduate student Clifford
Berry.
The second electronic digital computer, also proposed and designed
by a physicist, was completed in 1945. This computer, called the
ENIAC, was largely based on Atanasoff' s pioneering work.
The Transistor:
This was discovered in 1947 by young physicists (John
Bardeen, Walter Brattain and William Shockle) at Bell
Laboratories in New Jersey. This gave birth to
amplification using semiconductor
And this garnered them the Nobel Prize in 1956 and
opened the way to the telecommunications revolution and
the information age.
The World Wide Web:
In the 1980s, the thousands of physicists at CERN Particle Physics Laboratory in
Geneva needed a better way to exchange information with their colleagues working
in different universities and institutes all over the world.
To meet this need Tim Berners-Lee, a graduate from Oxford University with 1st
class Honors in Physics, invented the World Wide Web at CERN in 1990.
Along with creating the first web browser and web server, he developed the
software conventions that are key to the Web's usefulness, with acronyms like URL
(uniform resource locator) and HTTP (hypertext transfer protocol).
Lasers:
In 1954 the first microwave laser was built by physicist Charles Townes. While the
first optical laser was built in 1960 by physicist Theodore Maiman.
