DESCRIPTION OF THE PRESENTATION
1st slide:

Original use to compute, hence name computer

Need to solve complex engineering and arithmetic problems without using slide
rule or a mechanical adding machine

Problem keeping track of intermediate results and using them properly in later
steps

1st computer designed by Charles Babbage

1st computer built by Konrad Zuse in Germany

Automatic calculator would require 3 things – a control, a memory and a
calculator for the arithmetic
2nd slide:

Military funded research to build new computers

John Maulchy and John Eckert designed ENIAC (Electrical Numerical Integrator
And Calculator)

Vacuum tube computers, faster than paper tape or punched cards

Needed a computer to calculate artillery firing tables and for the settings for
different weapons under different conditions for improved accuracy

Never used during war by military, mainly for calculations during research of
hydrogen bomb and for predicting things like the weather or random number
studies

War was over by time it was finished, but still provided useful in other areas like
the building of the hydrogen bomb, weather prediction and random number
studies
3rd slide:

Transistors were next step in moving toward the modern computer we have today

Faster than vacuum tubes and easier to maintain

Acted as a transmitter converting sound waves into electronic waves, and resistor,
controlling electronic current
4th slide

IBM already big in punch card technology

Produced 1st commercial transistorized computer – previous computers had been
used by government agencies and military

Released a series of general purpose computers called the IBM 700 series

Came out in late 1950s, development slowed after production of IBM 7090

Fastest computer of its time and considered the super computer of its time

IBM has controlled the history of computers for the majority of the past half
century
5th slide:

Next major development came in 1981, when IBM released it’s 1st personal
computer, called IBM PC

In discussions with Microsoft to create an operating system for the PC 
Microsoft products like Word and PowerPoint

Used the integrated circuit which was a large number of tiny transistors on a
circuit board

Development of Integrated Circuit lead to most of the technology we have today
in computers
6th slide:

Wrap up slide

Whatever society has needed or wanted from computers has influenced growth
and development

Society has need to be “in the know” at all times and on the go so laptops
developed to meet the needs of society

Great increases in speed, storage, and memory

Increased networking, speed in Internet

Widespread use of CD-RW
