Computers are electronic devices that perform calculations and tasks based on instructions. Early computers from the 1800s were programmed using punch cards and the first electric punch card machine was developed in 1886. By 1944, IBM had developed a large machine that could perform basic math operations and refer to tables, representing an important early development in computers. Effective slide design principles include using colors that are visible together, not typing out entire scripts, and avoiding dizzying transition effects.

2. The Computer System
 An electronic
device that
can
perform tasks
&
calculations
to provide logical
information based
on the instructions
given

3. Brief History of Computers
 Early 1800’s - development of
machines that could be
programmed; controlled by
punch cards
 1886 - punch card machine
run by electricity
 1890 - U.S. Census results
tabulated for the first time
using punch cards
 1944 - IBM & Howard Aiken
developed 50 ft long x 8 ft
high machine that could +, - ,
X, / and refer to tables

4. Effective Slide Design
 Don’t use colours that look
bad on eachother or are
hard to see
 You shouldn’t type
everything that you will say
on the slide
 Don’t use crazy transitions
that could possibly make
the audience dizzy
