It all started with the ABASCUS

Lets take a walk through History

• 6 B.C. The ABACUS was an early computing
  instrument.
• 1642 Blaise PASCAL is credited with building the
  first digital calculating machine.
• 1671 Gottfried Wilhelm von Leibniz invented a
  computer that was built in 1694. It could add and
  by successive adding and shifting multiply.

5

• 1820 Thomas of Colmar developed the first
  commercially successful mechanical calculator.
• 1823 Charles BABBAGE started construction of a
  full scale difference engine.
• 1890 Herman Hollerith and James Powers introduced
  punched cards while working for the U.S. Census
  Bureau.
• 1930 Howard AIKEN and IBM engineers collaborated
  on the Harvard Mark 1.

• 1942 John P. Eckert, John W. Mauchly built a
  machine called Electrical Numerical Integrator
  and Calculator (ENIAC)
• 1945 John Von Neumann undertook a theoretical
  study of computation.
• 1947 Random access memory (RAM)
• 1950s Saw the introduction of magnetic-core
  memory and the transistor-circuit.
• 1960s Central Processing Units (CPUs)
• 1970s Minicomputers supplied with software
  packages.

SPREADSHEET

• What is a Spreadsheet ?

8
A spreadsheet falls within the term applications
software which is as diverse as the applications
of computers. Application software is generally
divided into two groups, horizontal and vertical.
9
Vertical applications programs are tailored to
very narrow and specific tasks. A horizontal
program can cut across many application areas
examples are spreadsheets and database programs.
10
A spreadsheet is a computer program designed to
facilitate the manipulation of data. The value
of a spreadsheet lies in the way it automates
processes and saves time.
11
An example of this would be when a user wants to
change a variable and the computer calculates the
effect of the change on the entire
program. Spreadsheets are popular tools in
business, where they speed up and simplify
procedures.

Up until recently the BIG NAMES in Spreadsheet
programs were.
CA SuperCalc
Borland Quattro Pro
As Easy As
15
However today most companies would go for either.
LOTUS 1-2-3
MICROSOFT EXCEL
Excel being the main part of the Microsoft Office
package.

Spreadsheets can be found in Integrated packages
such as Microsoft Works and Coral WordPerfect
Suite but these could be considered as cut down
versions of the Real Thing.
With the modern day spreadsheet it can be the
next best thing to a Desk Top Publishing Package
in that you can add pictures, graphs, text,
lines, shapes, shading and colour.
But the modern day spreadsheet is much more than
that it can deal with complicated calculations
and even form the base for a database
18
Lets look at how the spreadsheet appearance has
progressed over the years.
19
Originally the spreadsheet had a very plain
screen and operated mostly on key strokes which
the operator had to be familiar with in order to
operate the program. Most programs came with a
template which would be placed on the keyboard to
assist the operator. There was very little in
the production of graphs, normally a separate
program was purchased for this purpose. On
screen colours were also limited and at that time
colour printers were not yet readily available.
