2. A spreadsheet is a grid that organizes data
into columns and rows. Spreadsheets make it
easy to display information, and people can
insert formulas to work with the data
It is an application that allows the user to
enter numbers and text into a table with
rows and columns and perform calculations
on them
People use spreadsheet programs to learn
about different kinds of things, and to make
decisions. Spreadsheets are based on
different varieties of subjects
3. The word "spreadsheet" came from "spread"
in its sense of a newspaper or magazine item
(text and/or graphics) that covers two facing
pages, extending across the center fold and
treating the two pages as one large one
4. The main concepts are those of a grid of
cells, called a sheet, with either raw data,
called values, or formulas in the cells.
Formulas say how to mechanically compute
new values from existing values
5. A "cell" can be thought of as a box for
holding data. A single cell is usually
referenced by its column and row
6. value can be entered from the computer
keyboard by directly typing into the cell
itself
7. S.NO A B C D
01 Value 1 Value 2 Added multiplied
02 10 20 30 200
8. A spreadsheet program is one of the main
components of an office productivity suit, which
usually also contains a word processor. a
presentation program, and a database
management system. Programs within a suite use
similar commands for similar functions.
Usually sharing data between the components is
easier than with a non-integrated collection of
functionally equivalent programs.
This was particularly an advantage at a time
when many personal computer systems used
text-mode displays and commands, instead of a
graphical user interface.
9. o Easier to edit or change data.
o Formulae for calculation to be done
automatically.
o There are built-in commands for calculating
averages, totals and so on.
o Different types of Charts can easily be
created.
o It can be use to create documents just like
a word processor.
o It may have a database management facility
to search data quickly.
10. The capabilities of spreadsheets are deskilling.
Workers no longer need to have specialist skills,
and must compete with cheaper unskilled labor.
Individual spreadsheets installed on each of the
PCs in an office also enable individuals to hoard
data and make their own forecasts without
cooperating with colleagues.
This phenomenon leads to duplication of both
data and effort throughout the organization. The
structure of the spreadsheet increases storage
requirements over the needs of raw data.
