2. DEFINATION A spreadsheet is a document that stores
data in a grid of horizontal rows and
vertical columns. Rows are typically
labeled using numbers (1, 2, 3, etc.),
while columns are labeled with letters (A, B, C, etc).
Individual row/column locations, such as C3 or B12,
are referred to as cells. Each cell can each store a unique instance of data.
By entering data into a spreadsheet, information can be stored in a more
structured way than using plain text The row/column structure also allows
the data to be analyzed using formulas and calculations.

3. COMMON FEATURES Custom functions Charts: line graphs, bar graphs,
Formulas
Custom functions
Charts: line graphs, bar graphs,
pie graphs,linestep graphs, scatter graphs
Cell formatting
Cell locking
Custom column groups
Cell merging (rows and columns)
Cell formats (Numbers, Strings, Currencies, Dates, Times)
Cut/Copy/Paste with single cells or ranges of cells
Custom names for columns and rows
Custom styles for columns, rows and column groups
Integration of images from the web
Operations like deleting and inserting columns/rows

4. ADVANTAGES & DISADVANTAGES
The facilities of spreadsheets make calculations
easier to understand by displaying stages of the
development of a sum, with the ability
to write notes explaining each line.
The grid encasing the cells in the spreadsheet
can either be visible or hidden in print outs, enabling
reports to be formatted from the display of the spreadsheet.
Templates containing the formulas for regularly used spreadsheets
increase productivity by removing the need for highly educated operators.
Spreadsheets can also interact with databases to populate reference fields,
automating almost the entire creation phase of the spreadsheet.
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.

5. EFFECTS ON EDUCATION Save time Organize displays of information
Spreadsheets save valuable time by allowing teachers and students to complete essential calculations quickly.Theysave time not only by making initial calculations faster and more accurate, but their automatic recalculation features also make it easy to update products such as grades and budgets. Entries also can be changed, added, or deleted easily, with formulas that automatically recalculate final grades.
Organize displays of information
Although spreadsheet programs are intended for numerical data, their capability to store information in columns makes them ideal tools for designing informational charts such as schedules and attendance lists that may contain few numbers and no calculations at all.
Support asking "what if" questions
Spreadsheets help people visualize the impact of changes in numbers. Since values are automatically recalculated when changes are made in a worksheet, a user can play with numbers and immediately see the result. This capability makes it feasible to pose "what if" questions and to answer them quickly and easily.
Increase motivation to work with mathematics
Many teachers feel that spreadsheets make working with numbers more fun. Students sometimes perceive mathematical concepts as dry and boring; spreadsheets can make these concepts so graphic that students express real delight with seeing how they work.
