MS-EXCEL is a component of the Microsoft Office software suite. It is a multi-row and multi-column electronic spreadsheet used to organise data, graphically represent data(s), and perform various calculations. It is made up of 1048576 rows and 16384 columns, with each row and column forming a cell. Each cell has an address determined by the column name and row number, such as A1, D2, and so on. This is also known as a cell reference.

​

Cell references: A cell reference is the address or name of a cell or a range of cells. It aids the software in determining which cell contains the data/value to be used in the formula. We can refer to cells in other worksheets and programmes.
