What is absolute cell addressing?

In spreadsheet applications, a reference to a particular cell or group of cells that does not change, even if you change the shape or size of the spreadsheet, or copy the reference to another cell

A formula or function is copied or moved to another location, any cell references in the formula or function get adjusted as well. However, there are some situations where a cell reference inside a formula must ALWAYS refer to the same spot.

An absolute cell address consists of the column letter and row number surrounded by dollar signs ($).

An example of an absolute cell address would be $C$4, $G$15, or $A$345.

Note: An easy way to add the dollar signs to a cell address is to click on a cell address and then press the F4 key on the keyboard.

An absolute cell address is used when you want a cell address to stay fixed on a specific cell.

This means that as a formula or function is copied and pasted to other cells, the cell addresses in the formula or function do not change.

Explain the features of MS-Excel MS Excel can be customized in a way that suits a user to achieve his goal. It is extensively used in financial organizations. The features of MS Excel are as followsWorkbooks: A document in MS Excel is called a workbook. Each workbook contains sixteen worksheets by default. A user can change this number by resetting the default options. Worksheets within workbooks make it easy to bind files of related information. When a user opens a workbook, he can use all the worksheets to perform a task.

Using keyboard: The following table provides different keyboard shortcuts for selecting a row, column, current cell, worksheet, etc.Entering Data in Series: A user can fill a range of cells either with the same value or with the series of values. This can be done using the Autofill handle (small square on the bottom-right corner of the active cell).



Cell References: MS Excel provides three types of cell references: relative, absolute, and mixed. Relative references refer to the cell relative to the given position. Absolute references refer to the specific cell irrespective of the position of the formula. The '$' sign is used to denote an absolute reference. Mixed references are a combination of both relative and absolute references. It has one absolute co-ordinate and one relative co-ordinate. $CI and C$1 are both examples of mixed references.

MS Excel allows fast searching and instant replacing of data. To search or replace the data entered by a user, he can use the Find or Replace command from the Edit menu.MS Excel provides the auto fit selection that adjusts the width of the column according to the widest entry in that column. A user can hide or unhide certain rows or columns. He can also provide the default column standard width.

MS Excel allows a user to align the characters in different ways by using the Alignment tab page of the Format Cells dialog box. The dialog box provides a number of alignment options.Auto-calculation: MS Excel spreadsheet allows a user to automatically recalculate the whole worksheet every time a change is made in a single cell. There are basically two kinds of recalculations.Charts: One of the most important features of MS Excel is a chart. MS Excel allows users to view data entered as tables in a graphical form as charts, which helps a user to easily understand, analyze, and compare data. Excel allows its users to create either two-dimensional charts or three-dimensional charts. A user can enhance the chart by adding chart items, such as data labels, a legend, titles, text, and gridlines. He can also do formatting on these items by using colors, alignment, fonts, and other formatting attributes. MS Excel also allows users to view charts along with the data by using embedded charts. These charts are included in the worksheet and can be copied, moved, and resized in the same way as can be done with any other graphical object.

Database: Data are raw facts, information is processed data, and a database is an organized collection of information. Every organization heavily depends upon databases to store, retrieve, and maintain



different kinds of data. MS Excel provides all this in the form of its database feature. In MS Excel, database can be created in two ways: Enter the data in the form of table in the worksheet.

What is a Database?

Database is a collection of data arranged in column and rows.Each row is called records and column field.This database can be quickly retivied or sorted depending on certain criteria .we can add a new field,add a column to the databaseThe definition of a database is a structured collection of records or data that is stored in a computer system. In order for a database to be truly functional, it must not only store large amounts of records well, but be accessed easily. In addition, new information and changes should also be fairly easy to input. In order to have a highly efficient database system, you need to incorporate a program that manages the queries and information stored on the system. This is usually referred to as DBMS or a Database Management System. Besides these features, all databases that are created should be built with high data integrity and the ability to recover data if hardware fails.

While storing data is a great feature of databases, for many database users the most important feature is quick and simple retrieval of information. In a relational database, it is extremely easy to pull up information regarding an employee, but relational databases also add the power of running queries. Queries are requests to pull specific types of information and either show them in their natural state or create a report using the data. For instance, if you had a database of employees and it included tables such as salary and job description, you can easily run a query of which jobs pay over a certain amount. No matter what kind of information you store on your database, queries can be created using SQL to help answer important questions.Obviously, many databases store confidential and important information that should not be easily accessed by just anyone. Many databases require passwords and other security features in order to access the information. While some databases can be accessed via the internet through a network, other databases are closed systems and can only be accessed on site.
