Flow chart are used for logic representation. Flow chart is graphical/pictorial representation of programme logic. Three types of flow chart 1 sequential flow chart 2 conditional "          " 3 Iterative/loop "       " ➡ Flow chart are tools to express algorithm. ➡ being graphical in nature they are easier to understand. ➡ Algorithm can be reviewed and corrected easily. ➡ They provide effective algorithm for documentation.

Application software is written to solve a specific data processing task. There are two categories of applications software. 1 Pre written application software 2 User application software Example of applications software are word processing software,spreadsheet software,graphics software,entertainment software.        

                    DBMS stand for "data base management system"the word data base is made up of two word data and Base any row fact or figure is data.Ex- 14,John,4000,12th March 1999 etc... A data base is a collection of interrelated data.for example employee details of an organisation like employees name,employees number,salary,date of joining etc... can be called as data base. A data base management is software systems that allows access to data contained is a data base.objective of the database system is to provide a convenient and affective method of defining,storing and retrieving the information contained in the database.

A spreadsheet is simply a grid of boxes or cells set up in rows and columns.Every cell has a unique address corresponding to its row and column and first row is A1,cell in the third column and fourth.row is c4. Computer can find its way around the spreadsheet using those address and perform functions in the number you enter in those cells.

                A word processor is a software package which helps to enter and edit a document much faster than usual manual ways. A processing of acting on text like,cut,copy,paste,delete etc... are called word processing. Example of same word processor are word star,ms-word etc...some function that are possible using ms-word are given below. 1.Typing out the documents 2.Saving the document 3.Opening an existing document 4.Moving or copying paragraphs from one place in the document to another. 5.Finding the words and replacing them with another word. 6.Searching for spelling errors 7.Printing or sending the document via mail.

                            The software of the computer constitutes of rhe programmes and instructions to be executed.A programme is set of institutions that are arranged in a sequence that guides the computer to solve a problem.The process of riding a programme is called programming. A computer software can be broadly classified in to two categories. 1 System software/programme. 2 Application software/programme 1 system software/programme.  System programme are designed to make the computer easier to use.An example of systems software is operating system which consists of many other programmes for controlling input/output device,memory,processor etc...... 'C' language is broadly used to developed system software.systems software perform one or more of the following function. 1 support to develop application software. 2 support in executive of applications software. 3 monitor various hardware r...

                      Hardware is a physical component of a computer system.This is the actual machine that includes the mechanical,electrical and electronic components. Ex-keyboard,monitor,scanner,printer,hard disk. The hardware of a computer is divided into three major category. 1 CPU which contains arithmetic and logic unit for manipulating data. 2 A number of resister for strong data. 3 control circuit for fetching and executing instructions.
