Application software- word-processing, spreadsheet, presentation Graphics, Data Base Management Software, Number System, Number System of computers- Binary. Octal, Hexadecimal, their conversion. Coding System- ASCII, EBCDIC. 

Application Software Applications are the software that a user uses to perform their daily routine. Such as writing letters, preparing databases, listening to songs, watching movies, etc. System software cannot be run without application software. Nowadays most of the software in the market is application software. Which are used in PC. The application software can be built according to its function.

Word - processing: - word processing refers to the word process, which means arranging the disorganized words and presenting them correctly. Under this, the setting of lines, paragraphs, pages etc. are done by decorating the words, this is completely opposite to typewriter. In which the word that is typed by the keyboard with the help of the word processor software can be seen on the monitor screen. If there is an error. So you can improve it. Apart from this, there are many options related to word processing, with the help of which documents can be prepared easily in a short time. Some important tools in this are - Find, Replace, go to, Auto text, Spelling Check, Table, Paragraph, Border style etc.

There are many toolbars to work in it, which we can do our word processing easily. Tool - is displayed as an icon in the toolbar, so that even a person with less knowledge can do word processing in it. Nowadays many advanced word processing software is available in the market. Different word processing software works in different operating systems like MS Word, Word Star, Word Perfect etc.

Spreadsheet: - Spread sheet is often used to display numbers tables and data in the form of graph chart etc. It is a table in which we store data in table format. In the database. There are many tools to process. Apart from this, there are different types of functions for different types of data. By which we can do our work easily. It has a total of 16384 columns and 10, 48, 576 rows. Cells consist of rows and columns. In which data is stored. Each cell has a cell address. . Which has an identity. The cell consists of the Address Row and the column.

In this, we can easily do different types of calculations. In this, we can also make a formula according to our calculations. It contains 255 work seats in a workbook.

Examples: - MS Excel, Lotus etc.

Presentation Graphics: - Through Presentation Software the user can present his talk on a big screen or on a computer screen through a projector and can present to a large number of audience. Through this, he can add pictures, graphs and tables etc. to his presentation. In addition, animation can add sound to it. With which he can make his presentation simple and easy to understand. With this, he can present his presentation lively. Use it to demonstrate business planning, education and strategy. can be done . The use of MS power point is best suited for this task. Nowadays, it is being used to present your ideas in every college, seminar, business promotion, politics, office meeting etc. With this help, we can present our ideas easily.

                  Data Base Management Software:

Through Data base Management Software we can collect and organize data. It is used in the work of data management from the Chatra level to the larger level. It is one of the major parts of computer technology. is . It can store business, government and all types of databases and perform various operations on it. like . Filtering data, adding new data, deleting data, etc. Through this we do our business and others. Can easily handle data of institutions. In today's era, electronic database in database software. Is stored. Apart from this, store data can be shared in it. Through this, we can manage the database easily. The following software is for this. Such as MS Axus, Fox Pro, SQL Server etc. 

In all database software, data is stored in table format. We can easily connect this database to various software. In these, we can easily generate reports etc.

Number System: - With the development of mathematics, many number systems have come into practice. The number of digits used in each number system is different, so that their bases are also varied. The number system name is also based on the number of digits used in it. In some popular numbering systems, decimal numbers binary, decimal, octal, hexa decimal are used. Thus the value of each in a number depends on the following.


  • Points
  • Number digit position
  • Number System Base


Decimal Number system: - The basis of this number system is ten, as it has a total of ten digits (0 to 9). The value of any number written in this number system has the following two properties. The first sign values ​​are digits from 0 to 9. The second local value is an increase in the order of the power of base ten in the right-to-left direction of the number. Like thousand -> hundreds -> tens -> units

Coding System: - Each key pressed by the computer keyboard has a signal input. Numbers ranging from 0 to 9 and alphabet or special symbols from A to Z etc. are a total of 256 letters. Each letter has a fixed binary number. Binary numbers have different signs to express letters in the computer. . Such as ASCII, EBCDIC, BCD etc. Each code assigns a certain number and arrangement to the binary key to express a letter.

ASCII CODE: - Its full name is American Standard Code for Information Interchange. 128 in it. There are seven binary digit codes for letters. This code consists of two parts. There is a four bit numeric part on the right side and 3 bit zone on the left side. Most micro processors and IBM PCs use this ASCII CODE. For example the value of A is 65. Its binary code is (1000001)2, as follows.


EBCDIC.  - Its full name is Extended Binary Coded Decimal Interchange Code. It is one letter to eight. Binary expresses with digits. It has a total of 256 different signs for all 256 characters. In an EBCDIC signal. There are two parts. The first numeric part expresses four bits from the right side. The second zone part that is four bits to the left. Expresses. This signaling system is used in IBM's mainframes and other large computers.  BCD - Its full name is Binary Coded Dacimal. Each of its digits is expressed by four binary digits. The following is a BCD code from 0 to 9.


EBCDIC. : - Its full name is Extended Binary Coded Decimal Interchange Code. It is one letter to eight. Binary expresses with digits. It has a total of 256 different signs for all 256 characters. In an EBCDIC signal. There are two parts. The first numeric part expresses four bits from the right side. The second zone part that is four bits to the left. Expresses. This signaling system is used in IBM's mainframes and other large computers.
