3. Scientific Application A large body of computer applications serve the scientist. Scientists use complex mathematical relationships and volumes of data, impossible to manage without the aid of computers Computers are used to perform scientific calculations, often to support military objectives Areas of study like DNA, nano – medicine and remedies of deadly diseases are completely dependent on use of the use of computers. Scientists use computers to simulate their projects. Computers are used to analyze the effect of flood, earthquake or fire on a particular building. Computers are also helpful in the study of oceans and space. They are used in development of new products and modification of existing products.

4. Word Processing Application Computers have replaced typewriters with word processing software. The term word processing covers a range of activities to write, edit and print documents. Word processing software provide a set of tools and commands for entering, editing and formatting text. Most common example of this software includes Microsoft Word. With computers we can have any number of prints of the same letter. The utilities like spelling and grammar check, find and replace a word are of great help in various word processing software.

5. Spread sheet A Spread sheet is a software tool for entering, calculating, manipulating and analyzing the sets of different data elements. A spread sheet contains worksheets having rows and columns. The intersection of a row and a column is called as a cell. Data is entered in the cells and each cell has a different name. Microsoft Excel is a common spreadsheet tool. A spreadsheet software offers a vast set of commands and tools to perform calculations on data as per the formulae written by users. Some of the most helpful features are automatic recalculation, cell formatting, sorting and filtering data etc. Spreadsheet software allow users to represent data in graphical manner. Spreadsheets are very popular in managing data of stores, schools, households, hospitals etc and their demand is increasing day by day.

6. E-Commerce E- Commerce is a new generation of commerce in which selling and purchasing is done through the internet and the payments are made online. With this you have no need to go to the showroom to purchase a particular product. Instead, you can just open the website of the manufacturer to see the details of the product and place the order online. Examples of such sites include ebay, myntra etc. By using e-commerce, user can save time to visit showroom and carry the goods to home. The user can effectively analyze the products and compare the features of the products provided on the website itself. With e-commerce, the business is not bound within the boundaries of states and country.

7. Business Businesses are the largest customers of the computer industry. Every type of business involves transactions with suppliers, employees and customers. People take orders through internet and make payments online. The computers are actively involved in such business. The computers with sophisticated softwares help business units from designing, advertising and selling products. Managers can effectively record, plan and present business information through computers. Computers help businessmen in creating budget plans, account management, inventory control etc.

8. Educational The field of education is touching new horizons with the help of computers. Computers are helpful to both the teacher and the students. There is no need of carrying huge books to have information from them as books are available in the form of CDs and students can read them on computers. Internet is an ocean of information and you can take any kind of information from it. Students are using computers for creating their projects and reports. With pictures and animations, the study of subject becomes very interactive and understandable, so students learn very effectively and quickly. Teachers can use multimedia aids of audio, video and animations to illustrate the complicated parts of lecture. Various interactive tutorial CDs are also available which are designed for self learning.

9. Industrial With adaption of computers in industry, the manufacturing cycle has become shorter and quick. Computer controlled machines work several times faster than conventional machines that produce products at a very slow speed. Modern car and other automobile plants use computer oriented assembly lines in which most of work is done by computer controlled machines to produce products at a very fast pace. This process is called computer aided manufacturing. Computers also help us to replicate the production of a particular part. The manufacturing industries also use computers for creating models of future products. These models are created with specialized software before creating the actual products. This technique is called as Computer Aided Design(CAD).

10. National Level Weather Forecating Computers are used for national and international level weather forecasting. Very powerful computers called Super Computers are generally used to control artificial satellites moving around the earth. These satellites constantly send information to the controlling computer, generally in the form of pictures, which are thousands in a second. Computer analyses the information coming from the satellite and predicts the change in weather i.e. temperature, pressure, humidity etc and warns about storms, heavy rains etc.

11. Planning With sophisticated computers and planning software, a businessman can create excellent plans to make the business a successful one. It involves study and analysis of very large volumes of present and past figures and calculation of the cost and time that will be required to complete the project. Before starting any project, planning is done to ensure that the project will be completed on time and with in budget. Many commercial computer applications are being used to create plans. These complex jobs are done with the help of computers, which calculate these figures without any errors and within a short span of time. These figures can be compared graphically and can be presented using presentation software.

12. Multilingual Application Computers are widely used in multilingual applications. These are the applications that support multiple languages e.g. hindi, english, french etc. A user can type in or just speak out the words in order to enter them into a computer. The spoken words are automatically converted from one language to other language by the software.
