IT APPLICATIONS CHAPTER 11 class XI (IP)

dear students
kindly learn these notes for IT Applications

IT APPLICATIONS

CHAPTER 11

LEARNING OBJECTIVES:

After studying this lesson the students will be able to:

Differentiate between front-end and back-end of an application.

Identify various components of the front-end of an application.

Design and develop simple IT applications.

List the impacts of ICT on society

IT- APPLICATIONS

1.e-Governance

e-Governance involves applications which are used by government agencies/organizations to provide better governance.

Benefits

To reach the citizens in an effective and transparent manner ICT enabled counters have

1. It helps the trainer to organize and manage his/her lesson plans

1. E-Learning is about giving freedom to people to learn whatever they want to learn and whenever they want to learn irrespective of age, caste, gender, economical background, or qualification of the learner

e-Learning websites and their salient features and societal impacts

1. w3schools.com ( Website Developers e-Learning site) –

At w3schools.com you will learn how to make a website. It offers free tutorials in all web development technologies

2. www.gcflearnfree.org -It is an educational part of the GCF mission

3. educationportal.mp.gov.in/public/multimedia.aspx - This government of Madhya

Pradesh portal provides multimedia tutorials on various topics of different subjects

like maths, science, social sciences etc.

4. ncert.nic.in/html/learning_basket.htm - This NCERT portal provides interactive

Social and Economic benefits of ICT:

•  Social networking sites help people remain in touch with their nears and dears

even when they are staying on opposite sides of the globe.

Social networking sites help like minded people come together and work for

processes and helps the government to keep check on defaulters.

Due to e-Banking and use of plastic money more money is put in circulation

leading to faster growth of GDP.

• e-Learning sites make quality study material available even to the students

staying at remote places.
