Introduction
In science, network learning is more effective than any other learning process. Here a group of students work together in a structured way. A group of students discussing a lecture or students from different schools work together over the internet on a shared assignment. The students are individually accountable for their work and the work of the group as a whole is also assessed. In network learning co- operative groups work face to face & learn work as a team. The user is able to take the information to personalize and customize their learning experience. To meet their own personal needs. The learner is able to increase connections, interactions and sharing in networking which allows for effective learning. Networking learning provides social cohesion and better achievement among learners and develops deep emotions like respect and admiration for the expertise of others.
             Networking represents an innovative shift in the field of learning, providing, rapid access to specific knowledge and information. It offers online instructions that can be delivered anytime & anywhere through a wide range of networking situations such as web- based course ware, online discussion group, live virtual classes, video & audio streaming, web chat, online simulations and virtual monitoring.

Purpose of networking in personal growth

            Networking helps to learning and teaching of any kind. Any form of learning in which digital communication, electronic devices or the internet is used to support learning processes might be described as a form of learning.

·        It helps to develop expression power.
·        It helps to develop reasoning and thinking power.
·        It develops judgment and decision making ability.
·        To improving comprehension, speed & vocabulary.
·        To develop proper study habits.
·        To develop tolerance & ambiguity, risk taking capacity, scientific temper etc.
·        To build social relation among people who share interest, back grounds or real life connections. 

Purpose of networking in professional growth

               Companies must educate and train vendors, employees, partners and clients to stay competitive and a cost effective way. In profession, the networking programmers may require products and services supplied by a variety of vendors. The purposes are

·        To perform task analysis

To determine the task to identify the knowledge, skills and attitude required to complete task effectively.

·        To perform training needs analysis

Identify the target audience for the training

·        To reduce learning costs

As a small business owner, you know that online transactions cost a fraction as much those requiring paper or staff.

·        To motivate employees

It helps to an effective way to keep up with new technology, to generate new ideas 7 to keep your work force, fresh and inspired.

·        To expand the capabilities of the business
·        To track employee progress
·        To reduce time away from the job
·        To improve job performance
·        To support business objectives

Different types of networking
                             
Networking is a spatially diffuse structure with no rigidly defined boundaries, consisting of several autonomous nodes sharing common values or interests, linked together in inter dependant exchange relationships.  It is a supportive system of sharing or exchanging information and services among individuals, group or institutions having a common interest.

1.     Technical networking

In the case of technical networking various tools are used to exchange information. They are,
a) BSCW (Basic support for collaborative work): This is a tool designed in Germany. It is free to use for educational purposes. It enables and support for working in groups. Resources can be uploaded to work with them.
b) Synexgia: It is further developed version of BSCW. It offers logged, closed chat options & tools for visual communication. This is a combination of a synchronous map tool &an asynchronous BSCL (basic support for co-operative learning) tool.
C) FLE-3: FLE-3 environment was developed on pedagogical theory including computer supported collaborative learning. It has really good interactive communication tools.
d) Think.com: This is an oracle tool but free for any registered school worldwide. In addition to those tools, social network like twitter, blogs, linked in, face book are also used for exchanging information.
2.     Institutional networking
               In institutional networking, the information is exchanged between various institutions are possible. This helps in the development of these institutions. Some social networks such as English Baby are explicitly education focused and couple instructional peer environment.

3.      Personal networking
                       In personal networking two or more persons can exchange information among them. It helps to exchange variety of information between the people.

E-twinning
                       E-twinning is an example for personal networking. Here the resource persons share their practice and resources which leads to the development of the institution. The knowledge acquired by different individuals becomes an asset to group work. Indeed some European countries have already perceived this and have integrated into the national strategic plans.
Conclusion
                       Networking is an important one to learn science in learning process. It helps to increase the interest in students .It also helps to increase connections, sharing information in between students. Networking learning provides social cohesion and better achievement among learners and creates deep emotions in between learners. Networking also helps in different free id such as professional and technical field.

THINGS TO DO

12 THINGS YUO CAN DO ON  CLIMATE  CHANGE


Efficient lighting


Replace incandescent bulbs with compact fluorescents (CFLs). These use four times less energy and they last eight times longer. So you not only cut your electricity bills dramatically, you also save a lot of money on buying bulbs.

Use energy efficient electric appliances

They use two to 10 times less electricity for the same functionality and are mostly higher quality products that last longer than the less efficient ones. In short, efficient appliances save you lots of energy and money. In India, appliances like refrigerators and ACs have efficiency rating labels ranging from 1 to 5 stars, the higher numbers being more efficient.

Use an energy efficient computer

Buy a laptop instead of a desktop. It consumes five times less electricity. If you buy a desktop, get an LCD screen. Enable the power management function on your computer, the screensaver does not save energy. Check if your computer supports the more advanced speed step power management. Switching off a computer extends its lifetime, contrary to some misconceptions. Minimize printing and print on both sides of the paper. Laser printers use more electricity than inkjet printers.

Drive less

Walk, bike, carpool or take public transport. You'll save 1.5 kg of carbon dioxide for every 5km you don't drive. Use cars that run on cleaner fuels such as CNG and LPG. Switch off your car if you want to stop for more than two minutes.

Check your tyres

Keeping your tyres inflated properly can improve the fuel efficiency of your car. Every litre of petrol saved keeps 2.5 kg of carbon dioxide out of the atmosphere. Using radial tyres will help you save three to seven percent of fuel.

Use water carefully

Don't waste water. Use a mug of water when brushing your teeth, shaving or washing your hands and face. Instead of a shower or tub bath, use a bucket. Try to harvest rainwater in your locality. It takes a lot of energy to heat water- use less hot water and use efficient heating appliances.

Say no to plastic

Take a cloth bag with you when shopping. Use recycled paper. Avoid products with a lot of packaging.

Move your air-conditioning thermostat up two degrees

You could save about 900kg of carbon dioxide a year with this simple adjustment. Set the thermostat of the room air conditioner at 25C to get the most comfort at the least cost.

Use renewable energy

Sunlight can be used in many different ways to save energy. Use a solar water heater instead of an electric geyser. A 100 litre solar water heater can save around 1500 units of electricity every year. For lighting, use batteries that can be charged with sunlight. A solar cooker cooks rice and vegetables without losing their essential nutrients. Just leave the solar cooker outside in the sun to cook your food. If you live in a village, you can use biogas from cow-dung to save energy.

Plant more trees

A single tree will absorb one tonne of carbon dioxide over its lifetime.

Turn off electronic devices

Simply turning off your television, stereo, computer, fans, lights when you are not using them will save thousands of kilograms of carbon dioxide emissions a year.

Reuse & recycle

Recycling and re-using products like paper and bottles will help protect the environment. Use recycled paper. Recycle your office and household waste.
