Electronic Commerce
Posted by admin in electronic tool on 11 17th, 2009Internet has provided innumerable benefits with not only making the world a smaller place, in terms of communication ease but has also revolutionized the concept of carrying on business not only in the local markets but in the global market scenario. Electronic commerce or simply e-commerce is the order of the day. It can be defined as the carrying of the business activities over electronic means and systems such as the computer networks and internet. Ecommerce first came into existence in the 1970 when electronic fund transfer and electronic data interchange were introduced. Since then ecommerce has made its way into all forms of business activities like buying and selling, marketing, inventory management and transaction processing. Electronic commerce thus has its importance in the business world. But just like any other form of business, electronic commerce also has certain advantages and disadvantages. These are discussed below:
Advantages of e-commerce
1. The most important advantage of electronic commerce is that it has enabled individuals and business establishments to reach customers globally. The geographical boundaries have been diminished as business has now reached far flung areas and even small to medium business enterprises are promoting their products and services.
2. Sales and profits have increased as business can now be conducted round the clock with transactions being carried over despite holidays.
3. Customers have also been beneficial with the introduction of electronic commerce, as now they have access to the world market and they can compare prices and buy good quality products at cheaper rates. Middlemen profit can now be overcome by reaching the original manufacturers directly over the internet.
4. Online shopping has proved a boon for those that had been restricted due to time constraints or other factors. Not only does online shopping saves time, it also saves money. With comparison shopping customers can now avail the same goods at reasonable prices.
5. Business concerns are benefited by electronic commerce in the sense that they save on huge advertising and marketing costs, upkeep of employees and middlemen profits. On the other hand they can increase the customer base by using the investment saved by providing quality customer care services.
Disadvantages of e-commerce
1. The biggest disadvantage of e-commerce is that there are still some reservations regarding the security of financial transactions being carried over the internet. People vary of divulging their personal information. The authenticity and legitimacy of all the e commerce sites cannot be gauged.
2. Electronic commerce offers no business for perishable items. This is because people still like to buy these items by the conventional way. The time taken for delivery is what could make the difference. Even returning or exchanging products purchased electronically pose some problems.
However after reviewing both the advantages and disadvantages of electronic commerce, one can surely say that the advantages far outweigh the disadvantages. What is truly needed to expand businesses to a greater number of people is to build trust and overcome technical problems. This would surely change the present scenario and help in making electronic commerce adjust to the requirements of the people.

Posted by admin in electronic tool on 10 18th, 2009Few things are more exciting and rewarding than building something that really works. Most kids love the challenge of building their own electronic devices, whether it’s a simple robot or a bedroom alarm to keep out little siblings.
Various electronic kits are available, and the potential benefits go beyond the finished product. For a start, it’s a hands-on opportunity to become familiar with some terminology. By high school, science classes often include an introduction to electronics concepts, including circuit diagrams, resistors, and diodes. Kids who build electronics learn about basic physics, electricity, and how electronic devices work.
These are pretty challenging abstract concepts, which can be brought to life by using electronic kits to connect the right parts. For instance, rather than looking at a computer and seeing only a box with a screen, electronics enthusiasts can get their hands on real parts to help them see and better understand the inner workings and infinite expansion possibilities.
Electronic kits contain multiple parts, diagrams, and instructions. To be successful and create a working device, kids need to follow instructions systematically. Starting with electronic kits for beginners, there are multiple levels of difficulty to explore. Kids learn how to read instructions carefully and how to interpret schematic diagrams, developing both spatial and logical skills.
Building electronics requires persistence and patience. Starting with simpler kits allows these skills to be learned gradually. Snap-together versions are more gratifying for beginners, who are getting accustomed to the parts and language. Later, more difficult assemblies become interesting.
Electronics does not have to be a solitary pursuit. Some children’s kits, such as the Elenco Snap Circuits Jr 100, include interactive games to be played with friends. While most beginners start with electronic kits, there are endless possibilities for more advanced enthusiasts. In fact, there are clubs and online hobby groups. As projects get more complicated, kids can move on to more advanced electronic kits. Elenco Snap Circuits Jr 100 is a great place for beginners, but after mastering it, kids can advance to Elenco Snap Circuits 300 and Elenco Snap Circuits 500. There are also other brands available, such as Thames and Kosmos.
Have a science fair coming up? Electronic projects are an interesting way to explore physical concepts. Not only can a budding scientist build his or her own electronic device, but then there are many possible experiments that can be done with instruments like photo-electric cells, electromagnets, and generators.
Even beginners can make a wide variety of devices using Elenco Snap Circuits Jr 100, from radios and doorbells to a flying saucer. With so many options and parts, kids can experiment to build their own creations. Then there are electronic kits available that are specifically designed with one purpose in mind, such as making robotic vehicles, hydroponic gardens, race cars, weather observation centers, motorized dinosaurs, and digital recording instruments.
Most beginner electronic kits are solder-free, so they are straightforward and accessible for children. With practice and advancing skills, older kids can learn how to solder. Once this is mastered, there are many intriguing projects to make. Light dimmer switches, LED displays, combination code locks, and digital clocks make nice additions to any room. So next time you’re looking for an interesting and educational activity, think about an electronic kit.
