Like many other fields computers have found hundreds of applications in the agricultural arena as well. With the growing population and demands of the society these days the development of newer ways to cultivate and farm has become quite urgent. Not to mention that livestock farming and crop production is not the only concern these days for farmers, having the proper technology to foresee the environmental impact and the climate is also important. One such system has been developed known as the Geographic Information System that is like a blessing for the local farmer. It can be used to detect problems like weeds, insects, and drainage. Also, it has applications like providing information about nutrients, soil pH, slope conditions, soil conditions etc. In addition to that it is used to check with things like crop scouting, tractor guidance, soil sampling, field mapping and irrigation. All this combines to give better crop yield to the farmer and lesser losses.

Electronic devices use the electricity to run. Many devices are being invented day to day. The devices use the flow of electrons and work on their energy to work. They are built up using the combinations of various circuits and chips. Now days many fancy electronic gadgets are also being developed to lure the customers to buy them. The use of electronic devices can be seen everywhere. They have become the basic need in everyones life and hence the development is also in demand. There are many companies who are manufacturing the electronic gadgets and devices but they have to be selected depending on your need and budget.

Less costly devices are also available which would fit into your budget but would not give the quality and all the options as in the other ones. There are many electronic devices from which the most commonly used ones are the refrigerators, laptops, digital cameras, mixers, driers, etc. They can be found easily in any living and have become a basic need for a living. They provide extraordinary features which attracts people to use it. Before they were needed the electronic supply continuously but now they use the chargeable batteries which can be charged and used for some time. It has allowed some of the electronic devices to be carried anywhere and can be used anytime. The development of the electronic devices have a long history which shows its long and steady development from very large to compact devices. Also now the technology is developed which is affordable and can be used by everyone. The electronic devices are best used to spread knowledge to any corner of the world. They also help to show things in a beautiful and different manner. Now days the computers and projectors are used to teach the students in an attractive manner and help them to learn better.

The modern devices began developing with the use of the vacuum tubes. They were in the electronic market dominating it for about 50 years. They were replaced due to their drawbacks. They were very large and produced huge amount of heat which was not desirable. They were not the amplifiers when they were developed but them they were able to amplify the signals. The next invention was the transistor which was invented in the year 1947 and replaced the vacuum tubes completely. The vacuum tubes needed a filament to get heated and generate electrons but the transistors did not need them. After the transistors, came the silicon integrated chips which combined more than one transistor on single silicon chip. But today the technology has been developed which has combined up to millions of transistors on a single chip. This has given rise to the technologies like the micro computers which make use of the microprocessors. The transistors are decreasing in size with every new invention. The microprocessor chip was invented in the 1968 but was first introduced by the Intel Corporation in 1971. It was the idea of a Japanese company which made on the basis of a calculators design. The invention was not given the acceptance for few years but was later accepted and is now being used in each and every new invention. The science and technology have also shown its new and interesting inventions in the electronic devices. The electronic devices have now reached new heights. The digital cameras, palmtops, i-pads, etc are developing increasingly and are highly in demand in the market. Their demand is making the researches to find something new in the electronics department. Also the field of electronics is also developing very well.
