hi

Hi all , How do you do And this blog about the ELECTRONICS THEORY And  ELECTRONICS

Importance of Electronics




Importance of Electronics

          Electronics dominate the world today and many of the people in it. Within the past twenty years or so, so many improvements and advancements in technology have created a world which relies on electronic services and communication. Now-a-days, it is not uncommon to own numerous electronics for one reason or another. All of them have a purpose and many of them seem quite necessary in day to day lives of people.
        One of the most popular and most important electronic today is the cell phone. It seems like everyone has a cell phone; even young children are becoming owners of their very own cell phones! Cell phones are an extremely popular form of communication and are relied upon by families, businesses, friends, and pretty much anyone who needs to talk on the phone.
          Although the aforementioned electronics are probably the two most important and growing electronics out there, there are numerous others which people turn to and rely on daily. Don’t forget about the television which is standard in homes across America and many other countries across the globe. The television and all the electronics you can hook up to the television such as video games, DVD players, blu ray, and more, are extremely popular forms of entertainment and are relied upon by most American families. Just like all other electronics, the television is continually being improved upon and advanced, and televisions are becoming more and more expensive with these improvements.

          Most of the machines in the industries are made to work with the help of computers, because computers can help them to work faster and also help them to make outputs of best quality and more quantity. In earlier days workers in the factories need to keep on monitoring the work and parameters to get the quality products from the machines. But most of the parameters required for making the best quality of the products will be measured by the computer and accordingly it will make the machine to work and make 100% quality materials.

Early electronic components

                         Vacuum tubes were one of the earliest electronic components. They dominated electronics until the 1950s. Since that time, solid state devices have all but completely taken over. Vacuum tubes are still used in some specialist applications such as high power RF amplifiers, cathode ray tubes, and some microwave devices.

Electronics


                     Electronics is the branch of physics, engineering and technology dealing with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies. The nonlinear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible and is usually applied to information and signal processing. Similarly, the ability of electronic devices to act as switches makes digital information processing possible. Interconnection technologies such as circuit boards, electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed components into a working system.
                 Electronics is distinct from electrical and electro-mechanical science and technology, which deals with the generation, distribution, switching, storage and conversion of electrical energy to and from other energy forms using wires, motors, generators, batteries, switches, relays, transformers, resistors and other passive components. This distinction started around 1906 with the invention by Lee De Forest of the triode, which made electrical amplification of weak radio signals and audio signals possible with a non-mechanical device. Until 1950 this field was called "radio technology" because its principal application was the design and theory of radio transmitters, receivers and vacuum tubes.
Today, most electronic devices use semiconductor components to perform electron control. The study of semiconductor devices and related technology is considered a branch of solid state physics, whereas the design and construction of electronic circuits to solve practical problems come under electronics engineering. This article focuses on engineering aspects of electronics.
